Advanced powder metallurgical AlSi alloys with low CTE 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 is often referred to as the “green” metal thanks to its properties that support sustainable development. It is lightweight, strong, corrosion resistant, durable, versatile and impermeable – and also highly recyclable.
DISPAL® is a range of hyper-eutectoid AISi alloys produced by powder metallurgy. They have a dimensional stability comparable with steel and a wear resistance on the same level as cast iron alloys.
The spray-formed aluminium materials of the DISPAL® portfolio contains a high amount of Si (from 17% up to 35%). Our standard portfolio has six DISPAL® alloys that deliver outstanding results.

DISPAL® S220, and DISPAL® S260, are qualified for Additive Manufacturing by Laser Powder Bed Fusion (LPBF) to create fully dense metal parts with short lead times.
The process usually consist of a free initial assessment from a team of experts in GPM. We will collect all the necessary information to compile a case for you to draft the best action plan and connect you to the right partner depending on your geographical location and your product needs, being prototyping or serial production.
