Titanium screws have the highest price among screws of many materials. Why are titanium screws so expensive? Let's take a look at what kind of metal is titanium screw. In addition to its application in the screw industry, which industries are also used? Titanium screws have the characteristics of low density, high specific strength, good corrosion resistance, low thermal conductivity, non-toxic, non-magnetic, weldable, good biocompatibility, and strong surface decoration. It is a lightweight, high-strength, corrosion-resistant Structural materials are widely used in high-precision fields such as aerospace, medical equipment, sporting goods, and precision products.
1. Medical treatment: Titanium metal material is widely used in the manufacture of medical equipment, artificial hip joints, knee joints, shoulder joints, hypochondriac joints, cranium, active heart valves, and bone fixation clips. Before the use of titanium, medical orthopedics usually used stainless steel as a bone material. However, the use of stainless steel has a disadvantage, that is, it will rust. This has to be taken out after the bone is healed. However, this is for patients, It is a very painful thing.
After the use of titanium "artificial bones", the orthopedics technology is completely changed, and the stainless steel sheet is abandoned. You only need to use titanium plates and titanium screws on the damaged areas of the bones. After a few months, the bones will re-grow in the holes and screws of the titanium plates. The new muscle fibers are wrapped in the titanium plates, and the titanium bones It is connected to flesh and blood just like real bones, and plays a role of support and reinforcement.
Second, the field of sporting goods: the advantages of high strength and low density also make titanium widely used in the field of sporting goods. For example, high-quality bicycle frames and golf clubs are usually made of titanium, which is not only strong and durable, but also light in weight.
3. Application of titanium screws in aerospace and military fields. Titanium has very good durability, so in aircraft engines, bulletproof parts, strengthening parts, reinforcement parts, combustion chambers, turbine shafts, turbine disks, nozzles, etc., most of them are made of titanium alloy materials. It can be seen that titanium is a metal element. The best material for aircraft production.
