Iron

Iron: Powdered Metal Parts and Components

CMT produces components from a wide variety of powder metal iron and steel alloys, which are generally known as ferrous powder metal alloys, or ferrous sintered metal alloys.

These include admixed elemental ferrous alloys, diffusion alloyed steels, pre-alloyed low alloy steels, stainless steels, and tool steels.

Admixed, Elemental Ferrous Alloys

Pure Fe can be used for soft magnetic and low strength structural applications. When Fe is admixed with C, Cu, Ni, P, or Si, and processed by powder metallurgy, the result is carbon, copper, nickel, phosphorus, or silicon steels. These steels are used for structural and/or soft magnetic applications. Powder metallurgy permits processing of alloys with chemistries that are very difficult to process by other metalworking technologies.

Diffusion Alloyed Steels

  • Pure Fe is typically partially pre-alloyed (“diffusion alloyed”) with Ni, Cu, and Mo.
  • Graphite (C) is subsequently admixed with the resulting diffusion alloyed steel powder to produce the required C level in the final product. Also, other elemental powder may be admixed at this stage.
  • Diffusion alloyed steels offer the benefits of a soft Fe core, for compressibility, together with alloying elements that are partially sintered/diffused into the core.
  • Diffusion alloyed steels are typically used in medium to high strength structural applications.
  • Strength and wear resistance can be further enhanced by heat treating these steels.
  • MPIF STD 35 material designation is FD.

Prealloyed Low Alloy Steels

  • Typically, Fe is fully alloyed with Ni, Mo, Cu and/or Mn. Each powder particle has the same alloy chemistry.
  • Graphite (C) is subsequently admixed with the prealloyed powder. Other elemental powders may also be added at this stage.
  • Prealloyed low alloy steels are used in high strength structural applications.
  • Strength and wear resistance can be further enhanced by heat treatment.
  • Some of these steels can be sinter-hardened.
  • MPIF STD 35 material designations are FL, FLN, FLN2, FLN4, FLN6 and FLNC.

Metal Injection Molding

Metal Injection Molding (MIM): Parts and Components

Metal Injection Molding (MIM) is a process that combines the benefits and unique material possibilities of metal powder processing and the shape complexity possible with plastic injection molding.

In this process spherical or semi-rounded metal powder is combined with a melted thermoplastic binder, extruded and cooled to form feedstock pellets which are then used in a plastic injection molding machine to form complex shapes. Also MIM parts have superior mechanical and corrosion properties compared to conventional powdered metal parts. Many unique and/or difficult to process materials (using conventional manufacturing techniques such as machining) are possible with Metal Injection Molding without an increased level of difficulty. Examples include materials such as tungsten carbide, tungsten heavy alloys, other refractory materials, and tool steels. In parts where extensive machining would have been used, especially when combined with costly materials or high hardness can realize significant cost savings over machining due to the net shape or near net shape forming process possible with injection molding.
