ALCA 5 Aluminium Plate

ALCA 5 aluminium plates are precision cast plates based on the AA 5083 aluminium alloy matrix, with controlled thickness, flatness and double-sided face milling. Standard plate thickness ranges from 1/4 inch (6.35 mm) to 4 inches (101.6 mm) with a uniform ±0.005 inch (±0.127 mm) thickness tolerance.

Renaissance Fittings & Piping supplies ALCA 5 aluminium plates in India with precision-milled faces, controlled flatness and dual-side PE/PVC protection. Custom mill orders can extend the plate thickness to 8 inches (203.2 mm).
