CZ106

CZ106 is a brass alloy with outstanding resistance to dezincification and notable cold working properties, characterized by a pure α-structure. This alloy is specifically chosen for use in applications involving warm, acidic waters. Additionally, CZ106 proves to be a suitable choice for various cold working processes such as coining, riveting, crimping, flanging, cold extrusion, and more.
