Gränges invests in post-processing line for aluminium Additive Manufacturing powders
Gränges Powder Metallurgy SAS, based in Saint-Avold, France, has invested in a new post-processing line used in the production of aluminium powders for Additive Manufacturing. The post-processing line includes ATEX classified sieving, homogenising and packing equipment in a closed workspace to ensure the highest safety and cleanliness. The new line is planned to be fully operational in the first quarter 2025.
Gränges Powder Metallurgy has been producing high-performance Powder Metallurgy aluminium alloys by inert gas atomisation for over thirty years. The company is mainly known for the Dispal range of low-thermal expansion AlSi alloys, commonly used in the semi-conductor and precision optics industries. As well as Dispal, standard AlSi10Mg powder and customer-specific aluminium alloys are also produced.
“The investment is a step in our ambition to become a leading producer of aluminium AM powders. With the investment, Gränges can supply large quantities of homogeneous, spherical aluminium powders with sharp powder size cuts and processed under inert gas,” said Peter Vikner, Managing Director, Gränges Powder Metallurgy. “The dedication to aluminium alloys guarantees cleanliness from cross contamination with other alloys. It also enables synergies in raw material purchase, in processing and in R&D, ensuring that we have the right capacity, price and quality for the market.”
Gränges Powder Metallurgy is a part of the Gränges Group, an organisation dedicated to aluminium with a total net sales in 2023 of 22,518 MSEK and an operating profit of 1,576 MSEK (€1.92 billions and €135 million, respectively). The plant in Saint-Avold in France is dedicated to aluminium powder production and spray forming with a total capacity of 3,500 metric tonnes per year.
