Jinnge's anti corrosion brake discs employ a multi-layer protection system to withstand harsh environments. The base material is ductile iron (QT400-18), which itself has better corrosion resistance than gray cast iron. This is combined with a zinc-nickel alloy plating (8-10μm thickness) that offers 1,500 hours of salt spray resistance. An additional topcoat of silicon-based anti-rust paint further prevents oxidation. The coating is heat-cured to maintain integrity at 300°C, ensuring it does not affect braking performance. These discs are ideal for vehicles used in coastal areas, cold regions with road salt, or industrial zones with high humidity, extending service life by 3-5 years compared to uncoated discs.
