TCr4.5-2.5-0.6铬铜合金板棒化学成分力学性能物理性能
A Nickel Silicon Chromium Copper is an alloy having a high hardness and improved electrical conductivity almost equal to that of Beryllium Copper. The alloy is composed by weight of 2.0% to 3.0% Nickel, 0.4% to 0.8% Silicon, 0.1% to 0.5% Chromium, and the balance Copper.It replaces the Beryllium Copper in practically all applications.
Nickel Silicon Chromium Copper is used wherever a good electrical or thermal conductivity is required together with high mechanical properties
Applications include Electrode Holders and Seam Welding Shafts, Spot welding electrodes, Seam Welding Wheels, Projection and Butt welding dies, Plunger tips for cold chamber aluminium die casting machines, Parts of Moulds for Injection moulding of plastics, Injection-Nozzles and Cooling Pins etc.
