▎ 摘  要

NOVELTY - Ultra-low chromium content copper tungsten-copper chromium integral electrical contact comprises copper tungsten arc resistant end and copper chromium conductive end. The copper tungsten arc resistant end contains 50-85 wt.% tungsten and copper and inevitable impurities (balance amount). The copper chromium conductive end contains 0.05-0.2 wt.% chromium. USE - Used as ultra-low chromium content copper tungsten-copper chromium integral electrical contact. ADVANTAGE - The integral electrical contact has high electrical conductivity and hardness, and high tensile strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of the ultra-low chromium content copper tungsten-copper chromium integral electrical contact.
