Titanium screw with the traditional screw different : titanium screws and stainless steel, iron, copper screw is the same, just material is titanium, titanium materials are commonly gr2 pure titanium and titanium alloy gr5 material. Titanium screw raw material is more expensive, is also very beautiful, seems to arts and crafts, corrosion resistance. titanium and titanium screws comparely has a high price.
As a feedstock for the production of titanium screw element, titanium is a kind of highly reactive metal, compared with the traditional stainless steel, titanium screw has better flexibility and oxidation resistance.Wide range of applications in various industries. Ordinary stainless steel screws in a high-pressure environment compared with titanium screws, titanium screws compressive ability is stronger, so in the aerospace of metal, all choose titanium alloy screw, the titanium screws as one of the fastenings.
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.
