Security Lever for Gun Industry

Finished Weight of Component : 3.5g (iron-7% nickel powder)
Density (g/cm3) : 7.70 g/cm3
Tensile Strenght (N/mm2) :
Yield Strength (=0.2% N/mm2) :

Treatment : After sintering the part is carbonitrited to improve mechanical properties
Description: The part weighs 3.5g and is made of iron-7% nickel powder which is sintered to a density of 7.70 g/cm3. This MIM component is part of a gun and replaces a part made of alloy steel by investment casting and machining because of the cost advantages of metal injection moulding.

The wall thickness near the two holes in the security lever is maintained at 0.3mm. Test firing with the MIM lever showed no change in dimensions after firing the gun 50,000 times.
