What are the advantages and characteristics of titanium screws, which are widely used?
In recent years, the application of titanium screws has become increasingly widespread. Among screws of the same specification and model, the price of titanium screws has always been higher than other materials. However, its performance and application range have irreplaceable advantages over carbon steel screws and stainless steel screws.
Titanium screw products have the following advantages:
1. Low density, high strength: The density of titanium metal is 4.51g/cm3, higher than aluminum and lower than steel, copper, and nickel, but its specific strength ranks first among the above metal materials.
2. High corrosion resistance: Titanium is very stable in many media, such as oxidizing, neutral, and weakly reducing media, making it corrosion-resistant.
3. Heat resistance and low temperature resistance: The new titanium alloy screws can be used for a long time at temperatures of 600 ℃ or higher. Low temperature titanium alloys represented by titanium alloys TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V), and Ti-2.5Zr-1.5Mo maintain good ductility and toughness at low temperatures of -196-253 ℃, avoiding metal cold brittleness. They are ideal materials for low-temperature containers, storage tanks, and other equipment. The vast majority of titanium screws produced by Shishitong Metal are directly supplied to submarines, aviation power, high-end kitchenware, and autonomous vehicles, making them not only resistant to high temperatures but also able to function normally at ultra-low temperatures.
4. Titanium is a non-magnetic metal, non-toxic, and will not be magnetized in large magnetic fields. With the increasing awareness of health, titanium screws are widely used in medical adjuvant therapy. Titanium screws can have good compatibility with human tissues and blood even in the human body. Currently, titanium's main products are heart stents, intramedullary nails, dental implants, therapeutic devices, and some physical therapy equipment that come into contact with the human body. And the fasteners in these devices must also be titanium products.
