BS 2657 is a British standard that discusses fluoroboric acid and metal fluoroborates for electroplating. The objective of BS 2657 is to provide best industry specifications for fluoroboric acid and metal fluoroborates for electroplating to achieve adequate corrosion protection of the metal substrates.
BS 2657 specifies requirements for concentrated solutions of fluoroboric acid, lead fluoroborate, stannous fluoroborate, copper fluoroborate, and zinc fluoroborate which are used for the preparation of electroplating solutions.
BS 2657 on fluoroboric acid and metal fluoroborates for electroplating is useful for:
Fluoroboric acid is a strong colourless liquid acid that can corrode both metals and tissue, and is widely used for electroplating and cleaning purposes. Fluoroborate electroplating baths have a number of unexpected benefits including wider useful current density range and improved appearance.
BS 2657 focuses on requirements of fluoroboric acid and lead, tin, copper, zinc fluoroborate, solution requirements for fluoroboric acid, and metal fluoroborates for electroplating.
Adopting best-industry requirements specified in BS 2657 for the preparation of electroplating solutions can help you improve the quality, durability and service-life of electroplated components.
