THE PRECIPITATIVE HARDENING ALLOY COPPERS, THEREOF ITS MANUFACTURE METHOD

摘要

Until now, chromium alloys used in arc welding, resistance welding electrode materials, and welding device parts are made of chromium alloy copper or zirconium alloy copper products, so that chromium remains insoluble at high melting temperatures. And the loss of chromium due to the inflow of oxygen and the problem of causing content imbalance and the formation of a strong oxide film on the surface of the product due to the high temperature treatment in the subsequent processing, which requires surface scalping to remove it. Due to the limiting plasticity, the energy consumption due to high temperature heat treatment is also high when processing into the required product shape.;The present invention omits the high temperature heat treatment process with a new compounding ratio, shortens the process, prevents loss due to scaling, balance alloys, excellent ductility, easy processing, and mechanical and physical properties. I found a ratio, and even though the conductivity fell slightly, I applied a high strength pledge value, so I invented a product that can solve the consumer's difficulties.;Melting, limit firing deoxidation, precipitation hardening, scalping, bubble-in jig, granules, flake type Flake Type) Alloy, Go-Stop Pattern,
