C250 Aluminium Cast Machined Tooling Plate

 

 

C250 is manufactured from a 5083 type alloy, and is machined to industry standard thickness and flatness tolerances and polycoated both sides. Special casting and heat treatment techniques makes this plate extremely stress free whilst retaining 85 -90% of the strength of rolled plate. It will retain its flatness and dimensional tolerances after machining or even after repeated heating and cooling. Like rolled 5083, C250 has excellent machining, welding and anodising properties. However, we recommend that you do not etch prior to anodising as this adversely affects the grain structure on the surface of the plate.
