In recent years, the application of titanium screws has become more and more extensive. Among screws of the same specification, the price of titanium screws has always been higher than that of other materials, but its performance and application range are irreplaceable with carbon steel screws and stainless steel screws. Advantage.
Titanium screw products have the following advantages:
1. Small density and high strength: The density of titanium metal is 4.51g/cm3, which is higher than aluminum and lower than steel, copper and nickel, but the specific strength is the highest among the above metal materials.
2. High corrosion resistance: Titanium is very stable in many media, such as titanium is the most corrosion-resistant in oxidizing, neutral and weakly reducing media.
3. Heat resistance and low temperature resistance: the new titanium alloy screws can be used for a long time at 600 ℃ or higher. Titanium alloys TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V) and Ti-2.5Zr-1.5Mo and other low-temperature titanium alloys, which maintain good ductility and low ductility at -196-253℃ Toughness, avoiding the cold brittleness of metal, is an ideal material for low temperature containers, storage tanks and other equipment. Most of the titanium screws produced by WorldCom are directly supplied to submarines, aviation power, high-end kitchen utensils, and unmanned vehicles, making them not only resistant to high temperatures, but also normally used at ultra-low temperatures.
4. Titanium is a non-magnetic metal, non-toxic, and will not be magnetized in a large magnetic field. With the enhancement of everyone’s health awareness, titanium screws are widely used in medical auxiliary treatment. Titanium screws have good compatibility with human tissues and blood even in the human body. At present, the main products of titanium are heart stents, intramedullary nails, dental implants, therapeutic equipment and some physical therapy equipment that are in contact with the human body. The fastener parts in these devices must also be titanium products.
