Metric Titanium Screws Performance

The advantages of metric titanium screws are ultra-light, corrosion-resistant, anti-oxidation, bio-compatible, low-temperature and high-temperature resistance, low modulus of elasticity, good gas absorption performance, etc., and these advantages mainly depend on some characteristics of titanium itself.

First, the density is small, the specific strength is high.

The metal titanium has a density of 4.51 g/cm 3 , which is higher than aluminum and lower than steel, copper and nickel, but the specific strength is at the top of the metal.

Second, corrosion resistance

Titanium is a very active metal with a low equilibrium potential and a high tendency to thermodynamically corrode in the medium.

Third, good heat resistance

The new titanium alloy can be used for a long time at 600 ° C or higher.

Fourth, good low temperature resistance

Low-temperature titanium alloys represented by titanium alloys such as TA7 (Ti-5Al-2.5Sn), TC4 (Ti-6Al-4V) and Ti-2.5Zr-1.5Mo, whose strength increases with decreasing temperature, but the plasticity changes are not Big. It maintains good ductility and toughness at low temperature of -196-253 °C, avoids cold and brittleness of metal, and is an ideal material for equipment such as cryogenic vessels and tanks.

Five, strong anti-damping performance

When metal titanium is subjected to mechanical vibration and electrical vibration, it has the longest vibration decay time compared with steel and copper metal.

Six, non-magnetic, non-toxic

Titanium is a non-magnetic metal that is not magnetized in a large magnetic field. It is non-toxic and has good compatibility with human tissues and blood, so it is used by the medical community.

Seven, tensile strength and its yield strength are close

This property of titanium indicates that its yield ratio (tensile strength/yield strength) is high, indicating that the metal titanium material has poor plastic deformation during forming.

Eight, good heat transfer performance

Although the thermal conductivity of titanium is lower than that of carbon steel and copper, the wall thickness can be greatly reduced due to the excellent corrosion resistance of titanium, and the heat exchange between the surface and the vapor is droplet condensation, which reduces the heat and titanium surface. Non-fouling also reduces thermal resistance, resulting in a significant increase in the heat transfer performance of titanium.

Nine, low modulus of elasticity

The modulus of elasticity of titanium is 106.4 GPa at room temperature, which is 57% of steel.

Ten, inhalation performance

Titanium is a very chemically active metal that reacts with many elements and compounds at elevated temperatures. Titanium inhalation mainly refers to the reaction with carbon, hydrogen, nitrogen and oxygen at high temperature.

Therefore, metric titanium screws can be used in transportation, aviation, chemical, marine, life, medical, energy, food and other fields.
