H62 Brass Solid Balls Bearings Balls Industrial Precision Dia 1mm-60mm All Sizes

Measure the seat bore diameter of your valve or bearing race with calipers. The ball diameter should match the seat specification — typically the ball is sized to create a positive seal or a defined clearance fit. If you have a fractional-inch specification (e.g., 3/8"), select the equivalent metric size (9.525mm). When in doubt, contact us with your application details and we can help confirm the correct size.

H62 brass has a tensile strength of approximately 330–420 MPa and is commonly used in low-to-medium pressure valve applications (typically up to 10–16 bar depending on valve design). For high-pressure systems above these thresholds, or for applications requiring hardened steel or stainless steel balls, please confirm your pressure rating and consult your valve manufacturer's specification before ordering.

H62 is a standard brass alloy composed of approximately 60–63% copper and the remainder zinc. It offers good machinability, moderate strength, and reliable corrosion resistance in water and oil environments. Compared to H59 (lower copper content, slightly harder), H62 provides better corrosion resistance. Compared to H68 or H70 (higher copper), H62 is more cost-effective while maintaining adequate mechanical properties for most valve and bearing ball applications.

Brass naturally develops a patina (surface oxidation) when exposed to air over time, which does not affect mechanical performance. In water and oil environments, H62 brass resists corrosion well. However, brass is not suitable for contact with strong acids, ammonia-based compounds, or highly alkaline solutions, which can cause dezincification or stress corrosion cracking. For aggressive chemical environments, stainless steel or ceramic balls may be more appropriate.

H62 brass contains lead in trace amounts depending on the specific batch composition, and standard brass alloys may not meet NSF/ANSI 61 or food-grade certifications without specific testing. If your application involves potable water or food contact, please contact us to confirm material certification before ordering. For certified food-grade applications, stainless steel balls are typically the safer choice.

Pack quantities are set based on typical usage patterns for each diameter. Small diameters (1mm–4mm) are available in 50-piece packs, suitable for batch assembly or repair work. Mid-range diameters (4.5mm–12.7mm) come in 10-piece packs. Larger diameters (15mm–19.05mm) are available in 5- or 2-piece packs, and diameters 20mm and above are sold individually. If you need a custom quantity, contact us before placing your order.
