Tool Plate
Nox Metals stocks cast aluminum tool and jig plate, a precision ground and stress relieved plate used for tooling, fixtures, and jigs. This is a direct alternative to MIC-6 and other cast tool plate products. Available in thicknesses from 0.25 inches to 4 inches.
Cast tool plate is a cast (not wrought) aluminum plate that is precision ground flat on both sides and stress relieved for dimensional stability. Unlike wrought alloys such as 6061 or 7075, cast tool plate starts as a large casting that is then ground to precise flatness tolerances.
The stress relieving process removes internal stresses from the casting, which means the plate stays flat after machining. This is the key advantage over wrought plate for fixturing and tooling applications where dimensional stability after material removal is critical.
Cast tool plate is the standard material for CNC fixture bases, vacuum chucks, and any application where a flat, stable aluminum plate is needed as a reference surface or workholding platform.

MIC-6 is a brand name for cast aluminum tool plate made by Alcoa (now Arconic). It is precision ground and stress relieved for dimensional stability. Nox stocks equivalent cast tool plate with the same properties.
Cast tool and jig plate is typically a 5000-series aluminum casting alloy (often Alca Plus or similar). It is not a wrought alloy like 6061 or 7075.
Cast tool plate is precision ground to a flatness tolerance of approximately +/-0.005 inches per foot. This makes it suitable for fixture bases and vacuum chucks where flatness is critical.
