Cutting-edge atomization and
post-processing technologies

Gränges Powder Metallurgy specializes in advanced aluminium powder materials for applications like additive manufacturing and high-performance alloys. Its proprietary DISPAL^® alloys combine low thermal expansion, high stiffness, and excellent durability at a fraction of steel's weight, making them ideal for industries requiring precision and reliability. With over 30 years of expertise, Gränges delivers high-quality aluminium powders using cutting-edge atomization and post-processing technologies, tailored to customer specifications. Sustainability is integral, leveraging aluminium’s recyclability and versatility for green innovation.

Very good form stability and high stiffness

The powder metallurgical process makes the alloys solidify extremely quickly. This results in the material having an extremely fine grain and homogeneous microstructure.

The DISPAL^® material offers a higher specific stiffness than titanium alloys and steels. This combined with a high thermal conductivity and low thermal expansion gives it an exceptional form stability.

DISPAL^® has properties comparable to those of steel but at only a third of its weight. It has a thermal expansion rate comparable with steel and a resistance to wear on the same level as cast iron alloys.

Aluminium powder metallurgy

Aluminium powders have been at the core of our business for over 30 years. The inert gas atomization process yields spherical and homogeneous particles, and the state-of-the-art post-processing line ensure powders with high cleanliness and tight powder size distribution, suitable for additive manufacturing and other PM processes.
