Description:
Melting Point:3017 °C
Density: 16.65 g/cm3
Product range:Pure tantalum&Tantalum tungsten alloy
Tantalum is dark, dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity.
It has a melting point exceeded only by tungsten and rhenium.
As a high melting point metal, tantalum possesses a low vapour pressure and good electrical and thermal conductivity up to very high temperature.
The advantages of Ta are excellent corrosion resistance, high high-temperature strength, good machinability and good biocompatibility.
