Gränges Powder Metallurgy

Learn About Our Principal, Gränges Powder Metallurgy

Gränges is a global leader in aluminum engineering, manufacturing and innovation.

Aluminum alloys can be produced through multiple processes, but one particularly innovative method of manufacturing is spray forming. Spray forming is a powder metallurgical process in which liquid metal droplets are sprayed and deposited in a layer-by-layer fashion onto a substrate where they rapidly solidify and form a near-net-shape preform. It is inherently simpler than other technologies and significantly more time- and cost-effective. It helps remove macrosegregation and reduce microsegregation, two issues that require extensive treatment and processing in conventional casting methods. It also provides rapid cooling and solidification of the sprayed particles, even with a significant amount of alloying elements we reach a homogeneous microstructure.
