The MIM process uses a wide array of alloys and metals. From stainless steel to tungsten alloy to low alloy steel, and more, MPP provides expertise in working with any material used in the MIM process. MIM is an excellent alternative to other forming processes, including Inconel casting for aerospace manufacturing.
The most commonly used elements in MIM processing are:
Iron and nickel are two of the easiest elements to process because of their compatible melt temperature and ease of sintering. Iron and nickel make up a significant amount of the total tonnage produced in the industry.
