Abstract
PURPOSE: To obtain an electrical contact material capable of forming a contact of large short circuit breaking capacity by adding a predetermined ratio of an NiCr alloy to an AgSnO2 alloy followed by sintering.
CONSTITUTION: To an AgSnO2 alloy is added 0.5W7, especially 4wt% as Cr of an NiCr alloy, and they are sintered to manufacture an electrical contact material. The NiCr alloy preferably consists of 65W95wt% Ni and the balance Cr. The amount of SnO2 contained in the AgSnO2 alloy is preferably 3W12wt% as Sn. The arc duraction of this material is short even if short circuit current is increased, and the material is about equal to an AgSnO2 electrical contact material in consumption resistance and fusion bonding resistance. In addition, it has high workability and can be hot rolled and cold rolled.
