gold bronze pigment powder

Gold Bronze Pigments are metallic pigments produced from copper-zinc alloy (brass) through mechanical milling and surface chemical treatment. The alloy composition and milling process determine the final color tone — from pale gold through rich bronze to reddish copper — and the surface treatment improves oxidation resistance compared to untreated brass powder. Available from 200 mesh to 1500 mesh, they are used in decorative paints, printing inks, plastics, and specialty coatings where a warm metallic gold appearance is required.
