AlSi10Mg-T6 is RapidDirect’s workhorse aluminum-silicon-magnesium alloy for SLM 3D printing. In the T6 condition it offers higher yield strength and print stability than AlSi7Mg-T6 for lightweight, complex metal components.
AlSi10Mg-T6 Aluminum in 3D Printing
AlSi10Mg-T6 is RapidDirect’s workhorse aluminum-silicon-magnesium alloy for SLM 3D printing. In the T6 condition it offers higher yield strength and print stability than AlSi7Mg-T6 for lightweight, complex metal components.
- Strength-to-weight performance: Aluminum alloys provide strength while keeping component weight low.
- Complex geometries: SLM can produce internal channels and geometries that are difficult to machine.
- T6 material properties: The listed mechanical values correspond to the T6 condition.
Selection note: As-printed aluminum surfaces are rough and commonly need post-processing such as shot blasting, CNC machining, or anodizing.
