HSP Rolled Machined Aluminium Tooling plate is manufactured from 5083 alloy and, as you’d expect from a machined Tooling Plate, produced to extremely good dimensional tolerances, before being polycoated with 100micron plastic on both sides.

HSP is processed using a special rolling technique, then heat treated to give it very low residual stresses compared to other rolled plate and characteristics that rival those of Cast Tooling Plate. Being based on a 5083 alloy, HSP has excellent corrosion resistant properties and is ideally suited for machining and welding, and being a rolled plate means it is stronger, harder and has better impact resistance than cast plate.
