contactUNS C28000 brass alloys are annealed between 427 and 593°C (800 and 1100°F). Cold Working. UNS C28000 brass alloys have fair cold working capacity. Welding. Welding processes recommended for UNS C28000 brass alloys include brazing, soldering, butt welding, oxyacetylene welding, spot welding and gas shielded arc welding.
contactcontacts should be bifurcated to help insure circuit continuity on contact closure. Tungsten Tungsten contacts are for use in high voltage applications, usually where highly repetitive switching is required. Tungsten has a melting temperature of 3,380oC which gives it excellent arc-erosion resistance.
