Titanium screws are so widely used, what are their advantages?

In recent years, the application of titanium screws has become more and more widespread. Among the screws of the same specifications, 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. Low density and high strength: The density of metal titanium is 4.51g/cm3, which is higher than aluminum but lower than steel, copper, and nickel, but its specific strength is the first among the above metal materials.

  2. High corrosion resistance: Titanium is stable in many media. For example, titanium is most resistant to corrosion in oxidizing, neutral and weak reducing media.

  3. Heat resistance and low temperature resistance: The new titanium alloy screw can be used for a long time at 600℃ or higher. Low temperature titanium alloys represented by titanium alloy TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V) and Ti-2.5Zr-1.5Mo, etc., maintain good ductility and low temperature at -196-253℃ Toughness, avoiding the cold brittleness of metals, is an ideal material for cryogenic containers, storage tanks and other equipment. Most of the titanium screws produced by WorldCom Metals are directly supplied to submarines, aviation power, high-end kitchen utensils, and unmanned vehicles, so that they can not only withstand high temperatures, but also can be used normally 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 increase of 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, treatment instruments and some physical therapy equipment that are in contact with the human body. The fastener components in these equipment must also be titanium products.
