Why Use Sintered Metal?

  • Low Required Energy

    Sintered metal requires minimal energy to process when compared to other metalworking technologies

  • Ability to Mass Produce

    High-volume production rates of complex shapes are achievable with fewer total production steps

  • Superior Tolerances

    Precision tolerance capability is partnered with an excellent surface finish. 

  • Reduce Waste

    Less material removal and waste, faster cycle times, and longer tool life. 

  • Sustainable Green Technology

    Our material is derived from recycled metals; helping to reduce energy consumption and the demands on our natural resources.

Sintered Metal Materials

Behind every good product is great material. Our raw material feedstock combines sustainability and resource conservation to provide you with the results you need.

Using recycled metal (typically reclaimed from stamping or other metal-working processes), we produce a powder through water atomization.

Powder Metal Materials Processed
  • 300 series stainless steel
  • 400 series stainless steel
  • Copper-infiltrated iron & steel
  • Diffusion-alloyed steel
  • Hybrid low-alloy steel
  • Iron & carbon steel
  • Iron-copper & copper steel
  • Iron-nickel & nickel steel
  • Pre alloyed steel
  • Sinter-hardened steel
  • Soft-magnetic alloys
  • Custom grades not found in MPIF Standard 35

Alphaloy is an iron-based powder metal alloy that's designed and developed for hot end exhaust applications where expensive alloys are traditionally used, such as stainless steel and nickel-based materials. The alloying constituents are similar to ductile cast iron materials, meaning they retain the benefits of a ferritic microstructure.

Alphaloy allows for high-quality welding due to the absence of carbon and does not require post-welding thermal treatment like other cast alloys.

Alphaloy features superior resistance to cyclic hot oxidation and exhibits coefficient of thermal expansion properties in line with stainless steels and ductile iron. In addition, its high formability allows for unique part geometry in a variety of mechanical joint configurations.

High Strength Steels

Our sintered metal division processes a variety of pre-alloyed and admixed steel grades. We formulate material specs based on your product’s needs for wear resistance, top-notch mechanical performance, and dimensional precision. 

We specialize in heavy-duty gear applications, using a variety of combinations of pre-alloyed manganese, molybdenum, and chromium with admixed carbon, nickel, or copper. We also process a variety of gear applications using lower-alloy materials and a secondary heat-treating process.

Typical applications for these gear components include:

  • Transfer cases
  • Steering systems
  • Modular camshafts
  • Flywheels
  • Engine crank gears
Stainless Steels

We offer 400 series (ferritic) and 300 series (austenitic) grades of stainless steel powder metal parts. We combine our expertise in the processing of stainless steel with our high-temperature sintering furnaces to reach impressive mechanical properties.

Common applications for these materials include:

  • Hot and cold-end exhaust flanges
  • HEGO bosses for automotive and commercial exhaust systems
