What Magnetic Analysis Corporation does

Magnetic Analysis Corporation (MAC) is a privately held, 95-year-old (founded 1928, Long Island City, NY) manufacturer of nondestructive testing (NDT) equipment headquartered in Elmsford, NY, with 101–250 employees and manufacturing/test facilities in Boardman, OH. The company designs and builds systems across five core technology families — Eddy Current Testing (Minimac II, MultiMac II/SM, Rotomac rotaries up to 18,000 RPM), Ultrasonic Testing including phased array (Echomac FD-6/PA, 25mm UT Rotary, TacTic immersion systems), Magnetic Flux Leakage (MacFlux DC 1000/2100/3100), AC Flux Leakage (Rotoflux AC, detecting defects as small as 0.1 mm on hot-rolled bar), and electromagnetic Comparators (Varimac VI, Production Comparator VI) — used to detect surface, subsurface, internal, and dimensional flaws in metal tube, pipe, bar, wire, and parts. Customers are industrial metal manufacturers serving aerospace, oil and gas (OCTG per API 5L/5CT), automotive, medical device, and general metal-mill end markets.

MAC generates revenue through a mix of hardware sales, operating leases (active since 1934, with 81 customers retained 25+ years and bundled annual OEM calibration), ISO-accredited third-party testing services at its Boardman facility, ASNT SNT-TC-1A-conformant training, and field engineering services (installation, calibration, upgrades, remote pre-acceptance). Distribution is direct enterprise field sales with dedicated regional Business Development Managers and wholly-owned regional headquarters in Östersund, Sweden (EU HQ, acquired Contest AB in 2000), Shanghai (China & Southeast Asia), North Rocks, Australia, and Gurgaon, India, covering 25+ countries. Key strategic events include the February 2022 asset acquisition of TacTic from Laboratory Testing Inc. (expanded ultrasonic immersion product line; second-generation systems launched 2025), the November 2023 appointment of Daniel Lawrence as President and CEO, and the rollout of MultiCollector II software unifying Echomac, MultiMac, Rotoflux AC, Varimac, and Production Comparator VI on a SQL database for full product traceability.
