Manganese bronzes (numbers C86100 to CS5800) are actually high-tensile yellow brass that contain 22 to 38% zinc with varying amounts of manganese, aluminum, iron, and nickel. Manganese bronze is weldable provided the lead content is low. Gas shielded arc (gas tungsten arc or gas metal arc) welding methods are recommended. Manganese bronzes can be brazed and soldered with special fluxes.
