Advantages of titanium screws

       In recent years, the titanium screws have become familiar to more and more people, its application has been increasingly wide and deep. Comparing with the carbon steel and stainless steel screws, the performances and application’s range of the titanium screws have the irreplaceable advantages.

  1. Small density, high strength:

The density of titanium is 4.51g/cm3, higher than aluminum and lower than steel, copper, nickel, but the titanium has the highest specific strength among the above metal materials.

  1. High corrosion resistance:

The titanium is very stable in many media, for example, titanium is extremely corrosion resistant in oxidizing, neutral and weakly reducible media.

  1. Heat resistance and low temperature resistance:

The new titanium alloy screws can be used for a long time at temperatures of 600 °C or higher. The 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, ,they can maintain good ductility and toughness at the low tempretura such as -196-253℃ and avoid metal cold brittleness, so they are the ideal materials for low-temperature containers, storage boxes and other equipments.

  1. Non-magnetic and non-toxic

The titanium is a non-magnetic and non-toxic metal, in a large magnetic field will not be magnetized, with the enhancement of people’s health awareness, the titanium screws are widely used in medical auxiliary treatment, they also have good compatibility with human organs and blood even in the human body, and the main products of titanium at present are cardiac stents, intramedullary nails, implants, treatment instruments and some physiotherapy equipment that has more contact with the human body. The fastener components in these devices must also be titanium products.

      Because of the titanium screw’s characteristics, such as light weight, high strength, small density, rust-proof, corrosion-resistant, high temperature resistance, low temperature resistance, and other characteristics, it is mostly used in military, aviation, medical, chemical and other special environments.
