Contact for a vacuum interrupter.

摘要

The present invention relates to a contact for a vacuum interrupter obtained by processing a contact-forming material comprising from 20% to 60% by weight of Cr, Bi in an amount of from 0.05% to 1.0% by weight of the total amount of Cu and Bi, and the balance substantially Cu into the shape of a contact, and thereafter subjecting the processed material to vacuum heat treatment. The contact for the vacuum interrupter has both excellent anti-welding characteristics and excellent voltage withstanding characteristics.
