ALLOY PROPERTIES

Thermally hardened Cu, Ni, and SI alloy
Excellent bending both hot and cold
Hight strenght and hardness using a treatment
good frictional properties and good resistance to wear
Excellent electrical and thermal conductivity


NB :

Usually shipped as hardened bars.
Otherwise : Advice for hardening treatment : thermal treatment at 800°C - duration 20 minutes then cooled in water re-heated at 450°C - duration 3 hours then air cooling.
