AURUNA® 7000 Gold Iron Electrolyte

AURUNA® 7000 Gold Iron Electrolyte

High-Speed Electrolyte for Hard Gold Deposition

AURUNA® 7000 is used for depositing hard gold coatings in special high-speed equipment. The weakly acidic electrolyte has a wide operating range with easy bath maintenance and high plating speed. No oxidation of the alloy partner iron.

AURUNA® 7000 was specifically developed for the automatic high-speed gold-plating in equipment for selective plating and continuously working reel-to-reel lines. Due to vigorous electrolyte agitation (flow, spray), it allows the working at high current densities with stable long-time behaviour. It can be also operated as a gold strike electrolyte.

The deposits are solderable, low in pores, ultra-bright, hard and abrasion-resistant. They have a constantly low contact resistance. Therefore the electrolyte is excellently suitable for the gold-plating of electronic components such as connectors, contacts and edge connectors on printed circuit boards.
