Die casting alloys
Aluminum, zinc or magnesium: choosing the alloy
We review the part and recommend the alloy and the process: high pressure die casting, or gravity or sand casting where the part needs heat treatment or thick sections.
AlAluminum Die Casting
A380 · ADC12 · A360
Light and a good conductor of heat. Housings, heat sinks, enclosures and brackets.

Which metals can be die cast?
Mainly aluminum, zinc and magnesium alloys. Aluminum and larger magnesium parts are cast on cold chamber machines, zinc on hot chamber machines.
Do you make the die and the castings?
Yes. We design and build the die, run trials and supply castings, machined and finished as required.
What files do you need for a quotation?
A 3D model (STEP or IGES), a 2D drawing with tolerances, the alloy, the annual volume and any machining, finishing or testing requirements.
Do you review the design before quoting?
Yes. We check wall thickness, draft, radii, undercuts, gating and machining datums, and send DFM comments with the quotation.
Aluminum or zinc: which should I choose?
Aluminum for lighter and larger parts and for heat sinks; zinc for small, detailed parts with close dimensions and plated finishes.
