A Comparison of Electroless and Electrolytic Nickel
Most EN systems operate between 180–190°F, offering a natural evaporator system. Spray rinsing over EN helps keep chelated nickel from the waste stream while minimizing staining. The EN process operates at a comparatively low metal content, which facilitates recapture of the nickel and reduces overall waste generation. Typical electroless nickel systems operate at less than 1 oz/gal nickel
