Umicore introduced Auruna 8000, a nickel- and cobalt-free gold-iron high-speed electrolyte engineered for sustainable hard gold plating in high-speed and brush plating applications. The weakly acidic process produces low-porosity, wear-resistant coatings with approximately 99.7 wt.% gold and 0.3 wt.% iron, achieving hardness of about 130HV and meeting ASTM B-488-01 Type I, Code C specifications for demanding technical uses. Operating at 45–65°C with a pH range of 4.2–4.6, supports plating speeds of approximately 8µm/min and metal content from 2–30g/l (nominal 12g/l).
