MIC-6 Cast Aluminum Plate
The flatness specialist: stress-relieved cast plate that will not move when you machine it.

Choose it when
Choose MIC-6 for large flat plates that must stay flat: the cast, stress-relieved structure machines freely with virtually no distortion — unlike rolled 6061 plate, which can bow when one face is machined away.
Look elsewhere when
Not a structural alloy — tensile strength is roughly half of 6061-T6, and the porous cast surface limits dyed anodizing quality. Use it for plates and bases, not loaded brackets.
Compatible finishes

As-Machined
The baseline finish: straight off the machine, fastest and cheapest.

Anodizing Type II (Clear)
The standard aluminum finish: hard, clear oxide that keeps the metallic look.

Hardcoat Anodizing Type III
Wear armor for aluminum: an oxide layer as hard as tool steel.

Chromate Conversion (Alodine / Chem Film)
Corrosion protection that stays conductive — the EMI-grounding finish for aluminum.

Bead Blasting
The uniform matte look: erases tool marks, hides fingerprints, preps perfect anodizing.

Brushed Finish
The appliance-grade look: directional satin grain on panels, bezels and show faces.

Powder Coating
Baked-on polymer armor: any RAL color, outdoor-proof, the toughest cosmetic coating.

Wet Painting
Any color, any gloss, any substrate: the flexible coat for plastics and appearance prototypes.

Vibratory Tumbling
Batch deburring by the bowl-full: every edge broken, every burr gone, at volume prices.

Laser Marking
Permanent identification with zero dimensional change: serials, logos and codes burned in, not stuck on.
Typical applications
- Vacuum chucks and inspection base plates
- Semiconductor equipment platforms
- Optical breadboards and instrument bases
- Automation fixture plates
