6 characteristics of titanium alloy

Titanium metal does not contain heavy metals and has good compatibility with human tissue and blood. It is often used as human implant parts and is widely used by the medical community. Non-magnetic, will not be magnetized in strong magnetic field,

Titanium's high tensile strength and yield strength mean that titanium materials are not easily deformed by pressure or tension after forming. Its hardness isHRC30-50, higher than steel. Due to the large ratio between the yield limit of titanium and the elastic model, titanium has a large resilience during molding.

New titanium alloys can be used for long periods at temperatures of 600°C or higher. It maintains good ductility and toughness at low temperatures of -196-253°C, avoiding the cold brittleness of metal. It is an ideal material for low-temperature containers, storage boxes and other equipment.

The density of titanium is 4.506-4.516 g/cubic centimeter (20°C), which is higher than aluminum and lower than iron, copper, and nickel. But the specific strength ranks first among metals.

Titanium has a great affinity with oxygen. In air or oxygen-containing media, a dense, highly adhesive, and inert oxide film is formed on the titanium surface, which protects the titanium matrix from corrosion. Even due to mechanical wear, it will quickly heal or regenerate itself, which shows that titanium is a metal with a strong tendency to passivate. The titanium oxide film always maintains this characteristic when the medium temperature is below 315°C.

Although the thermal conductivity of titanium metal is lower than that of carbon steel and copper, due to titanium's excellent corrosion resistance, the wall thickness can be greatly reduced, and the heat exchange method between the surface and steam is dropwise condensation, which reduces the heat group and the titanium surface No scaling can also reduce thermal resistance, significantly improving the heat transfer performance of titanium.
