Which should you choose, pure tungsten or alloy?
Tungsten and its alloy has perfect function in different application, but it is very important to choose suitable material according to the application . Below lists show up some hints help you choice right material:
- Physical properties: Melting temperature, vapor pressure, density, electrical conductivity, thermal conductivity, coefficient of thermal expansion, electron emission capability
- Mechanical properties: Strength, fracture characteristics, creep resistance and ductility
- Chemical properties: corrosion resistance, etching
- Machinability: Machining, forming, welding
-
The micro structure and the characteristics of recrystallization characteristics: The recrystallization temperature, embrittlement, aging effect
