Chromium Copper Bar

Introduction

Chromium copper bar is a kind of casting alloy products combines by copper and chromium, which is through by heat treatment and cold combination methods to get the best mechanical and physical properties. Chromium copper bar through vacuum casting - hot forging - solution technique - cold forging fight - heat treatment and other production processes to obtain high electrical and thermal conductivity, high hardness, density alloys, which could provide good strength and hardness at high temperatures.

Properties

Chromium copper bar at room temperature and high temperature (400 ° С) with high strength and hardness, it is a very good electrical and thermal conductivity material. Chromium copper is also with good wear and friction-reducing, after age hardening treatment, strength, hardness, electrical conductivity and thermal resistance are significantly improved, easy welding and brazing, with good corrosion resistance in the atmosphere and fresh water high temperature oxidation resistance, can withstand the pressure of working in a very good cold and hot states, but its drawback is stronger sensitivity gap, resulting in stress concentration in gaps and sharp corners, prone to mechanical damage.

Application

Electrical industry: high-strength cables, connectors, thermal conductor, switch parts, breaker parts, switch contacts, motor and generator parts, electronics components, connectors, generators and other slot wedge.
Parts and consumable: resistance welding electrodes, resistance welding equipment parts, electrode grip, shaft and cushioning material, or as a projection welding machine large molds, jigs, spot welding electrodes, seam welding wheel, electrode holder, plastic mold parts, heat sink, plating equipment target back plate, EDM electrode tip, need high temperature conductive wear equipment parts, steel fiber plant, with production of amorphous melt pumping wheel.
