Copper-chromium contacts are key components in vacuum switch appliances such as vacuum circuit breakers, contactors, load switches, etc. They undertake the task of connecting and disconnecting arc circuits and load circuit currents, and require high voltage carrying capacity in a vacuum environment. , High breaking capacity and low cut-off value, welding tendency and other properties.
A new generation of copper-chromium contact materials refers to advanced electrical contacts fabricated via powder metallurgy. These composites utilize a matrix of copper (Cu) reinforced with dispersed chromium (Cr) particles to optimize conductivity and arc resistance. While no single molecular formula applies to these alloys, the primary phases are defined by CAS numbers for Copper (CAS 7440-50-8) and Chromium (CAS 7440-47-3).
Store in dry environments to prevent oxidation. Avoid inhalation of fine dust during machining; wear appropriate respiratory protection. Do not use as pharmaceutical agents or for direct biological contact.
