| Magnetic Analysis Corp (MAC), USA, a leader in the development and production of non-destructive testing equipment for metal products, is celebrating its 75th Anniversary in 2003. Established in 1928, the company has evolved from a small business into a global provider of state-of-the-art eddy-current, ultrasonic and flux leakage instruments and systems.
First founded to develop several patents for using electromagnetic techniques to test steel bars for defects, the company then introduced six years later the first successful electromagnetic non-destructive tester to identify cracks in steel bars. Further development led to MAC�s introduction of the first commercial eddy-current tester in the USA in 1953. The new eddy-current technology measured the material�s conductivity instead of permeability, resulting in more reliable detection of short defects, and a greater range of test products, including copper, aluminium and stainless steel, as well as carbon steel. By 1959, MAC�s development of the Rotomac�, the world�s first rotary spinning probe eddy-current tester, allowed the detection of long continuous defects in wire and rod. In subsequent years, the company introduced the Rotoflux� flux leakage testers for ferrous metal, Varimac� eddy-current comparator to detect alloy and physical characteristics in metal parts, the ERIC line of solid state pulsed eddy-current encircling and sector coil testers, and the Echomac� line of rotary ultrasonic inspection systems.
Beginning in 1963, Magnetic Analysis expanded overseas, establishing subsidiaries in the UK, Italy and Australia. Today, with an additional subsidiary in Sweden, representing office in China and experienced representatives in Korea, India, Mexico and Brazil, the company maintains a world-wide presence. Today, MAC�s product line includes a range of test systems using different test technologies to test tube, bar, wire and related products. A skilled research and development department, working with MAC�s own experienced field engineers, continues to develop the highest level of test systems as new technologies and applications evolve.
