Nickel 500 Alloy Details
Nickel K500 is a nickel based copper alloy (63% Ni, 33% Cu) with additions of aluminium and titanium, which enables the alloy to be precipitation hardened.
This alloy has similar corrosion resistance to Nickel 400 but has the added advantage of much higher mechanical strength and hardness while maintaining good ductility and impact strength.
The increased strength comes from the fine precipitation of Ni3 (TiAl) particles throughout the solid solution substructure, during the aging part of the heat treatment process.
The alloy has the added advantage of low magnetic permeability properties down to low temperatures -150ºF (-101ºc) which makes it a valuable alloy for the application of instruments working at sub zero temperatures.
Its resistant to stress corrosion cracking gives this alloy a wide range of potential application in chemical and salt-water environments.
Nickel K500 has high fatigue strength in seawater and is resistant to impingement attack, which makes it ideal for propellers, shafts and fasteners.
The alloy can be used in non-oxidising chloride solutions and is resistant to de-aerated hydrochloric and hydrofluoric acids.
It is not recommended in oxidising acids such as nitric and ammonia containing systems, due to the copper content of the alloy.
