Strength and Durability: The strength of structural powder metal components comes from selecting the appropriate metal powder and optimizing compaction and sintering strategies. This results in improved tensile and yield strength, as well as hardness.
Precision and Consistency: Powder metallurgy allows for tight tolerances, dimensional accuracy, and consistency, accommodating all production volume requirements.
Cost-Effectiveness: High material utilization makes powdered metal a cost-effective choice. Producing components to tight tolerances often eliminates or reduces the need for additional operations, saving both time and costs.
Eco-Friendly Process: Powdered metal is a green process with low energy usage and minimal scrap, making it more economical than standard machining, casting, or other metal-forming technologies.

Iron Powder: The most commonly used material for structural applications. It can be used alone or combined with alloying materials like carbon, copper, nickel, and molybdenum to enhance mechanical properties.

Carbon Steel: Made from a mixture of iron and graphite powders. During sintering, graphite is absorbed into the iron, producing a steel structure. Prealloyed carbon steel is also available for specific applications.
Copper Steel: Produced by adding copper powder to iron powder, resulting in improved strength and hardness.
Nickel Steel: Adding nickel (with or without copper) to iron powder creates high-strength components with favorable fatigue strength.
Other Additives: Infiltration of lower melting materials like copper can increase density and impact resistance. Adding small amounts of phosphorus enhances electromagnetic properties, ductility, and strength.

Low Alloy Steels and Diffusion-Alloyed Steels: Made from prealloyed steel powders using nickel, molybdenum, and manganese. These are used when high performance and hardenability are required.

Electromagnetic Materials: Used when components require good permeability, purity, and density.

Stainless Steel Powder Metals: Required for applications needing significant mechanical properties and high corrosion resistance.

Copper Base Materials: Include pure copper, brass, bronze, and nickel silver. Each is selected for characteristics like electrical or thermal conductivity, oil impregnation, machinability, ductility, or corrosion resistance.

Aluminum Powders: Offer good corrosion resistance, excellent finishing properties, high strength-to-weight ratios, and vibration and sound-damping features.
