が得られるものである。In the electrical contact material of the present invention, hismuth is 0.1 to 5% by weight, cadmium is 1 to 10% by weight, and chloride is 1 to 10% by weight.
The reason why the weight lead is more than 5% by weight and less than 10% by weight is:
If bismuth is less than 0.1% by weight, it will not have the effect of promoting internal conversion or improving adhesion resistance or wear resistance, and if cadmium is less than 1% by weight, it will prevent oxide agglomeration and stabilize the contact resistance. If it is less than 1 to 10% by weight, it will not have the effect of suppressing the layered precipitation of zinc oxide and stabilize the contact resistance, and if it is less than 5% by weight, good results will not be obtained in terms of welding resistance. Moreover, if bismuth exceeds 5% by weight, consumption due to arc heat and Joule heat increases, and the melting point of the alloy drops too much, degrading withstand voltage and insulation properties.If cadmium exceeds 10% by weight, consumption due to arc heat and Joule heat increases. becomes large, deteriorating the withstand voltage and insulation properties, and when the amount of zinc exceeds 10% by weight, oxides precipitate in layers, making the contact resistance unstable. Therefore, bismuth 0.1-5% by weight, cadmium 1-10% by weight, Suzuko-IO weight%, zinc 5% by weight.
In the range of more than 10% by weight and less than 10% by weight, dark weldability,
An electrical contact material having sufficiently satisfactory wear resistance and contact resistance characteristics can be obtained.

、放電による消耗が−ｌ′８減少するからであって、０
．０１重量％未満では酸化ビスマス。At least 0.01 to 0.5% by weight of zirconium
The reason for adding this is that when it is dispersed in an electrical contact material, the resulting uniform dispersion of bismuth oxide, cadmium oxide, tin oxide, and zinc oxide reduces consumption due to discharge. This is because it decreases by 8, and 0
．． If the amount is less than 0.01% by weight, it is bismuth oxide.

ｔｌｉがｊＩ１１加するからである。Cadmium oxide, tin oxide and zinc oxide are uniformly fine 811
This is because if the amount of dispersion in 1 is more than 0.5% by weight, its own bias tli will be added by jI11.
