SHIMs are dense ceramic materials produced by force SHS-pressing
technology. In comparison with alloys produced by powder metallurgy, the
SHS materials possess perfect structure and increased purity and strength.
Several brands of SHIM with various physical and mechanical properties
have been developed (See in table)
