PMI is a verification process of identifying chemical and mechanical properties of metals. Different instrumentation and testing is used to accurately determine metal properties. For quick alloy identification of materials our handheld XRF unit is used. In other situations, especially when assessing elemental composition at low levels, the ICP unit is used to evaluate samples. Often times, other characteristics of the metals are evaluated, which include tensile strength, yield strength, elongation, hardness, etc. Our team of experts work together to ensure all your testing needs are met in a timely manner
