AURUNA® 5100 Pure Gold Electrolyte

Pure gold coatings with very good bonding and soldering properties

AURUNA® 5100 is a neutral fine gold electrolyte for depositing matt, lemon-yellow coatings. It’s specifically developed for applications requiring excellent bonding and soldering properties.

In addition to good ductility, the layers from AURUNA® 5100 also exhibit a low hardness and a low contact resistance. Even under production conditions, the layers have a high gold purity of 99.99 wt. % Au.

The coatings meet the requirements of ASTM B488-01, Type III, Code A/B.
