Product Description

CuZn25Al6Fe3Mn4, also known as C86300, is a type of graphite bronze alloy that is commonly used as a material for bushing slider washers and other sliding components. This alloy offers a unique combination of properties that make it suitable for a wide range of applications.
The addition of graphite particles in CuZn25Al6Fe3Mn4 bronze provides excellent self-lubricating properties. Graphite is a natural lubricant that reduces friction and wear between sliding surfaces. This allows the bushing slider washers made from this alloy to operate smoothly and efficiently, even under high loads and speeds.
In addition to its self-lubricating properties, CuZn25Al6Fe3Mn4 bronze also possesses high strength and good corrosion resistance. The alloy's copper-zinc base provides good ductility and toughness, while the addition of aluminum, iron, and manganese improves its mechanical properties and corrosion resistance. This makes the alloy suitable for use in harsh environments and demanding applications.
CuZn25Al6Fe3Mn4 bronze bushing slider washers are often used in mechanical systems that require smooth and reliable sliding motion. They are commonly found in automotive transmissions, industrial machinery, and other applications where precise alignment and smooth operation are critical.
The alloy's machinability is also a key advantage, as it can be easily cut and shaped to meet specific application requirements. This allows manufacturers to produce precision-fitted bushing slider washers that ensure optimal performance and reliability.
In summary, CuZn25Al6Fe3Mn4 C86300 graphite bronze is an excellent material choice for bushing slider washers and other sliding components. Its self-lubricating properties, high strength, good corrosion resistance, and machinability make it suitable for a wide range of applications where smooth and reliable sliding motion is essential.
