Brass and Bronze Balls for Valves and Mechanical Parts
REDHILL supplies brass and bronze balls for valves, pumps, instruments and mechanical parts. Brass combines copper and zinc, while our bronze range includes tin bronze and aluminum bronze. Each alloy offers a different balance of strength, wear resistance and corrosion resistance. Therefore, choose the material to match the fluid, load and temperature in your system.
Applications of Brass and Bronze Balls
For example, common uses include:
- Valves and Pumps: Check balls and seats for heating, dosing and fluid control systems.
- Marine Equipment: Selected bronze grades suit seawater valves and pumps. However, flow and water conditions affect alloy selection.
- Instruments and Electrical Devices: Conductive parts for contacts, switches and meters.
- Bearings and Mechanisms: Balls for selected low-load bearings, guides and moving assemblies.
Choosing the Right Alloy
Brass balls suit many general valve and electrical uses. In addition, tin bronze offers useful resistance to wear and corrosion. Selected aluminum bronze grades combine strength with corrosion resistance for marine equipment.
However, conductivity, machinability and magnetic response vary by alloy. Therefore, specify these requirements when choosing the material. Match the ball, mating parts and lubricant to the load and motion in your design.
Available Grades and Sizes
- Precision Grades: G100–G2000 options. See our precision grade guide for tolerance definitions.
- Diameters: 0.4–101.6 mm, up to 4 inches.
- Custom Requirements: Other tolerances and finishes on request.
Availability depends on the alloy, diameter and grade. Finally, send us your alloy, ball size, quantity, tolerance and working conditions. We can then confirm suitable options, lead time and worldwide delivery.
