Norilsk Nickel studying the prospects of using powder materials

10 august 2023

Norilsk Nickel experts conduct research in the field of powder metallurgy, which is a cost-effective alternative to machining various metal parts.

Powder metallurgy makes it possible to create products with unique properties, significantly increase the metal utilization rate and improve the competitiveness of the final product.

"Our key interest is now connected with powders made of heat-resistant alloys based on nickel and cobalt. These are high-temperature materials that are used in aviation, rocket and space technology and engine building," says Kirill Yartsev, head of the Department of Technological Innovations at Norilsk Nickel.

According to the company's press service, up to 40% of metal powders used in specialized powder metallurgy are made from alloys based on the key metals of Norilsk Nickel - nickel and cobalt.

Norilsk Nickel specialists are working on the prospects for the development of powder materials: demand for them is growing due to the intensive development of 3D printing technologies, metal injection molding, hot isostatic pressing and coating. Powders can also be used in other innovative developments of the company – from new heat-resistant alloys based on nickel and cobalt to catalytic materials.

Nickel carbonyl powder produced by the Kola Division of Norilsk Nickel is used for the development of new materials. Last year, Norilsk Nickel received the first prototypes of nickel alloy powders for use in 3D printing and hot pressing technologies. Experts have already compared the characteristics of the obtained materials and are trying them using a 3D printer.

This year, the company is considering the possibility to replenish the range of nickel alloy prototypes with powders for coating and injection molding of metals, as well as to obtain prototypes from cobalt-based alloys and stainless steel.
