Aluminium ingot grades
| Grade | What it means |
|---|---|
| P1020A | LME high-grade primary aluminium, Al99.70 equivalent. The main traded primary grade. |
| Al99.70 (A7) | Chinese primary grade under GB/T 1196, often called A7. |
| ADC12 | JIS die-casting alloy (Si 9.6–12.0%, Cu 1.5–3.5%) for engine and gearbox castings. |
| A356.2 | High-purity AlSi7Mg casting ingot (Si 6.5–7.5%, Mg 0.30–0.45%) for wheels and structural castings. |
Packaging
| Format | Configuration |
|---|---|
| Strapped bundles | Stacked ingots strapped into bundles of about 1 tonne. |
| Bundle marking | Brand, grade, lot number and bundle weight. |
| Lot size | Exchange-traded primary metal is dealt in 25-tonne lots; other lot sizes by agreement. |
Applications
Remelting, rolling and extrusion billet production, die casting and alloy manufacture.
Frequently asked questions
Is P1020A the same as 99.7% aluminium?
P1020A is a primary grade with a 99.70% aluminium basis and limits on silicon, iron and other elements. The full limits matter, not just the headline figure.
Can secondary alloy replace primary ingot?
No. Alloys such as ADC12 contain deliberate silicon and copper additions and are used for casting, not where pure aluminium is required.
What is the minimum order quantity?
It depends on the product and the lot. The minimum quantity, price and delivery terms are set out in the written quotation.
