R·G-7000 (OPAL 7000) Alkaline Zinc-Nickel Alloy Process is a high-end alkaline alloy electroplating solution with ultra-high corrosion resistance and stable plating performance. It forms a uniform, dense, and light opalescent zinc-nickel alloy coating, featuring excellent throwing power, outstanding burning resistance, and good workpiece deformability. Far superior to conventional single zinc plating processes in environmental adaptability, it can replace traditional cadmium plating, meeting high-standard industrial anti-corrosion and mechanical performance requirements.
This process is primarily applied to high-demand metal components in harsh corrosive environments. In the automotive industry, it is specially designed for new energy vehicle battery tray fasteners, chassis structural parts, brake system fittings, and high-strength automobile fasteners, providing long-term anti-rust and anti-corrosion protection against road salt, high humidity, and alternating temperature environments. For aerospace and defense industries, it suits precision structural hardware and standard parts, delivering stable sacrificial protection and reliable mechanical properties for mission-critical components.
In marine, coastal and heavy industrial fields, it is ideal for hydraulic valve fittings, pneumatic components, outdoor heavy-duty mechanical parts and coastal engineering metal accessories. The dense alloy coating effectively resists salt fog, atmospheric erosion and chemical corrosion. Additionally, the process supports rack mass production with stable nickel content distribution, low brightener consumption and high yield rate, perfectly adapting to high-precision and high-reliability batch manufacturing requirements of industrial parts.
A1: R·G-7000 alkaline zinc-nickel alloy process achieves 5–10 times higher corrosion resistance than conventional alkaline zinc plating, with the coating resisting white rust for over 500 hours and red rust for up to 1000 hours in salt spray tests. It adopts a stable alloy deposition formula with uniform nickel distribution across all current density ranges, excellent throwing power and burning resistance, which perfectly covers complex-shaped workpieces and deep-hole parts. Different from ordinary zinc plating, this process eliminates hydrogen embrittlement risks, retains excellent workpiece deformability, and can serve as an eco-friendly substitute for toxic cadmium plating. It also features low additive consumption and stable process operation, balancing superior anti-corrosion performance and mass production efficiency.
A2: The R·G-7000 (OPAL 7000) process is mainly applicable to batch rack plating production of high-reliability metal workpieces requiring ultra-strong corrosion resistance, especially for high-standard industrial parts in harsh environments. The core applicable workpieces include new energy vehicle core structural fasteners, automotive brake and fuel system fittings, aerospace precision components, defense standard hardware, marine and coastal engineering metal parts, as well as hydraulic and pneumatic industrial fittings. It stably supports high-current-density production, delivers consistent opalescent coating appearance and stable mechanical properties for finished products, and is compatible with multiple passivation and sealing post-treatments to further enhance environmental durability of parts.
