What your materials team actually checks
Lightweight & thermally conductive
AlSi10Mg prints dense aluminium parts at roughly a third of the weight of steel, with high thermal conductivity — ideal for heat exchangers and lightweight structures. Heat-treatable (T6) for higher strength. Lot-tested.

A-Powder by AO Metal · AlSi10Mg
A-Powder AlSi10Mg is the standard aluminium alloy for laser powder bed fusion — light, thermally conductive and easy to print in thin walls and internal channels.
AlSi10Mg powder in brief
- Low weight — aluminium parts for weight-sensitive assemblies.
- Heat transfer — good thermal conductivity for heat exchangers and cooling plates.
- 20–63 µm cut — read the note below if your parameters are tuned to a finer cut.
About A-Powder. A-Powder is AO Metal’s own line of LPBF metal powders, produced in China under an ISO 9001 quality system. Additive Plus sells and supports it in the US — you order and pay here, and our materials engineer answers your questions.

Good to know before you order
This lot is a 20–63 µm cut.
A-Powder supplies this AlSi10Mg in a 20–63 µm particle-size range, slightly coarser at the top end than the common 15–53 µm cut. Most LPBF systems run it well; if your machine or parameter set is tuned to a finer cut, ask our materials engineer first.
Made in China. If your program requires US- or allied-origin material (for example DFARS-compliant supply), see our Carpenter Additive alternative or ask our engineer.
Questions about A-Powder AlSi10Mg
What is A-Powder?
