View A Video on Powder Metal Parts - A Quick Introduction

Solid metal parts that are made from powdered metal via powder metallurgy are strong equipment components used in almost every industry. They are utilized in a variety of industrial applications in the automotive, hardware, electronic, computer and lawn and garden industries.

Powder metal parts are found in automobile components, structural parts, filtration systems and magnetic assemblies. Powdered metal gears are particularly well-suited to the sintering process, as the inherent porosity of powder metal parts naturally dampens sound. Bushings and bearings are also simple to produce through this process, though their tight tolerances usually require a secondary sizing operation. Metal powder parts are a popular choice for parts with magnetic properties, as the soft magnetic material is usually difficult to form, limiting the choice of shapes. However, powder metal can be easily formed in a wide variety of shapes, and its magnetic properties are enhanced in the proper sintering atmosphere. Powdered metal parts are produced through 2 different processes-sintering and metal injection molding. Sintered metal parts, including sintered bronze parts and sintered steel parts, are made by heating metal powder below its melting point then and formed into shapes. Metal injection molding adds polymers or wax through resin impregnation to powdered metal, heats them both up until pliable, where they are then formed in a mold. Both of these processes are often used to produce aluminum powder parts, copper powder parts or iron powder parts.


Metal is formed and fabricated from powder to a finished part through a process called powder metallurgy. Metal powders are the main raw material, which is processed into powder form by pulverization, chemical reduction, electrolytic techniques, mechanical alloying, or most commonly, atomization. The resulting powder is then impregnated with a lubricant, which is added to the metal to reduce friction between the powder and the pressing dies. Next, the raw material undergoes a forming process, where it is pressed, forged or molded. A major final step in powder metallurgy is sintering, a high temperature process that develops the final properties of the metal part. The compacted raw materials, called green parts, are heated in a furnace at temperatures below their melting point to bond the particles together without changing part's shape. The sintering process also increases part strength and controls the porosity of the part. Secondary operations are not usually required, but parts may still need to be heated, sized, deburred or machined. Although the finished parts look solid, they actually consist of small interconnected capillaries, which cause the parts to be approximately 25% porous. They are sealed through steam treatment, infiltrated with a metal that has a lower melting point, or oil or plastic resin impregnation, which provides the best seal.
Sintered metal products have many benefits over parts produced through other methods. The process results in little waste, as approximately 97% of the materials are used during the procedures. Sintered products are not shape sensitive either. Powder metal part manufacturers create parts close to tolerances, often eliminating the need for secondary operations. Therefore, powder metallurgy is often the technique of choice for the production of intricate parts requiring bends, projections and depressions. A wide variety of shapes and designs can be sintered out of an almost infinite choice of alloys, composites and associated properties. Powder metal parts have controlled porosity for self-lubrication and for gas or liquid filtration.

A powder metallurgy process called metal injection molding is sometimes used to produce smaller, more complex, high density and high performance metal parts. It combines the technologies of plastic injection molding and powder metallurgy to produce parts used in the automotive, medical and dental, firearms, hardware, computer, and electronics industries. It offers more design freedom, more complex detailing, reduced assembly costs, reduced waste and denser, stronger, more corrosion resistant and magnetic products. However, only smaller, thinner parts are produced this way, and tooling costs are higher than regular powder metallurgy. There are a few main differences in metal injection molding. During the initial mixing process, the metal powder is mixed with thermoplastics in addition to lubricants. The parts are only formed through molding, which uses standard plastic injection molding machines. The thermoplastics are then removed, or debindled from the parts by thermal or chemical means through an open pore network. The parts are then sintered and put through any necessary secondary operations.

Many different metals, including aluminum, copper, brass, iron, steel and bronze, are able to convert to powdered form and undergo a type of powder metallurgy to produce parts and products. Aluminum is a popular metal to use because of its light weight, conductivity and high flammability. It's often used in pyrotechnics and high strength structural applications. Copper parts exhibit good electrical and thermal conductivity, and are used in heat sink and electrical contractor applications. Iron powder is used to make structural parts, filters and bearings. It also contains graphite additive. Steel, often stainless steel or tool steel powders, are high strength and used in automobile weight reduction. Finally, bronze powder parts are used to produce self-lubricating bearings. It is a denser metal with a higher mechanical performance than brass.

Types of Powder Metal Parts

  • Aluminum powder is a metal powder made from aluminum materials.
  • Aluminum powder parts are produced using flaked aluminum which is popular due to its ductility and light weight.
  • Copper powder parts are produced though the compaction, consolidation and heating of finely flaked copper materials.
  • Iron powder parts are popular due to the properties of the ferromagnetic metallic chemical element which is strong, highly malleable and ductile allowing for easy manufacturing. 
  • Metal injection molding, also called "MIM," is a low cost, high volume manufacturing process that produces custom metal parts near to net shape by combining the way injection molded plastics are formed with powdered metal sintering.
  • Metal powder is created through powder metallurgy and can be formed into solid components through the tool and die process.
  • Metal powder parts are produced through the compaction, consolidation and heating of various flaked metals such as aluminum, copper, bronze, nickel, brass, steel, stainless steel, nickel and titanium in order to produce a solid metal product.
  • Powder metallurgy utilizes metallic powders in the manufacture of shaped components which may be finished or semi-finished products.
  • Powdered metal is used to make solid parts from metal powder. Metal can be made into powder form using a variety of techniques, including atomization, chemical precipitation, centrifugal disintegration, and hydrogen reduction.
  • Powdered metal bearings are often self-lubricating, providing low noise level, space savings and low maintenance requirements. Lubrication is achieved through the impregnation of oil into the bearings, which aids bearing performance during rotary support of moving parts.
  • Powdered metal bushings commonly provide support to rotating axles and other shafts in engines, drive systems and other equipment. Like bearings, powdered metal bushings can be lubricated through impregnation to increase efficiency.
  • Powdered metal gears are mechanical hardware formed through various powder metallurgy techniques to transmit power, motion, speed and directional change between axes.
  • Powdered metal structural parts are particularly common in the automotive industry in exhaust, fuel and brake systems, engine parts and transmission components. Sintered parts are also found in computer and electronic equipment.
  • Resin impregnation is a secondary operation in which plastic resins are applied to compact powder metal parts in order to act as a seal and reduce porosity.
  • Sintered bronze parts are produced by heating powdered bronze to just below its melting point in order to adhere the particles together and produce a solid metal object.
  • Sintered filters contain uniform porosity, which increases functioning. In addition, sintered filters are strong, easy to clean and heat resistant.
  • Sintered metal is a solid product made by a cold forming process that presses metal powder into a coherent mass.
  • Sintered metal parts are solid products made by compressing metal powder into a coherent mass and heating the metal to just below its melting point. Sintered metals parts can be made from aluminum, copper, bronze, nickel, brass, steel, stainless steel, nickel, and titanium.
  • Sintered steel parts are solid metal components created by the controlled heating of powdered steel materials which fuse the particles together without liquefaction.
