Copper Balls exhibit good corrosion resistance in environments where fuel oil, gasoline, kerosene, and alcohol are present. Copper balls provide excellent resistance to corrosion by water. Copper also exhibits excellent electrical conductivity and widely used in the security and appliance industries for dip and tilt switches. Copper balls are available in a range of sizes, tolerances and grades of copper. Copper balls can come in useful in devices when electrical conductivity is needed. Copper balls are also much cheaper than ceramic balls but both have their own unique properties that make them useful for specific tasks.

• Corrosion Resistance: Ideal for wet, chemical, or outdoor environments; prevents rust unlike carbon steel.
• Durability: High hardness reduces wear; low torque for smooth operation and vibration neutralization.
• Hygiene and Cleanliness: Non-magnetic, easy to clean; recommended for food-grade or medical applications.
• Versatility: Omnidirectional movement with a low profile; available in dishwasher-safe variants for pet bowls (a niche use).

Common grades include:

• Main Ball: 420 stainless steel for durability and hardness.
• Cover/Retainer: 304 stainless steel for corrosion resistance.
• Cup/Housing: 410 stainless steel for strength; carbon steel housings are available for non-corrosive needs. Alternatives like 201 or 301 stainless steel are used for cost-sensitive applications, while nylon or carbon steel options exist for lighter loads.

• Material Handling: Used in ball transfer tables, turntables, cargo rolling decks, and air cargo systems for omnidirectional load movement (e.g., European air cargo containers).
• Polishing and Grinding: Ideal for milling media in hardware polishing, especially for irregular or anomalous workpieces; removes burrs and achieves smooth finishes in metal processing.
• Other Uses: Conveyor systems, sorting platforms, and lifting equipment; stainless steel variants excel in corrosive environments like food processing or outdoor settings.

A stainless steel flying saucer ball is a compact, disc-shaped bearing or grinding media made primarily from corrosion-resistant stainless steel (e.g., grades 304, 410, or 420). It functions as a ball transfer unit for smooth, multi-directional movement in conveyors or as polishing media for hardware surfaces. The "flying saucer" name comes from its UFO-like profile, allowing it to recess into surfaces for flush installation.
