How Titanium Helps Lives
Titanium is a highly desirable metal that works great for a variety of functions and in many different industries. As it is a metal, one would likely think titanium is best used in manufacturing, aerospace, automobile, marine, firearms, military and building. You would be right to associate titanium with these industries.The biggest reason titanium is so popular is its unique, favorable characteristics. Titanium behaves differently from other metals and has properties that make it do things other metals simply can’t.Among the highest regarded, favorable properties of titanium include its durability and strength, light weight, flexibility, corrosion resistance and biocompatibility.The latter characteristic of titanium is what makes it popular to use in the medical and dental industry. Titanium’s biocompatibility property is what makes it a life-saver.How is titanium used in the medical and dental industries?In the field of medicine, you’ll find titanium used in:Joint ReplacementsTitanium’s biocompatibility means that it can be fused to bone without the risk of severe side effects, reactions or infection. The composition of the titanium is readily accepted by a patient’s body. Whenever any type of invasive surgery to have joints inserted needs undertaking, chances are, the surgeons will use titanium for the necessary replacements.Dental ImplantsMuch like bone and joint replacement procedures, titanium is also heavily used in dentistry for dental implants. The part of the implant that goes into the jawbone is titanium. Titanium’s biocompatibility makes the implant accepted by the body and encourages bone growth. As a result, a patient’s gums are strengthened, the implant is sturdy and at a low risk of infection, complications, and discomfort.SunscreenTitanium doesn’t come in just a solid state, but it can also come in the form of powder. Besides titanium rods being placed inside the body, titanium powder can be applied to the skin for an effective sunscreen. The titanium oxide (titanium powder) prevents the sun’s harmful UV light from penetrating the skin.3D Printing With TitaniumChances are, you’ve heard of 3D printing, which has yielded amazing results and possibilities. 3D printing has many advantages over traditional manufacturing including a faster turnaround time, greater accuracy and the ability to produce customized, highly detailed parts.The success of 3D printing has made it a good fit for the medical and dental industries in producing implants, crowns, artificial joints, screws, plates, and prosthesis.It was inevitable that the success and technology of 3D printing would be combined with the durability, lightness, and corrosive-resistance of titanium.Titanium 3D printing has yielded even more advantages over traditional 3D printing including:1. Greater Design Complexity: The use of titanium powder creates a minimum thickness of .3-.4 millimeters which allow for more detailed and complex designs than what can be accomplished in traditional 3D printing.2. Excellent Strength and Durability Properties: The strength and durability of titanium aren’t lost during the melting process of 3D printing, meaning the resulting product is durable and strong. In fact, larger products can be produced with titanium 3D printing instead of piecing together smaller portions.3. Quicker Turnaround Time: Products manufactured using titanium 3D printing typically take from a few hours to a few days to complete.In titanium 3D printing, fine powder of titanium 6Al-4V is used. This specific grade of titanium is non-toxic, biocompatible, has a high melting point (3200 degrees F), is strong and durable, is lightweight and corrosion resistant.The unique properties of titanium have made it ideal to use in a variety of industries, including medicine and dentistry. The dental implants, joint replacements, sunscreen, screws and plates made of titanium have not only improved the quality of life for patients, but in some cases, they have saved lives.Xinnuo Titanium is a with a leading titanium supplier large inventory of titanium sheet, plate, bar and more available in the grade you need.

Preparation methods of 3D printing raw material
\'Additive manufacturing\', also known as \'3D printing\', has become one of the most advanced manufacturing technologies with nearly 30 years of rapid development.\'Additive manufacturing\' has been widely used in aerospace, automotive, medical and other industries.Refer to the definition given by ASTM:\'Additive manufacturing\' is the process of connecting materials into objects based on a 3D data model. Compared with the traditional way, \'Additive manufacturing\' technology does not require molds, the cycle from design to finished product is shorter, and is not limited by structure and materials.Due to the above advantages, the \'Additive manufacturing\' technology has been praised by some European and American experts as the disruptive technology of the‘ third industrial revolution. Spherical metal powder material is the raw material and consumable of metal additive manufacturing (3D printing) process. Due to the different applications and manufacturing processes requirements, its preparation methods are also different. According to the preparation process, manufacturing methods mainly includes physical and chemical methods and mechanical methods. Current metal powders for additive manufacturing are mainly concentrated in materials such as titanium alloys, high-temperature alloys, cobalt-chromium alloys, high-strength steels, and mold steels.Plasma Rotating Electrode-comminuting Process (PREP), Plasma atomization PA (Plasma Atomization) andInduction-melting Gas Atomization (GA) are the current main preparation methods for metal powders for additive manufacturing. All these can produce spherical or near-spherical metal powders. Plasma Rotating Electrode-comminuting Process (PREP) is a spherical powder preparation process developed in Russia. The principle is shown in Figure 1. The metal or alloy is processed into a bar material ,then heated the bar by plasma. At the same time, the bar material rotates at a high speed, and the melted droplets are refined by centrifugal force, then which will solidify and spheroidization transform to powder by the surface tension in an inert gas environment. Plasma atomization PA (Plasma Atomization) is Canada AP & C\'s unique metal powder preparation technology. The plasma torch installed symmetrically on the top of the melting chamber forms a high-temperature plasma focus, the temperature can even be as high as 10000K, the special feeding device sends the metal wire into the plasma focus, the raw material is quickly melted or vaporized, and the plasma is impacted at high speed Dispersed and atomized into ultra-fine droplets or aerosols, in the process of flying deposition in the atomizing tower, heat exchange cooling and solidification into ultra-fine powder with cooling argon gas passing into the atomizing tower, the schematic diagram of PA equipment is shown in Figure 2. The metal powder prepared by PA method is nearly regular spherica, the overall particle size of the powder is fine. At present, the common techniques for gas atomization preparation of metal powder materials for additive manufacturing include Vacuum Induction-melting Gas Atomization (VIGA) and Electrode Induction-melting inert Gas Atomization (EIGA), the principles of the two methods are shown in Figure 3 and Figure 4. Among them, the VIGA method is mainly suitable for the production of iron-based alloys, nickel-based alloys, cobalt-based alloys, aluminum-based alloys, copper-based alloys and other powders, while the EIGA method is mainly applied to active metals and their alloys, intermetallic compounds, refractory metals Preparation of powder materials such as titanium and titanium alloys, titanium aluminum intermetallic compounds. Now our company will build a production line product the metal powder is used for 3D printing in the method of EIGA. Compared with other methods, EIGA method has the advantages of material saving, flexible production and more fine powder output in preparing active metal powder, so it is suitable for the production and preparation of titanium alloy powder for SLM process.Our company is willing and have ability to provide all kinds of high quality metal powder used for 3D printing for you.

SUT-DK-TB ultrasonic automatic flaw detector is being tested
Ultrasonic testing, abbreviated as UT, also known as ultrasonic testing, is the use of ultrasonic technology for testing, is one of the five conventional nondestructive testing methods. Characteristics of ultrasonic wave1. Ultrasonic beam can concentrate on a specific direction and propagate along a straight line in the medium, showing good directivity.2. Attenuation and scattering will occur during ultrasonic wave propagation in the medium.3. Ultrasonic wave will produce reflection, refraction and wave pattern conversion at the interface of heterogeneous media.By using these characteristics, the reflected waves from the interface of defects can be obtained, so as to achieve the purpose of detecting defects.4. Ultrasonic waves have much more energy than sound waves.5, ultrasonic transmission loss in the solid is small, detection depth is large, because the ultrasonic in the heterogeneous interface will occur reflection, refraction and other phenomena, especially can not pass through the gas-solid interface.If there are defects in the metal such as pores, cracks, delamination (gas in the defect) or inclusions, all or part of the reflection will occur when the ultrasonic wave propagates to the interface between the metal and the defect.The reflected ultrasonic wave is received by the probe, and processed by the circuit inside the instrument, the waveform with different height and certain distance will be displayed on the fluorescent screen of the instrument.The depth, position and shape of the defect in the workpiece can be judged according to the changing characteristics of the waveform. Test specifications for Ф 6.0 to Ф 40 mm in diameter tube, rod, precision can reach the domestic leading level, the minimum detectable 0.3 mm flat bottom hole defect equivalent size, tube, rod surface precision can reach 0.8 * 0.8 * 3 mm), the highest detection rate can be up to 3 m/min, which can realize tube bar automatic high precision detection and greatly reduce the influence of human factors on the detection accuracy.

XINNUO Titanium bar for hip joint
Titanium material is the most corrosion resistant and biocompatible of all implant materials, because its low density, high mechanical strength, excellent corrosion resistance, and biocompatibility with bone. Pure titanium is used for hip cup shells. The high strength Ti-6AI-4V and Ti-6Al-7Nb alloy is mainly used for stems of femoral components with wear-resistant CoCrMo metal or Al2O3 ceramic ball heads. Baoji Xinnuo New Metal Materials Co., Ltd. can produce the Grade 3, Grade 5(Ti-6Al-4V), Ti-6Al-7NbTitanium bar for hip joint with Ø30, Ø40, Ø45, Ø50, Ø55, Ø65, Ø73mm. The bars’ are produced as per the standards ASTM F67, ISO 5832-2, ASTM F136, ISO 5832-3, ASTM F1295, ISO 5832-11. The bars are with good elasticity, high strength, good metallographic structure and good abrasion resistance.
Selection of acetabular prosthesis
The prosthesis is hemispherical in shape, and the biostationary acetabulum consists of a acetabular cup and a lining. The cement-stabilized acetabulum has no acetabular cup but a polyethylene lining.It is generally believed that the biofixation of acetabulum is better than cement fixation, so the combination of biofixation of acetabulum and cement fixation of femoral stalk appears, which is called hybrid fixation of total hip joint.However, the acetabulum should be fixed with bone cement if the patient is too old (over 70 years old) for osteoporosis and dysplasia of bone growth.It is technically required that the acetabulum be filed to the cancellous bone, fully rinsed, the bone bed drilled and pressurized to allow cement to penetrate into the cancellous bone and form a 2 ~ 3mm cement shell. The surface coating of the biofixation acetabular cup is critical for the long-term stability of the prosthesis, especially for the acetabular dysplasia (DDH). The contact area between the bone and the acetabular cup is small, and good bone penetration is more important.The surface treatment of prosthesis can be divided into four categories: surface macroporous, surface microporous, surface coating and double coating.The macroscopical interlocking prosthesis with the surface macropore, that is, the pearl surface treatment, has been basically eliminated, and the surface micropore and double coating have better effect, while the acetabular cup with the rough surface treatment has crossed effect.There are also some rotary acetabular cups that can achieve good initial stability in DDH treatment, but they are opposed by many scholars because once loose, more bone is lost. Because the elastic modulus of titanium alloy is closer to that of femur than that of cobalt-cr-mo alloy, the biological femoral stem prosthesis is generally made of titanium alloy.The surface treatment is the same as the acetabular cup.There are conical, rectangular, cylindrical, anatomic, combined and so on.Taper shank and anatomical shape fixed idea is maximum filling the marrow cavity, they recently adopted in more bone combined with good coating, such as surface pores or double coating, midway through the rough surface, far end is smooth, the purpose is to maximize the recent and bone combined to take more pressure, middle loose union, doesn\'t far end and bone union, only have the effect of maintaining prosthesis position, the sectional stress shelter effect of surface treatment is to avoid.
