Ultra-Machinable Cast Aluminum Sheets

Machine reliably flat parts for CNC routing tables, assembly jigs, and precision tasks. These sheets are cast to consistent thicknesses and won’t distort as you machine them. Even at whirring speeds, they cut precisely with minimal tool wear.

MIC6 Aluminum—Machines like butter, even better than cast 5083 aluminum. The best for large-scale jobs, MIC6 puts the least amount of strain on your tools. However, it's not as strong, corrosion resistant, or weldable.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.

Air-Permeable Mold-Quality Metapor Aluminum Sheets

Create vacuum-forming and thermoforming molds without vacuum channels or holes. The pores in Metapor aluminum evenly distribute a vacuum and release air and moisture, so bubbles and blemishes won’t form. You need to mill the aluminum to expose the pores.
