9-4 Aluminum Bronze is a high-strength copper-based alloy known for its excellent wear resistance, corrosion resistance, and toughness. With a composition primarily of copper, aluminum, and iron, it offers a strong combination of mechanical strength and durability, making it suitable for demanding applications. It performs well in high-load and high-wear environments, particularly in marine and industrial settings where resistance to seawater, chemicals, and abrasive conditions is crucial.
The alloy maintains good dimensional stability under stress and provides low friction, reducing wear in moving parts. Common applications include bushings, bearings, gears, and valve components, as well as parts exposed to extreme conditions such as hydraulic systems and aerospace components. Its combination of high tensile strength and resistance to deformation under load makes it a preferred choice for heavy-duty applications where reliability is essential.
