High-Quality Aluminium Bronze Bushes | Durable & Corrosion-Resistant, high-strength, automotive bronze, heat-resistant, Flanged Bronze Bushes, Cast Bronze Bushing, Plain bushes in Mohali
Aluminium bronze bushes are a type of bearing bushing made from a copper alloy containing aluminum and other elements. They are known for their high strength, wear resistance, and corrosion resistance. This makes them ideal for a wide range of applications, including marine, automotive, and industrial.
High-Performance aluminium bronze bush are typically manufactured using a casting process. This allows for precise dimensional control and ensures that the bushes have a consistent grain structure throughout. Aluminium bronze bushes are available in a variety of sizes and shapes to meet the specific needs of different applications.
Aluminium Bronze Bearing Solutions for Maximum Wear Resistance
What Are Aluminium Bronze Bushes?
Aluminium Bronze Bushes are cylindrical components used primarily to reduce friction and wear between moving parts in machinery. Made from a copper-aluminium alloy (with optional additions like iron or nickel), these bushes are known for their high strength, corrosion resistance, and durability – especially in tough environments.
They’re commonly pressed or machined into housings or bores, where they serve as a bearing surface between shafts and other rotating parts.
