3D Printing AlSi7Mg
Description
AlSi7Mg is a widespread, heat-treatable aluminum alloy that maintains a high mass-to-strength ration with good corrosion resistance for an aluminum alloy, ideal for applications requiring a combination of excellent thermal properties with low weight. Our 3D printing AlSi10Mg is a gas atomized powder with good flowability and spread ability, formulated for laser powder bed process. It is widely used in aerospace parts, automotive parts, profile surface spraying, and powder metallurgy.
