Outokumpu expands into aerospace with stainless steel powder for 3D printing. The company supports circular manufacturing, high-performance alloys, and innovative aerospace applications.

Outokumpu has stepped into aerospace additive manufacturing with a new stainless steel powder. In 2023, the business made its initial foray into the metal powder industry. It has now supplied the aerospace and aviation sector with its first commercial batch in May 2025.

This powder supports a heat exchange component that was 3D manufactured in partnership with industry partners. The design is presently being validated through prototypes. Outokumpu wants to provide powder grades that aren’t currently on the market to high-tech companies.

“We are thrilled to introduce our powder solutions into the aerospace industry,” stated Marten Franz, Head of Metal Powder Business. “New powder recipes are our main emphasis. Our 3D printing partners handle the manufacture of parts for end users. 

This powdered stainless steel has unique alloy additions and is austenitic. It offers a highly effective alternative to nickel-based alloys. It is intended for quicker development cycles and small-scale manufacturing.

Outokumpu also produces metal powders for use in other sectors of the economy. The business is creating powders devoid of nickel for jewellery and medical equipment. Additionally, it is creating heat-resistant alloys for power plants and turbines.

One essential tool for sustainable industries is additive manufacturing. Outokumpu aims to create a robust ecosystem for advanced manufacturing. It believes cross-industry partnerships will drive innovation and circularity in 3D printing.
