Abstract
Alpha-beta Brass article has a surface consisting of an almost non-porous layer with a thickness of at least 0.025 mm composed of alpha-phase and produced by thermal evaporation of zinc from the surface. The alpha-beta brass contains a corrosion inhibitor, pref. arsenic. The articles have an improved resistance to zinc loss, esp. when contacted with water.
