AlSi7Mg Aluminium Metal Powder

AlSi7Mg – is the common aluminium Al-Si alloy with good casting properties showing high performance during powder bed fusion.
The alloy offers good strength and better ductility than for AlSi10Mg alloy. Printed samples and parts can be annealed or water quenched for various applications.
The properties are equal or superior to traditional casting A356 type alloys.
As-sintered parts can be treated in a similar manner as for casted parts
