What Are Powder Metallurgy Products?
Powder metallurgy (PM) products are manufactured from metal powders through the powder metallurgy forming process using a variety of ferrous and non-ferrous materials. Metal powders are metal alloys processed into extremely fine powders by atomization. The metal powder is then compressed using a compactor and custom-designed tooling to form a near-net-shape part.
Once the part is compacted to the required specifications, the part is sintered to achieve the final material specifications, including hardness, tensile strength and density. Powder metallurgy products (sometimes called powdered metal parts) are used in a wide variety of applications; ranges include automotive and off-highway vehicles, industrial and household appliances, firearms and sporting goods.
Advantages of Powder Metallurgy Products
When you choose custom powder metallurgy products, you will get:
Versatility: from simple shapes to complex parts with precise geometries.
Cost-Effective: Powder metallurgy products are very cost-effective, especially for the production of high-volume parts.
Material utilization rate: The waste of powder metallurgy products is the least in the production process, thus improving the material utilization efficiency.
Consistency and uniformity: Powder metallurgy products have consistency, which is especially important for applications requiring high levels of reliability and performance.
Custom Compositions: Powder metallurgy products allow the mixing of different metal powders to create custom compositions with desired properties.
Reduced need for post-processing: In many cases, powder metallurgy products require little post-processing, reducing overall production time and costs.
What Are the Common Powder Metallurgy Products?
Materials Used in Powder Metallurgy Products
1. Metal Powders
The primary raw materials in powder metallurgy are metal powders. These powders are finely ground particles of metals such as iron, steel, aluminum, copper, nickel, titanium, tungsten, and others. The choice of metal powder depends on the desired properties of the final product.
2. Alloy Powders
Besides individual metal powders, alloy powders can also be used in powder metallurgy. Alloying different metals allows manufacturers to tailor the properties of the final product, enhancing characteristics like strength, corrosion resistance, and heat resistance.
3. Lubricants
In the powder metallurgy process, lubricants are added to the metal powders to facilitate their movement and prevent agglomeration during compaction. Common lubricants include zinc stearate, magnesium stearate, and other organic materials.
4. Binders
Binders are necessary for holding the metal powders together during the compacting phase before sintering. The binders are typically organic materials like polyvinyl alcohol (PVA) or wax-based materials.
5. Sintering Aids
Sintering is the process where compacted metal powders are heated to high temperatures to fuse the particles together. Sintering aids, such as copper or nickel, are often added to improve the densification and mechanical properties of the final product.
6. Fluxes
Fluxes help to reduce oxides on the metal surfaces during sintering, ensuring better fusion between particles and preventing defects in the final product.
7. Impregnation Materials
In some applications, powder metallurgy products may undergo impregnation with secondary materials to enhance specific properties, such as self-lubrication or increased porosity.
8. Graphite
Graphite is used as a mold material for the powder metallurgy process, particularly in the production of complex-shaped products.
