AlSi10Mg Aluminum Alloy Powder
Aluminum Alloy Powders · Metal Additive Manufacturing Powder
AlSi10Mg is the most established aluminum alloy for laser powder bed fusion, chosen for lightweight structural parts in automotive, aerospace and consumer products. Its near-eutectic Al-Si composition gives excellent printability: wide process window, low hot-cracking tendency and good surface finish at high productivity. As-built AlSi10Mg typically delivers 300 MPa UTS and 230 MPa YS with 6% elongation; T6-like ageing trades some strength for up to 10% elongation. Gas-atomized powder in 20-63 µm is the most common cut; 15-45 µm is preferred for fine features. Because aluminum powder is light and reactive, suppliers must provide inert-gas packaging and controlled moisture exposure. When comparing AlSi10Mg quotes, check silicon content (9-11%), magnesium (0.2-0.45%) and powder morphology — spherical, satellite-free powder improves powder-bed spreadability and part density.

Frequently Asked Questions
How much does AlSi10Mg powder cost?
AlSi10Mg AM powder typically quotes between $45 and $90 per kg — one of the most economical alloys by volume. Submit a request here and verified suppliers respond within 24 hours.
What heat treatment is used for AlSi10Mg parts?
As-built parts are commonly stress-relieved at 300°C for 2 hours; a T6-like treatment (solution + ageing) raises elongation to ~10% at some loss of strength. Choose based on whether strength or ductility matters most.
Which particle size is best for AlSi10Mg?
20-63 µm is the standard cut for high-productivity LPBF; 15-45 µm improves fine-feature resolution. For binder jetting, coarser cuts around 20-50 µm with good flowability are typical.
Is AlSi10Mg strong enough to replace machined aluminum?
As-built AlSi10Mg (300 MPa UTS) exceeds common cast aluminum (A356/A360) and approaches 6061-T6 levels (310 MPa), making it suitable for brackets, housings and heat-transfer parts.
How should I store AlSi10Mg powder?
Store sealed in a dry, inert atmosphere; aluminum powder oxidizes and absorbs moisture, which degrades flow and print quality. Professional suppliers ship in vacuum-sealed or argon-flushed containers.
