The performance and application range of titanium screws have irreplaceable advantages over carbon steel screws and stainless steel screws.
1.Small density and high strength: the density of titanium is 4.51g/cm3, higher than aluminum and lower than steel, copper and nickel, but the specific strength is the first among the above metal materials.
2.High corrosion resistance: titanium is very stable in many media, such as titanium in oxidation, neutral and weak reducibility and other media is corrosion resistance.
3.Heat resistance and low temperature resistance: the new titanium alloy screws can be used at 600℃ or higher temperature for a long time. Titanium alloy TA7 (Ti-5Al-2.5Sn), TC4(Ti-6Al-4V) and Ti-2.5Zr-1.5Mo as the representative of low temperature titanium alloy, at -196-253℃ low temperature maintain good ductility and toughness, avoid metal cold brittleness, is the ideal material for cryogenic vessels, storage tanks and other equipment.
4.Titanium is a non-magnetic metal, non-toxic, in a large magnetic field will not be magnetized, with the increase of health awareness, titanium screws are widely used in medical adjuvant treatment. Titanium screw is soluble in human tissues and blood even in human body. At present, the main products of titanium are heart stent, intramedullary nail, dental implant, therapeutic instrument and some physical therapy equipment that have more contact with human body. The fastener components in these devices must also be titanium products.
At present, the main stock of titanium screws:
