Non-Ferrous Metal Balls for Valves and Instruments
REDHILL supplies non-ferrous metal balls in aluminum, copper, brass, bronze, titanium and selected nickel-based alloys. Each material offers a different balance of weight, strength and corrosion resistance. Therefore, choose the alloy to match the fluid, temperature and load in your system.
Applications of Non-Ferrous Metal Balls
- Valves and pumps: Check balls for flow control and dosing systems. For example, suitable alloys serve in water, heating and fuel equipment.
- Marine and offshore: Selected bronze and copper-nickel alloys suit parts in seawater systems. However, the grade must match the water quality and flow conditions.
- Instruments and electrical devices: Copper balls provide conductivity for contacts and other electrical parts. In addition, selected materials offer low magnetic response.
- Aerospace and mechanisms: Aluminum and titanium balls reduce moving mass compared with steel. As a result, they suit selected motion systems and linkages.
Choosing the Right Material
For low weight, consider aluminum or titanium. By comparison, copper offers high electrical and thermal conductivity. In addition, brass and bronze balls provide options for valves and mechanical parts.
Corrosion resistance depends on the alloy and service conditions. Magnetic properties also vary, especially among nickel-based grades. Therefore, include any specific chemical or magnetic requirements with your inquiry.
Grades, Sizes and Finishes
- Grade options: G100–G2000, with availability and tolerances confirmed for the chosen alloy and size.
- Diameter range: 1/16–4 in (approximately 1.59–101.6 mm), depending on material and specification.
- Custom options: Non-standard diameters, tolerances and surface finishes on request.
See our precision grade guide for tolerance details. Finally, send us your alloy, ball diameter, quantity, finish and working conditions. We confirm availability, lead time and worldwide shipping with your quote.
