2.0492 (DIN 1709 : 1981-11) G-CuZn15Si4 2.0492 DIN 1709 : 1981-11 DIN 1709 : 1981-11 replaced by DIN EN 1982 : 1998-12 Replaced Germany CuZn16Si4-C 3.2 1)
1) Remark: G-CuZn15Si4 is a construction material with good corrosion and sea water stability and very good casting bar (however wall thickness sensitive) as well as high cavitation stability. To 200 °C the values for the heat resistance are constant. The cold strength shows to -72 °C easily rising values. The material can be chromium-plated and nickel plated well, the bearing characteristics is sufficient when moderate load and lubrication. Manufacturing properties: - casting bar: very well - cutting property: caused - soft soldering: badly - braze welding: badly - gas fusion welding: well - manual arc welding: badly - TIG welding: well - MIG welding: caused - resistance welding: caused - polishing bar (mechanical.): very well - galvanizing bar: caused - suitability for dipping tinning: badly Application: G-CuZn15Si is used for highly stressed, thin-walled, complicated construction parts for machine and shipbuilding, in the electrical industry and precision mechanics, like armatures and shaped parts, e.g. steam armatures, valves and control parts for compressed air and hydraulics with middle loads as well as for pumps and pump impellers.
