What is Powder Metallurgy?

Sintering in Powder Metallurgy

Powder metallurgy is a near-net-shape manufacturing process that begins with powder production, where metal powders are created through methods such as gas and water atomization. These metal powders are then prepared through blending process, a step where binders and lubricants are incorporated to improve flowability and consistency. Common iron-based PM materials include FC-0205, FD-0205, FC-0208, and FL-4205.

The mixed material next undergoes the powder compaction process in a precision die under high pressures, typically 400 to 800 MPa. Compaction defines the part’s geometry and density profile. At this stage, the compact still lacks sufficient density and strength and remains brittle in its green state, with strength characteristics similar to chalk.

The green compact is then processed through sintering process in a controlled atmosphere at temperatures below the metal’s melting point, typically around 1120 °C for iron-based alloys. Solid-state diffusion during sintering bonds the metal particles, improving density, strength, and overall structural integrity.

Sintered parts may require secondary operations to enhance dimensional accuracy, surface finish, and hardness.

Why Powder Metallurgy Needs Secondary Operations?

In powder metallurgy, secondary operations are often needed as press-and-sinter alone cannot meet the precision, surface quality, or design features required in service. Our secondary processing capabilities include:

  • Machining powder metal can achieve or better surface finish and accuracy.
  • Sizing can improve radial dimensional tolerances of sintered parts to IT5–IT8.
  • Stean treatment is a cost-effective method for corrosion protection and increased airtightness on ferrous powder metal parts.
  • Heat treatment can improve the hardness, strength, and wear resistance.
  • Tumbling improves the surface roughness of sintered parts.
  • Electroplating, such as zinc and chrome plating, can improve the corrosion resistance of powder metal parts.
  • Dacromet is an environmentally friendly surface treatment process that offers better corrosion resistance than electroplating.
  • Oil impregnation imparts self-lubricating capabilities to sintered bushings.
  • Copper infiltration fills the pores in powder metal parts, increasing their density, strength, and hardness.
  • Welding can join PM components to other PM parts or to wrought or cast metals in assemblies
Machining Powdered Metal Parts

Advantages of Powder Metallurgy

The advantages of powder metallurgy include cost-effective and eco-friendly production of near-net-shape parts with complex geometries, tight tolerances, and consistent quality, while maximizing material utilization and enabling high-volume manufacturing.

Cost-effective

Powder metallurgy is cost-effective because it generates very little waste, and supports high-volume production through automated, repeatable process.

Quality Consistency

Powder metallurgy delivers consistent part-to-part quality through repeatable pressing operations and sintering cycles across production batches.

Complex Geometry

Powder metallurgy can incorporate complex shapes like internal channels, thin walls, multiple levels, and splines directly during pressing without extensive machining.

Near Net Shape

PM forms parts in a die cavity to near-final dimensions, reducing or even eliminating the need for secondary machining, which saves both time and cost.

Tight Tolerances

The radial dimensional tolerance of sintered metal parts is generally between IT8 and IT9, and can be achieved through the sizing process to IT6 to IT7.

Environmentally Friendly

PM generates minimal waste, consumes less energy, and can utilize recycled powders, making it a more eco-friendly option than traditional metalworking processes.

Powder Metallurgy FAQs

Here are some of the most common questions we receive about powder metallurgy production. If you don’t see yours here, feel free to contact us!

Powder metallurgy is widely applied in high-volume production because tooling costs are spread over large batches, while small quantities are less economical.

In general, our MOQ starts from 1,000 pieces. Depending on the size and geometry of the part, smaller parts may require a higher MOQ, while larger parts may allow a lower MOQ

For standard powder metallurgy parts, if stock is available, we can ship within 3–5 days. If not in stock, production typically requires about 20-30 days.

For customized parts, tooling fabrication and approval are required prior to batch production, followed by mass production. The total lead time is approximately 30 days.

Our standard payment terms are 50% advance payment upon order placement, with the remaining 50% due before shipment. 

For long-term cooperation, we can reduce the advance payment to 30%.

Yes. All of our powder metallurgy parts are covered by a one-year warranty. 

If any quality issues occur within this period under normal use, we will repair or replace the parts accordingly.

Yes, we are glad to provide free samples so you can evaluate our quality with zero risk, usually up to 5 pieces. 

International courier costs, however, are to be borne by the customer.

Many parts originally produced by machining, casting, stamping, or welding can be re-engineered into powder metallurgy (PM) components. 

By doing so, you can benefit from lower material and machining costs, improved production efficiency, and greater design flexibility through near-net-shape manufacturing. 

Our engineering team has extensive experience in guiding customers through this conversion process.

Conventional metal manufacturing methods such as machining and sheet-metal stamping, material waste is typically high. Powder metallurgy, by contrast, is a near-net-shape process with material utilization rates of 95–98% and minimal secondary machining. Because of these advantages, powder metallurgy is highly cost-effective in high-volume production.

With conventional powder metallurgy, structural components made by single pressing and sintering typically reach a density of 6.6–7.2 g/cm³, while oil-impregnated bearings usually fall between 5.8–6.2 g/cm³. When the copper infiltration process is applied, sintered parts can attain a higher density of 7.2–7.6 g/cm³.
