Why GKN Additive Materials?

Digital Powder

We strongly believe that a digital twin will enable serial production in additive manufacturing. This not only helps to save time by having a robust process prediction; it also means a better understanding of the process, which is a great starting point for further cost reduction.

Global Partnerships

We collaborate with world class customers and technology partners like HP, EOS and VW to provide high quality metal AM powders.

Full Scale Production

We are prepared to meet the growing demand for AM materials with our state-of-the-art powder production facilities based in the USA.

Technology Expertise

Our dedicated team of material experts provides full support with world leading AM powder laboratories including testing capabilities and metallography.

Global Distribution

Benefit from our global footprint, that enables worldwide distribution with local warehouses, dedicated customer service and technical sales support.

How we deliver value to our customers

The quality of the material supplier has a huge influence in the benefits, companies get from Metal 3D printing. High quality parts begin with high quality material.

GKN Additive Materials helps customers from automotive, aerospace, medical and industrial markets, who require metal powders tailored for low to high volume AM processes (Binder, Laser, DED).

With our fully controlled value-added finishing process we constantly refine our superior portfolio of advanced digital powders for AM including low alloy steels, stainless steels, nickel-, copper-, aluminum-, titanium-alloy powders, and specialized novel powders.

Powder Development

Material technology is a critical success factor for the future mass adoption of Metal 3D Printing. Knowing how powder behaves during the entire production process helps to support machine parameters and understanding the finished component properties.

Physical Properties

Powder tailored to AM processes by optimizing properties such as flow rate, apparent density and particle size distribution through atomizing and processing techniques.

Mechanical Properties

In-house testing capabilities for AM printed bars for measuring tensile properties after each step in the process. Additional testing methods used for full characterization of mechanical behavior of AM materials.

Metallography

World-class metallography experts image and analyze powder for shape and morphology as well as internal microstructures of printed specimen to correlate the effects of AM processes on material properties.

Chemical Composition

ASTM standardized methods are used to certify the chemistry of AM powder including oxygen, nitrogen, hydrogen, carbon and sulfur. Materials are guaranteed to a specification or grade.

Powder Morphology

Depending on the atomization technique, powders can have various shapes and morphology features, nominally ranging from very irregular to very spherical with minimal satellites.

Printing Studies

The Innovation Center is equipped with laser and binder AM systems utilized specifically for materials development projects with customers.

Atomization Techniques

GKN Additive Materials provides atomized metal powder for high quality and precision AM solutions. Custom alloys are available in all processing techniques upon request.

Water Inert Gas Electrode Induction (EIGA)

Method uses low- and high-pressure water to atomize very irregular powder/ typically used for press & sinter
High solidification rate yielding irregular powder
Most suitable for less reactive metals - steel, stainless, copper
High scalability (several hundred thousand tons per year)
Higher throughput & lower cost

Materials: SS, Fe alloys
