When a loose or corroded ball causes a valve to leak, a bearing to seize, or a craft project to stall, finding the exact diameter you need — fast — is the real challenge. These H62 solid precision brass balls are stocked in 35 sizes from 0.9 mm (0.035 in) to 45 mm (1.772 in), giving engineers, machinists, plumbers, and makers a single reliable source for the right ball every time.
Each ball is machined from H62 brass alloy — a copper-zinc composition that delivers a smooth, bright surface finish with consistent roundness across the full diameter range. Sizes span 0.9 mm to 45 mm (approximately 0.035 in to 1.772 in), and quantity options range from 1 piece up to 100 pieces per order to suit both prototyping and production runs.
Typical applications include ball valve seats and check-valve assemblies requiring corrosion-resistant sealing balls, precision bearing races in light-load rotary mechanisms, decorative metalwork and jewelry fabrication calling for solid copper-tone spheres, and educational or STEM projects needing accurately sized metal balls for physics demonstrations.

Measure the seat bore diameter of your valve with a caliper. The replacement ball should match the nominal seat diameter — typically the ball is slightly larger than the port opening to create a seal. Refer to your valve's service manual for the specified ball diameter, then select the matching size from the variant options above.
These are fully solid brass balls throughout. They are not hollow, which makes them suitable for applications that involve compression loads, such as valve seats and bearing races where a hollow ball could deform under pressure.
H62 brass offers significantly better corrosion resistance than carbon steel in water, mild acids, and humid environments. It does not rust, making it a practical choice for plumbing valves, marine fittings, and outdoor decorative applications. For highly acidic or chloride-rich environments, verify chemical compatibility before use.
Brass balls can be used in light-load bearing applications, but they are softer than hardened steel bearing balls. They are well-suited for low-speed, low-load rotary mechanisms, decorative bearings, and educational models. For high-speed or heavy-load precision bearings, consult your bearing specification to confirm material suitability.
Yes. Those sizes correspond to common imperial fractions: 3.175 mm = 1/8", 6.35 mm = 1/4", 9.525 mm = 3/8", 12.7 mm = 1/2", 15.875 mm = 5/8", and 25.4 mm = 1". These are stocked specifically to serve both metric and imperial applications without requiring conversion.
For a single valve or bearing repair, the 1-piece or 3-piece options let you order exactly what you need. For workshop stock or small batch production, the 10, 50, or 100-piece quantities offer better per-unit value. Select your size first, then choose the quantity that matches your project scale from the QTY option above.
Yes. The polished bright brass finish gives these balls an attractive copper-gold appearance that works well in jewelry making, kinetic sculpture, steampunk fabrication, and decorative hardware. The wide size range — from 0.9 mm micro balls up to 45 mm large spheres — covers most decorative and craft requirements.
