Full Density PM Process

Full Density PM

While conventional PM processing sinters parts to 82%-88% of the theoretical density, Full Density materials are carefully processed to achieve densities ranging from 97.5%-99.7% of theoretical density.

Since material properties such as elongation and yield strength are closely related to density, Full Density materials possess significantly better properties.

Full Density components are sintered in closely calibrated, high temperature vacuum furnaces using our proprietary liquid phase sintering technology. Controlling the chemistry of the Full Density alloys also dictates the small percentage of material that becomes liquid at the sintering temperature.

This liquid rapidly diffuses throughout the entire compact, closing the pores and achieving the desired densification.
