Magnetic Analysis Corporation has over 85 years of experience as a leader in non-destructive testing. The company developed the first American-made system using electromagnetic principles for the detection of flaws in steel bar products. Since then, MAC has grown to become a major source of eddy current, flux leakage and ultrasonic equipment and systems for testing metals throughout the world. MAC also provides the appropriate encircling, segment or rotary eddy current test coils, rotary ultrasonic transducer assemblies, drive mechanisms, mounting benches, and automated system controls for a broad range of applications in metal manufacturing plants.    With headquarters in Elmsford, NY and additional manufacturing in Boardman, Ohio, a European plant in Őstersund, Sweden, and field engineers and experienced representatives located throughout North and Central America, Brazil, Chile, Europe, Australia, Turkey, Korea, India, and China, customers worldwide can be served.  MAC systems for detecting surface, subsurface, internal, ID and OD defects, wall thickness, ovality and eccentricity in tube and pipe; flaws, welds, and breaks in wire; and variations in alloy, heat treatment, hardness, and grade, are in use in countries throughout the world. Recent installations include flux leakage systems to inspect heavy wall tube to meet API and other specifications, and ultrasonic/eddy current billet testers.
