Galvanized steel balls: The surface is white or bluish-white, low cost and good corrosion resistance, suitable for slingshot steel balls and industrial grinding balls. The zinc layer is soft, has poor wear resistance, and is not resistant to high temperatures or strong acid and alkali environments.The zinc layer is soft, has poor wear resistance, and is not resistant to high temperatures or strong acid and alkali environments.
Nickel-plated steel balls: Silvery-white, mirror-like luster, high hardness, and excellent corrosion resistance make them suitable for precision bearings and valve seals. This process is environmentally friendly but more expensive, making it suitable for harsh environments.
Silver-plated steel balls: Bright silver with a high luster, excellent conductivity, and antibacterial properties, suitable for high-end electronics and medical devices. The silver layer easily sulfides and turns black, and its wear resistance is poor, requiring protection.
Copper-plated steel balls: Reddish copper luster, excellent conductivity, and affordable, are commonly used for decoration and electrical connectors. They easily oxidize to form a patina, but have poor corrosion resistance and are often used as a base coating.
Changzhou Risheng Steel Ball Co., Ltd. is located on the eastern shore of Taihu Lake, adjacent to Shanghai, with convenient transportation. Since its establishment in June 1995, the company has been dedicated to developing and manufacturing steel balls, integrating research and development with trade.
For many years, Risheng building on the foundation of the Wujin Metal Ball Research Institute, has been committed to researching steel ball manufacturing technology. We primarily produce shaft steel balls (AISI 52100), stainless steel balls (AISI 201/304/316/420/440/430), and carbon steel balls (AISI 1015/1045/1085) with diameters ranging from 0.8mm to 25.4mm, with precision grades up to G10, G40, and G100. We also offer custom specifications for alloy steel balls, military steel balls, copper balls, UFO balls, ceramic balls, and other metal balls.
High-strength inner packaging: Shockproof foam bags or custom plastic boxes are used to secure each Electroplated steel ball in place, protecting it from impacts and scratches.
Moisture-proof protection: A moisture-proofing agent is added to effectively prevent the impact of moisture on the product during transportation.
Sturdy outer packaging: Thickened corrugated cardboard boxes or wooden pallets (for large orders) are used to ensure safe long-distance transportation.
Clear labeling: Product specifications, quantity, and drop warnings are clearly marked on the outer packaging box for easy verification and safe handling.
