Aluminium Alloys
The grades behind every casting we pour.
A reference guide to the aluminium alloys we work with most — chemical composition, mechanical properties, casting suitability and where each grade fits best, per BS 1490:1988.
Grade Reference
Choose the right alloy for your part.
Every drawing has a grade already specified, or a set of requirements that points to one. Here's how our three most-used alloys compare.
Not Sure Which Grade?
Send your drawing — we'll confirm the right alloy.
If your drawing doesn't specify a grade, or you'd like a second opinion on castability, cost, or mechanical performance, our team will review it and recommend the alloy that fits.
