To Be your reliable alloy solution supplier
3J40
High hardness, high strength, non-magnetic, corrosion-resistant and high elastic alloy 3J40 is a precipitation-reinforced nickel-base alloy. It has good plasticity and is easy to be processed in the solid solution state. After cold working at large strain rate and aging treatment, it has high mechanical and elastic properties. The alloy can also be strengthened after solution and aging. 3J40 is a Ni-Cr-Al alloy with a chromium content of up to 40% and excellent corrosion resistance. 3J40 is mainly used for manufacturing bearings and shaft tips used in aviation, navigation, anti-aircraft guns and other fields.
