Performance and Annealing Process of TC4 Titanium Alloy Material

Medical titanium alloy medical instruments are the third generation surgical instruments after carbon steel and stainless steel. In order to improve the anti-rust performance of stainless steel appliances, surface treatments such as chrome plating and electropolishing are often required. But chromium is toxic, and the peeled off chromium layer will have a certain impact on the human body. The medical titanium rods produced by many medical titanium rod manufacturers are used in medical devices.

The benefits of medical titanium alloys as medical devices are:

1. The equipment is light and handy, which can reduce the damage to blood vessels, muscles and organs during the operation, and reduce the fatigue of the doctor. The medical titanium equipment is more suitable for fine microsurgery operations;

2. Good corrosion resistance and non-toxicity, the equipment does not rust, the wound is not easy to be infected, and the wound heals quickly;

3. The medical titanium alloy has moderate elasticity and is suitable for pliers, tweezers, micro scalpels and other instruments;

4. When operating under a shadowless lamp, the reflective performance of medical titanium is weaker, which is more suitable than stainless steel;

Medical titanium medical instruments mainly include scalpel, surgical forceps, surgical forceps, chest expander, suture needle, suture thread, etc. Medical titanium wire is used as a surgical suture. Compared with other materials (such as stainless steel wire), it has the advantages of small tissue response and good torsion resistance. After suturing, the surgical wound is not easy to be inflamed, and the bone suture site is not easy to shift. The suture thread generally uses medical titanium wire (TA1 or TA2 wire) with a diameter of 0.5 to 0.8 mm. In addition, the soft elasticity produced by the titanium-nickel alloy wire can promote the rapid healing of the wound.

In addition, medical titanium alloy is also an important material for auxiliary rehabilitation equipment, such as wheelchairs, crutches, splints, and medical equipment.
