Powder Metallurgy materials
Our material capabilities in PM
When it comes to unique product solutions, selecting the ideal material plays an important role.
GKN Powder Metallurgy materials provide options to reduce weight or size, create high wear capabilities and improve thermal conductivity. To find the appropriate powder metal solution, we offer suitable materials for each of our process technologies. Because of this, GKN Powder Metallurgy offers full-service solutions for the Automotive and Industrial markets.
Conventional PM materials
We provide the broadest material selection in the industry to meet a wide range of needs:
- Low- and High-Alloy Steels
- Stainless Steel
- Special Alloys
Our PM materials are engineered to your needs and tailored to your applications. Our PM process technologies match from lower to full density and tight dimensional tolerances.
As a full metal solution provider we adapt and apply as per customer application needs, such as strength, ductility and wear-resistance.
With our advanced specialty alloys and processing techniques, GKN PM component solutions often exceed industry performance standards.
Metal Injection Moulding materials
Alloy steels, stainless steels, and heat resistant materials are among the choices delivered by MIM technology. MIM processing delivers material performance similar to wrought products due to densities approaching 98 percent of theoretical values. Alloy steels, stainless steels, and heat resistant alloys are common choices that GKN supplies.
The binder agent controls the flow properties of the materials more than the powdered metal. This allows relief-like structures and engravings, such as company logos or identification marks to be produced in detail on a part. The use of high strength alloys, corrosion resistant and other premium steels are possible as the type or amount of binder will allow proper flow to product quality parts with detailed features.
MIM technology provides a process for design engineers and product designers to develop creative solutions. This is because powder metals can make custom alloys easily, and in any batch size needed for prototyping to mass production. In addition, the MIM process works well for complex geometries when compared to the time and cost associated with other traditional processes like milling or casting.
