2020-1-1 · Zinc is a main constituent of copper-nickel-zinc alloys (previously ‘nickel silver’ or German silver), which are dealt with in a special DKI information booklet. In contrast, the zinc content of Cu-Ni alloys is restricted to 1% max. Zinc-free alloys are required as materials for fittings in electron tubes to avoid zinc vaporisation.

Phosphate Conversion Coatings | Products Finishing

Calcium-modified zinc phosphate. Calcium-modified zinc phosphate is typically used as a base for paint or other organic coatings. The calcium co-deposits with zinc and acts as a built-in grain refiner to form a smooth microcrystalline structure. Coating weights are typically in the range of 150–500 mg/ft2, which allows for enhanced adhesion
