The 50mm steel balls from Feicheng City Dongdafeng Steel Ball Factory are precision-ground components made from Chrome Steel GCr15, equivalent to AISI 52100, a high-carbon alloy known for its wear resistance and durability. These balls meet precision grades between G10 and G1000, ensuring tight tolerances for roundness, diameter, and surface finish. The listing also includes 30mm copper spheres, which complement the steel balls for applications requiring non-ferrous properties.
Chrome Steel GCr15 offers a typical hardness of 60-66 HRC after heat treatment, with a standard density of 7.85 g/cm³. The steel balls are manufactured to typical surface roughness of Ra 0.05 - 0.2 µm, while copper spheres usually adhere to a standard purity of 99.9% Cu. Both materials are finished to minimize defects, ensuring consistent performance in high-stress environments such as bearings, valves, or grinding media.
These components serve industries like automotive, machinery, and mining, where precision and material integrity are critical. Buyers typically source them in bulk for OEM assemblies or replacement parts, with packaging in reinforced cartons or drums for containerized shipping. The factory’s location in Shandong, China, positions it for efficient logistics to global markets, particularly for buyers requiring large volumes of standardized or custom-sized spheres.

Sourcing 50mm Steel Ball 30mm Copper Sphere from Feicheng City Dongdafeng Steel Ball Factory - China Import Guide
Before ordering, verify the precision grade and material composition to ensure they match your application’s requirements. Confirm whether the supplier can provide third-party inspection reports or certificates for critical properties like hardness, roundness, and surface finish. This is particularly important for high-precision uses such as aerospace or medical devices.
Discuss logistics terms, including Incoterms (e.g., FOB or CIF) and lead times, as these can vary based on order volume and current production schedules. The supplier’s location in Shandong may influence shipping costs and transit times, especially for buyers in Asia or Europe. Clarify whether the packaging meets export standards for moisture and impact resistance.
Request quality checks, such as dimensional inspections and material testing, either from the supplier or a third-party agency. For copper spheres, confirm the exact purity percentage and whether additional treatments (e.g., annealing) are applied. Ensure all documentation, including material test reports and packing lists, is provided before shipment to avoid delays at customs.
