Positive Material Identification (PMI) is the identification and chemical analysis of various metal alloys through nondestructive methods. PMI can be conducted on-site or in the laboratory. PMI helps our customers choose the right materials for their application from this vast market. In production, PMI confirms through certification that the materials our customers have received are, in fact, the materials they’ve purchased. At all stages, PMI services allow clients to build successful business plans for their products and processes.
