Tensile properties of representative MIM alloys
The following table shows typical room temperature tensile properties of representative metal injection molding alloys.
HT = heat treated
HIP = hot isostatically pressed
Density is % alloy theoretical density
Note: Data given is only representative of the properties attainable using MIM, since differences in impurity levels, grain size, porosity, and post-sintering heat treatment can have dramatic effects.
