The typical powder metallurgy process includes powder production, mixing, compaction, and sintering.
Powder production is the first step in PM. It’s no exaggeration to say that the characteristics of the powders determine the quality of the final components.
Common powder production methods including gas atomization, water atomization, reduction, electrolysis, and mechanical grinding.
Metal powder (usually iron-based alloy) is mixed with a binder like zinc stearate or lithium stearate. These binders help the powder flow, enhance compressibility, and reduce the force required to eject the compacted part from the die.
Common powder metallurgy materials include: FC–0205, FD-0205, FC-0208, and FL-4205.
Mixed metal powder is compacted in a precision die at 400–800 MPa to form the green compact. This compaction process defines the part’s basic geometry, including profiles and dimensions.
Although compaction increases bulk density and forms the part, the green compact has low strength and remains fragile at this stage.
The green compact is sintered in a controlled atmosphere at a temperature below the metal’s melting point.
For iron-based materials, the typical sintering temperature is 1120 °C. During sintering, solid-state diffusion bonds the metal particles, enhancing mechanical properties and structural integrity.
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:
Powder metallurgy offers cost-effective, 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.
Powder metallurgy is cost-effective because it generates very little waste, and supports high-volume production through automated, repeatable process.
Powder metallurgy delivers consistent part-to-part quality through repeatable pressing operations and sintering cycles across production batches.
Powder metallurgy can incorporate complex shapes like internal channels, thin walls, multiple levels, and splines directly during pressing without extensive machining.
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.
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.
PM generates minimal waste, consumes less energy, and can utilize recycled powders, making it a more eco-friendly option than traditional metalworking processes.
BLUE is dedicated to enhancing your powder metallurgy parts across a variety of applications, including automobiles, motorcycles, aerospace, medical fields, powder tools, household appliances, etc.

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.
