High hardness and strength, light weight and corrosion resistance. Also, being solderable, good biocompatibility (medical equipment), and strong surface decorability.
Stainless steel
Corrosion resistance, better surface finish
Carbon steel
The most common material, moderately hardness and strength, but poor corrosion resistance; could be hardened for higher strength and more brittle
Plastic
Lightweight and corrosion resistant, but limited to low strength and low load
Copper alloy
High strength and wear resistance, low magnetism
Brass
Good electrical conductivity, corrosion resistance, low magnetism
Aluminum alloy
Lightweight, easy to process, good electrical and thermal conductivity, corrosion resistance
Material treatment
Heat treatment
Method for improving mechanical strength, ductility and toughness with the help of high temperature
Dehydrogenation
Method for avoiding delayed fracture of high-strength materials under stress
