EOS Aluminum AlSi10Mg DMSL on EOS M 300-4
Categories:	Metal; 3D Printing/Additive Manufacturing Metal; Nonferrous Metal; Aluminum Alloy
Material Notes:	Parts made of EOS Aluminum AlSi10Mg are characterized by having good strength and hardness as well as having high dynamic load bearing capacity. Main Characteristics: High productivity process produces very good results Parts can be machined, wire eroded, electrical discharge machined, welded, micro blasted, polished and coated Chemical composition corresponding to DIN EN 1706 (EN AC 43000) Typical Applications: Casted parts Those needing the combination of good thermal properties and low weight Heat Treatment: Solution annealing of 30 minutes in 530 °C followed by immediate quenching to water. Artificial aging of 6 hours in 165 °C followed by cooling in air. The porosity could increase due to the heat treatment. Information provided by EOS GmbH (Electro Optical Systems).
