Materials / Die Casting
Die casting alloys
Alloy choice sets wall thickness, finish quality and tool life — we pick it with the part geometry, not after it.
Alloys we cast
ADC12 / A380 aluminium
General purpose
The default die casting alloy — good castability, strength and cost for housings and covers.
A360 aluminium
Corrosion resistance
Better ductility and corrosion performance for outdoor and marine-facing parts.
A413 aluminium
Pressure tight
Excellent castability for thin walls and pressure-tight enclosures.
Zamak 3 zinc
Fine detail
Thin walls, crisp detail and an excellent base for plating and painting.
Zamak 5 zinc
Higher strength
Zamak 3 with added copper for greater strength and hardness.
ZA-8 zinc
Bearing loads
Higher aluminium content for improved strength and wear performance.
Wall thickness and finishing
Aluminium castings typically run 2–4 mm walls; zinc can go thinner, down to around 1 mm, which is why it suits detailed decorative parts. Uniform thickness matters more than absolute thickness — abrupt changes cause porosity and sink.
Castings can be trimmed, machined on critical faces, tumbled, shot blasted, powder coated, anodised (aluminium) or plated (zinc).
