Influence of Mischmetal on Performance of Copper Based Electric Contact Materials


Article Preview

This paper suggested that the addition of a proper amount of mischmetal efficiently improved the contact face and its mechanism of contact materials, enhancing their electrical conductivity. At the same time, their inoxidizability and non-fusibility were also highly improved, while the temperature elevation of the contactor during operation was dramatically reduced.
