Product Overview

Aluminium Bronze Balls are copper-based bronze alloy balls engineered for demanding mechanical duty where strength, hardness, and corrosion resistance must coexist in one component. Engineered and tested across thousands of installations in industrial programs, these balls are a trusted choice for customers who need reliable performance in seawater and salt-solution environments while maintaining excellent mechanical properties.

This product is supplied in the passivated condition, supporting stable surface behavior and consistent performance in real-world assemblies. Aluminium bronze balls offer excellent corrosion resistance in seawater conditions, perform well in hot, concentrated caustic solutions and salt solutions, and resist exposure to acetic acid, dry ammonia, sodium carbonate, phosphates, bromide, and chloride solutions. These corrosion and media-resistance characteristics make them a strong fit for fluid-handling systems and electrical and aesthetic applications where both durability and appearance matter.

Backed by Shandong SDBALLS Industry Co., LTD, a professional ball manufacturer with more than 30 years of production experience, SDBALLS supplies aluminium bronze balls with strict process control, flexible OEM and ODM capability, and ontime delivery planning. With two factories, more than 200 sets of modern production equipment, annual ball production exceeding 5,000 tons, and products exported to more than 50 countries, SDBALLS supports global procurement teams with stable quality and dependable supply continuity.
