MIC-6 Cast Aluminum Plate

MIC-6 · ASTM B632 (Alcoa MIC-6)

Precision-cast tooling plate, stress-relieved and machined flat both sides (±0.005″). The choice for fixture plates, optical breadboards, and machine bases. Cast structure — no bending.

Working with MIC-6 Cast Aluminum Plate

Notes for the selected gauge
Values marked † are derived from our V-die geometry (die contact width) rather than measured on the brake: hole/cutout distance = the die contact region from the bend line; Z-bend spacing = minimum flange + material thickness + inside radius (45° offsets add the die lean-over). The ACB Laser minimum leg applies when optical angle measurement is required on your bend. Shorter flanges bend fine, measured with standard methods. All bend data is air-bend reference in inches. We verify on a test bend before production runs.
Corner relief is part-specific. Open Corner relief for recommendations and PDF example photos for the selected gauge. Seam gap, relief-opening size and distance from a bend line are separate dimensions; confirm the flat pattern and forming sequence.
Hardware hole sizes and part numbers are our own catalog figures. Hole sizes differ between PEM series, so don't cross them with another shop's chart. The mounting hole tolerance the clinch depends on is ±0.002″. Countersink fits require at least 0.010″ of material land under the cone; anything less leaves a knife edge that burrs and never seats square. Tap drills shown are the standard shop pick (75% thread inch, D−pitch metric); dial the percentage to your material on the tap & clearance drill chart.

Material properties

Reference values for the alloy family

Compare grades in the metal density chart when estimating weight. For strength specifications, read yield strength vs tensile strength before choosing a design value.

Mechanical & physical

Reference values per the listed specification. A basis for design comparison, not guaranteed minimums for certification work. Material certs available on request.

Alloying constituentsProducer controlled

Use the manufacturer’s product documentation and the applicable material record for chemistry. Do not substitute a wrought 6061 or 7075 recipe.

Only selected constituents are shown. Weight percent is mass fraction × 100. “Balance” is the remainder after all other elements; ranges and maximum limits are not amounts to add together.
