Typical MIM Properties

Tensile properties of MIM products are well documented. Typical room temperature tensile properties for the common compositions are compiled below and a second table shows the typical strength of some ceramic products. Ductile alloys are characterized by yield strength, ultimate tensile strength, fracture elongation, and hardness (given as Vickers hardness number VHN, Rockwell B or C HRB or HRC). Generally the densities are close to those reported in standard handbooks. Heat treatments (HT) provide a means to adjust the properties and hot isostatic pressing (HIP) is occasionally used to reach full density. Considerable variation is possible in these cycles, so only one example is listed, typically the cycle giving the highest hardness. Not all suppliers support all of these materials but the array of MIM materials and properties are quite broad.
