Aluminum (AlSi10Mg) is widely used in metal 3D printing due to its strength, lightweight, and good thermal properties. Unlike traditional shiny milled aluminum, 3D printed aluminum has a matte gray, slightly rough, and less clear surface. Aluminum alloy 3D printing service is quite popular in JR metal 3D printing service. The main materials are AlSi10Mg.

Why choose aluminum alloy 3D printing?
The characteristics of aluminum alloy SLM are high processability and ductility, and a good strength-to-weight ratio. Aluminum is a metal with a good strength-to-weight ratio, high thermal conductivity, high electrical conductivity, low density, and natural weather resistance.
Aluminum alloy has excellent physical, chemical, and mechanical properties, and has been widely used in many fields. However, the properties of aluminum alloys increase the difficulty of selective laser melting fabrication. Such as easy oxidation, high reflectivity, and thermal conductivity.
At present, there are still many problems in SLM forming aluminum alloys, such as oxidation, residual stress, void defects, and compactness. These problems are mainly improved and solved by strictly protecting the atmosphere, increasing the laser power, and reducing the scanning speed. At present, Al-Si-Mg alloys are the main materials for SLM-forming aluminum alloys, and the representative ones are AlSi12 and AlSi10Mg.
Al-Si 12 is a lightweight additive manufacturing metal powder with good thermal properties. AL-Si12 can be applied to thin-walled parts such as heat exchangers or other automotive parts, as well as aerospace industrial-grade prototype and production parts. The combination of silicon or magnesium makes aluminum alloys stronger and harder, making them suitable for thin-walled and complex-geometry parts, especially in applications with good thermal performance and low weight.
