Magnetic Analysis Corporation (MAC) is a long-standing provider of non-destructive testing equipment for metals. With more than 95 years of experience, the company pioneered the first American-made system that used electromagnetic principles to detect flaws in steel bar products. It now supplies a broad range of eddy current, flux leakage, ultrasonic, and phased array ultrasonic systems for testing metals worldwide, along with encircling, segment, or rotary test coils, transducer assemblies, drive mechanisms, mounting benches, and automated system controls for metal manufacturing plants. MAC serves customers across the metal manufacturing sector who rely on reliable inspection for surface and subsurface defects, internal flaws, wall thickness, ovality, and related material variations. The company is based in Elmsford, New York, with manufacturing sites in Boardman, Ohio and Östersund, Sweden, and a network of field engineers and representatives across the Americas, Europe, Asia, and Australia.

MAC’s equipment addresses a range of needs, including detection of defects in tubes and pipes, flaws in wire, and assessments of alloying, heat treatment, hardness, and grade variations. Recent installations include flux leakage systems for heavy-wall tubes to meet API and other specifications, ultrasonic/eddy current billet testers, and an online Weld Zone Test system for large-diameter ERW tubes. The firm maintains memberships with industry bodies such as ITA, FMA, WAI, ASNT, and API. In 2026, MAC participated in Wire 2026 in Düsseldorf, Germany, reflecting its ongoing engagement with the global NDT community.
