SAE 863 Sintered Iron-Copper Alloy
Our SAE 863 sintered iron-copper alloy material is produced through powder metallurgy, a specialized metal sintering manufacturing process that creates sintered metal components with excellent mechanical properties, wear resistance, and longevity.
What is SAE 863 Oil Impregnation?
Oil impregnation is the process by which the product is vacuum-impregnated with the lubricant of your choice. The lubricant is then metered from the bearing to the shaft during rotation. This is where sintered materials are known for their smooth action and self-lubricating properties, made possible by controlled pore size and total porosity within the sintered components, allowing oil to act as a solid lubricant during operation. Due to these features, sintered iron and other sintered materials are widely used across various industries, including the automotive industry, where they are commonly specified for automotive components, engine components, and transmission parts that demand strict performance requirements.
SAE 863 sintered iron-copper offers unparalleled cost-effectiveness, versatility, wear resistance, and durability compared to cast iron products. Sintered iron, produced from carefully controlled iron powder — often atomized iron powder — with specific particle size, powder composition, and alloying elements, typically includes an 18–22% copper balance. This engineered chemical composition, rooted in materials science, allows the base material to achieve superior wear performance. This combination enhances key physical properties, including tensile strength, impact energy, and overall structural integrity, resulting in durable components with enhanced properties compared to traditional cast materialsSAE 863 sintered iron-copper’s properties allow for high dimensional accuracy, enabling the production of complex shapes and complex geometries that closely match the desired shape, without machining a solid mass or solid piece of metal. Our cored bar and solid bars are offered in a huge range of sizes within virtually any size range.
The Sintering Process
SAE 863 components are formed by compacting a green compact under high pressure, then heating it through a controlled metal sintering process. During sintering, powder particles bond at a specific sintering temperature in a controlled atmosphere, forming strong sintered necks while avoiding excessive grain growth that could compromise strength.
