M-5 Aluminum Plate

Designed for use in low volume to production injection molds, structural foam, semi-conductor, rotational molds, blow molds, foundry tooling along with vacuum tools. Also used in rubber molds, heating and cooling plates.


M-5 Aluminum Plate is a proven and widely used aluminum mold alloy.  Created to help prototype and low volume production mold makers produce molds more quickly, M-5 Aluminum Plate has an established track record of success.  Produced in California at an aerospace certified casting facility, M-5 Aluminum Plate provides an affordable alternative to typical wrought and forged large aluminum blocks.

M-5 Aluminum Plate offers the mold maker a porosity free and grain free product, with consistent hardness and strength properties throughout the thickness of the plate, even up to its maximum thickness of 30 inches.  The proprietary alloy composition of M-5 Aluminum Plate provides strength at room temperature, as well as increased resistance to thermal fatigue compared with some wrought alloys.

M-5 is a much more corrosion resistant alloy than typical mold materials, and can also be anodized, coated, and textured for varying mold applications.  M-5 is produced on the plus side of the stated thickness, and comes with a milled top and bottom surface to reduce handling and machining steps needed with other 5000 series mold plate products.  With its excellent dimensional stability and ready availability, M-5 is an excellent choice for many mold applications.

M-5 is available from 1 to 30 inches thick, 88 inches wide, and 195 inches in length.
