Abstract
PURPOSE: To provide a silver-zinc oxide electric contact material excellent in practical use, provided with highly efficient deposition resistance, and insultation resistance, which material comprises more than a member of the group selected from the group consisting of Zn, In, Pb and T1 and is produced by an internal oxidation process.
CONSTITUTION: The electric contactymaterial comprises 5 to 15% by weight of Zn, 0.5 to 10% by weight of In, 0.001 to 2% by weight of at least a member of Pb and Tl, and if required, an iron group element; ≤2%, these elements being uniformly disperesed and molten in Ag. After casting and rolling, the material is heated in an oxygen atmosphere thereby to subject the same to the internal oxidation. when Pb and Tl are added to the silver-zinc system, oxides are difficult to be aggregated. The iron group element accelerates this operation, and deposition resistance and insulation resistance are improved
