Aluminium Precision Cast Plates

Renaissance Fittings & Piping supplies aluminium precision cast plates in India for CNC machining, tooling, moulds, jigs, fixtures and dimensional-critical fabrication. The range covers 5000-series cast plates such as ALCA 5 / ACP 5080 and 7000-series cast plates such as MIC6, with precision-milled surfaces and controlled thickness and flatness tolerances.

Standard plate thickness ranges from 5.0 mm to 100.0 mm, with standard plate dimensions of 1270 × 2570 mm, 1570 × 3070 mm and 1570 × 3670 mm. Thickness tolerance is ±0.10 mm, while flatness is controlled between ≤0.13 mm and 0.40 mm, depending on plate thickness.

Precision Cast Plate Material Grades

The precision cast plate range covers two principal material families used for machining and tooling applications: 5000-series magnesium-based cast plates and 7000-series zinc-based cast plates.

5000-Series Precision Cast Plates

The 5000-series family is based on EN AW-5083 / AlMg4.5Mn0.7 and includes commercial designations such as ALCA 5, ACP 5080, G.AL C250 and ATP-5. The supplied reference data lists tensile strength of 240–290 MPa, yield strength of 110–130 MPa and hardness of 70–74 HBW.

For grade-specific specifications, see ALCA 5 aluminium plate supplier for the dedicated ALCA 5 product range.

7000-Series Precision Cast Plates

The 7000-series family uses a modified AlZnMgCu matrix and includes commercial designations such as MIC6, ACP 7000 and G.AL C330. The reference data lists tensile strength of 165–241 MPa, yield strength of 105–138 MPa and hardness of 65–68 HBW.

For the specific MIC6 grade, see MIC6 aluminium plates supplier in India for detailed product specifications and supply information.

The final plate size should be specified together with thickness, tolerance and required surface condition when requesting a quotation.

Precision Cast Plate Surface Finish

Precision cast plates are milled on both faces to achieve the specified surface condition.

Surface Parameter Specification
Surface Finish Ra 0.40–0.80 µm
Milling Precision milled, both faces
Protection PE/PVC protective masking on both sides

The protective masking helps preserve the machined plate surfaces during handling and transportation.

Precision Cast Plate Standards and Tolerances

Requirement Applicable Standard
Chemical Composition EN 573-3
Aluminium Plate Tolerances EN 485-3
Precision Cast Plate Tolerance Reference DIN SPEC 91529

These standards are relevant when specifying the material chemistry and dimensional control for precision cast plate procurement.

Aluminium Precision Cast Plate Grade Equivalents

Casting Alloy Class Base Material Code Standard Alloy Designation Commercial Equivalents
5000-Series Cast EN AW-5083 / AlMg4.5Mn0.7 AA 5083 ALCA 5, ACP 5080, G.AL C250, ATP-5
