In short: AlSi7Mg belongs to the aluminium-silicon-magnesium casting alloy family (A356/A357-like). With lower silicon than AlSi10Mg it can offer higher ductility after heat treatment and is used for lightweight structural 3D printed parts.
Typical applications
- Aerospace structural brackets
- Automotive lightweight parts
- Housings and enclosures

Particle size and compatible processes
The standard cut is 15–53 µm, suitable for laser powder bed fusion (LPBF / SLM / DMLS) machines. Coarser cuts for DED/LMD processes can be requested. Share your machine model and layer thickness and we will confirm the right cut and batch documents together.
Frequently asked questions
When is AlSi7Mg chosen instead of AlSi10Mg?
When higher elongation and impact resistance are required, or when equivalence to cast A356/A357 is sought.
AlSi7Mg powder price: what does it depend on?
The price depends on order quantity (kg), particle size cut, packaging (argon-filled cans or bottles), required documents (certificate of analysis, PSD report) and lead time. For a current price, state the quantity and your machine model in the quote form.
Which documents come with the order?
A certificate of analysis with chemical composition, particle size distribution (D10/D50/D90), flow and density values can be requested for each batch. Additional documents for aerospace, medical or dental projects are confirmed at the quotation stage.
