METAL INJECTION MOLDING MATERIALS

WHICH MATERIAL IS RIGHT FOR YOU?

 

The Metal Injection Molding process starts with the selection or creation of a feedstock. ARC possesses an in depth knowledge of metallurgy and can guide you in making the best choice for your application.

 

ARC excels at producing custom mixed feedstocks of stainless-steel, cobalt and nickel-based alloys (among others) to produce metal parts with maximum strength and versatility. Our batch atmosphere furnaces deliver the most consistent stainless steel and low-carbon ferrous alloys in the industry.

 

Below is a small sampling of the broad spectrum of alloys we use at ARC. If you don’t see the alloy you want or you’d like to discuss a specialty alloy for your individual application.
