Aluminium Alloy Ingots

Standard JIS, BS and AA grades in regular production, plus custom chemistries cast to your specification.

Our Range

Grades We Manufacture

We specialise exclusively in aluminium. Each grade below is produced from carefully segregated scrap and verified on our in-house spectrometer before casting. Many more grades are available on request.

ADC12
JIS H 5302 / Al-Si-Cu

The most widely used aluminium die-casting alloy.

ADC12 Aluminium Alloy Ingot

ADC12 combines excellent fluidity, pressure tightness and resistance to hot cracking with good machinability. It is the first choice for high-pressure die casting of automotive, two-wheeler and general engineering parts.

Key Properties

  • Excellent fluidity
  • Pressure tight
  • Good machinability
  • Low hot-cracking tendency

Typical Applications

  • Engine & gearbox housings
  • Two-wheeler parts
  • Electrical enclosures
  • Power tool bodies
  • General die castings
LM6
BS 1490 / Al-Si12

Eutectic alloy for thin, intricate castings.

LM6 Aluminium Alloy Ingot

LM6 has near-eutectic silicon content giving superb castability and very good resistance to corrosion, including marine atmospheres. It suits large, thin-walled and complex sand and gravity castings.

Key Properties

  • Outstanding castability
  • High corrosion resistance
  • Good ductility
  • Weldable

Typical Applications

  • Marine fittings
  • Pump bodies & impellers
  • Thin-wall housings
  • Architectural castings
  • Cookware
ADC1
JIS H 5302 / Al-Si

High-silicon die-casting alloy with superior fluidity.

Get Quote

ADC1 Aluminium Alloy Ingot

ADC1 offers excellent fluidity and corrosion resistance with lower copper than ADC12. It performs well in thin-walled, large-area die castings where filling is critical.

Key Properties

  • Very high fluidity
  • Good corrosion resistance
  • Low copper
  • Fine surface finish

Typical Applications

  • Thin-walled covers
  • Automotive brackets
  • Lighting fixtures
  • Appliance parts
A356
AA / ASTM B179 / Al-Si7Mg

Heat-treatable alloy for strength and ductility.

Get Quote

A356 Aluminium Alloy Ingot

A356 responds well to T6 heat treatment, delivering a strong balance of strength, elongation and fatigue resistance. It is the standard alloy for cast aluminium wheels and safety-critical structural castings.

Key Properties

  • Heat treatable (T6)
  • High strength & elongation
  • Good fatigue resistance
  • Low iron

Typical Applications

  • Alloy wheels
  • Suspension components
  • Aerospace & defence castings
  • Structural parts
ADC6
JIS H 5302 / Al-Mg

Corrosion resistant alloy with a bright finish.

Get Quote

ADC6 Aluminium Alloy Ingot

ADC6 is an aluminium-magnesium alloy with the best corrosion resistance in the ADC family and an attractive surface that anodises well. It is preferred for decorative and marine applications.

Key Properties

  • Excellent corrosion resistance
  • Anodises well
  • Bright surface
  • Good strength

Typical Applications

  • Marine hardware
  • Decorative parts
  • Food & dairy equipment
  • Outboard components
