Aluminum MIC-6-Cast Plate 1" thick Retail Price

About MIC-6|Alcoa’s (now Arconic) brand name for cast aluminum jig plate, made from a 7xxx-series alloy. The critical property is dimensional stability — virtually no residual stress means it stays flat when you machine it. Comes precision ground on both sides to ±.005” thickness tolerance, ready to go straight into the fixture. The standard for vacuum plates, checking fixtures, jigs, molds, and any tooling plate where flatness matters more than raw strength. Machines consistently with small, uniform chips. Compare to ATP-5 (5083-based cast plate, different manufacturer, similar performance) and 6061 plate (cheaper but will warp during heavy hogouts).
