Aluminium Alloys — Lightweight Components for Demanding Applications
We source aluminium castings in a comprehensive range of alloys, optimised for strength, corrosion resistance, machinability and thermal conductivity. Aluminium is the material of choice for weight-critical applications across the automotive, aerospace, electronics and industrial sectors.
Why aluminium?
Aluminium alloys offer an exceptional combination of low weight, high strength-to-weight ratio, excellent corrosion resistance and good thermal conductivity. This makes them ideal for a wide range of structural and functional applications.
Common aluminium casting alloys
AlSi alloys (4000 series)
Silicon-rich alloys with excellent castability and good corrosion resistance. Widely used for die castings and sand castings.
- AlSi7Mg (A356) — high strength, heat treatable
- AlSi9Cu3 (A380) — general purpose die casting
- AlSi12 (A413) — excellent fluidity, pressure-tight
AlCu alloys (2000 series)
Copper-containing alloys with high mechanical strength. Commonly used in aerospace and structural applications.
AlMg alloys (5000 series)
Magnesium-containing alloys with excellent corrosion resistance, particularly in marine environments.
Casting methods for aluminium
- Sand casting — flexible, suitable for prototypes and medium volumes
- Die casting (HPDC/LPDC) — high volumes, excellent surface finish
- Investment casting — complex geometries, tight tolerances
- Gravity die casting — good mechanical properties, medium volumes
Post-processing
We offer complete post-processing services including CNC machining, heat treatment (T6, T7), anodising, powder coating, painting and assembly.
