Electroplated Steel Balls
Electroplated steel balls are made by electrochemically coating the surface of ordinary steel balls (usually made of carbon steel, mild steel, or stainless steel) with a layer of metal (such as zinc, nickel, gold, silver, or a colored coating).
Polypropylene (PP) plastic balls are spherical plastic products made from polypropylene. They are lightweight, chemically resistant, have low water absorption (<0.01%), and are resistant to both low temperatures (-30°C) and high temperatures (approximately 100°C). They are non-toxic, semi-crystalline thermoplastics commonly used in industrial, environmental, and medical applications.
AEnhances corrosion resistance (unlike uncoated carbon steel, which rusts easily), provides a polished aesthetic, and improves wear resistance (e.g., chrome plating for valves). Nickel plating also supports magnetic applications.
ASolid balls are denser for valve/check applications; hollow balls (~1 mm wall thickness) reduce weight and evaporation in tanks, with better floatation. Both may have molding seams and resist UV with additives.
APrimarily 52100 chrome alloy steel (1% carbon, 1.36% chrome), which hardens to 60–65 HRC. Other variants include high-speed tool steels, or martensitic grades for high-temperature use.
AStart with low-carbon steel or chrome alloy steel blanks, which are then electroplated with metals like nickel for shine and corrosion protection or hard chrome for hardness. The base steel is cold-headed, flashed, and heat-treated before plating.
