PowderRange® AlSi10Mg is ideal for components requiring a combination of lightweight, complex geometries with good thermal properties. The combined silicon and magnesium for this alloy offers increased strength and hardness with the flexibility for the material to be spark-eroded, welded, micro shot-peened, polished, and coated if required. Conventionally cast components are heat treated to improve the mechanical properties, for example using the T6 cycle of solution annealing, quenching, and age hardening. This can also be used after the additive build. PowderRange® AlSi10Mg has excellent weldability in laser additive manufacturing processes.

The mechanical and physical properties of any additively-manufactured

material are strongly dependent on the processing conditions used to

produce the final part. Significantly differing properties can be obtained by

utilizing different equipment, different process parameters, different build

rates and different geometries. The properties listed are intended as a

guide only and should not be used as design data.

The information and data presented herein are typical or average values

and are not a guarantee of maximum or minimum values. Applications

specifically suggested for material described herein are made solely for the

purpose of illustration to enable the reader to make his/her own evaluation

and are not intended as warranties, either express or implied, of fitness for

these or other purposes. There is no representation that the recipient of
