About aluminium ingots and billets
Primary aluminium ingot is cast from smelter metal and remelted by foundries, rolling mills and extruders. A7 and P1020 both refer to a minimum of 99.7% aluminium, with limits on iron and silicon. Extrusion billets are alloyed logs, usually 6063 or 6061, cast to diameter and cut to length for extrusion presses.
We confirm the smelter or title holder, the brand and the availability, and agree inspection at loading, before an offer goes to a buyer.
Frequently asked questions
What is the difference between A7 and P1020?
Both are primary aluminium of at least 99.7% purity. A7 is the Chinese standard designation; P1020 is the common international designation, with slightly tighter iron and silicon limits.
How much aluminium fits in a container?
Usually around 25 tonnes in a 20ft container, depending on bundle weight and weight limits.
Do you supply extrusion billets?
Yes. We supply 6063 and 6061 extrusion billets, with diameter and cut length to order. Send us the alloy, temper requirements, size and volume.
How is aluminium priced?
Against the LME aluminium price for the quotation period, plus an agreed premium for the origin, brand and delivery point.
