HARDNESS TESTING

Hardness is the measurement of how resistant a material is to a permanent change in shape.  The hardness of a material is dependent on many different physical properties like ductility, strength, and toughness.  EPI-MTG has experience performing hardness testing on a wide range of alloys, as well as plastic, rubber, and ceramic/carbide.  EPI-MTG has the ability to perform hardness testing using the Knoop (HK), Vickers (HV), Rockwell (HRA, HRB, HRC, HRD, and HRE), and Brinell (BHN) hardness scales.
