The present invention relates to electrical contact materials. Silver-antimony oxide has conventionally been used as one of the electrical contact materials manufactured by internal oxidation. Silver-antimony oxide has excellent contact properties such as stable contact resistance and welding resistance, but is subject to large wear due to arcing and is inferior in voltage resistance and insulation resistance. Therefore, the inventor of the present invention has conducted extensive research to develop an electrical contact material that has contact properties that are more resistant to arc wear than this electrical contact material, and as a result has found a satisfactory electrical contact material. One of the electrical contact materials of the present invention is bismuth 0.1
~5% by weight, indium 1~10% by weight, zinc 1~
The material consists of 10% by weight, 1-10% by weight of antimony, and the balance is silver, and is internally oxidized. Another electrical contact material of the present invention is bismuth
A material consisting of 0.1 to 5% by weight, indium 1 to 10% by weight, zinc 1 to 10% by weight, antimony 1 to 10% by weight, 0.01 to 0.5% by weight of at least one of iron, nickel, cobalt, and zirconium, and the balance being silver. and is internally oxidized. In the electrical contact material of the present invention, bismuth 0.1
~5% by weight, indium 1~10% by weight, zinc 1~
The reason for setting 10% by weight of bismuth and 1 to 10% by weight of antimony is that less than 0.1% by weight of bismuth does not have the effect of suppressing granular precipitation of antimony oxide and making the structure uniform, while less than 1% by weight of indium improves welding resistance. Zinc has no effect, less than 1% by weight of zinc has no effect on improving wear resistance, less than 1% by weight of antimony does not give good results in terms of welding resistance, and more than 5% by weight of bismuth lowers the melting point of the alloy. If the indium content is too low, internal oxidation at high temperatures becomes difficult, and if the indium content exceeds 10% by weight, indium oxide will accumulate during contact opening and closing, increasing contact resistance, and if the zinc content exceeds 10% by weight, a layer of zinc oxide will precipitate and the contact resistance will increase. The resistance increases, and if antimony exceeds 10% by weight, grain boundary precipitation of oxides becomes significant and wear resistance deteriorates.
Within the range of 1 to 10% by weight of zinc and 1 to 10% by weight of antimony, an electrical contact material with sufficiently satisfactory welding resistance, wear resistance, and contact resistance properties can be obtained. Furthermore, in another electrical contact material of the present invention, bismuth 0.1-5% by weight, indium 1-10%
The reason why at least one of iron, nickel, cobalt, and zirconium is added in a total of 0.01 to 0.5% by weight in addition to 1 to 10% by weight of zinc and 1 to 10% by weight of antimony is that when dispersed in the electrical contact material. This is because the resulting uniform and fine dispersion of bismuth oxide, indium oxide, zinc oxide and antimony oxide further reduces consumption due to discharge. This is because antimony oxide and antimony oxide are not uniformly and finely dispersed, and if the amount exceeds 0.5% by weight, segregation of the antimony oxide itself increases. Next, in order to clarify the effects of the electrical contact material according to the present invention, specific examples and conventional examples will be described. After melting the materials having the compositions of Examples 1 to 10 shown in the left column of the table below and making them into atomized powder, 600
℃, 9 atmospheres for 2 days, the oxidized atomized powder was compressed and sintered, extruded and drawn, then cut and processed into headers, with a head diameter of 5 mm and a head height of 1.
A fixed contact with a leg diameter of 2.5 mm, a leg length of 2.5 mm, and a movable contact with a head diameter of 4 mm, a head height of 1.1 mm, a leg diameter of 2.8 mm, a leg length of 1.6 mm, and a spherical head shape of 5R were obtained. However, the rivet-type electrical contacts made from the electrical contact materials of Examples 1 to 10 and the same dimensions made from the materials of the conventional examples shown in the left column of the table below by the same method as Examples 1 and 2. When the rivet-type electrical contact was assembled into a hinge-type relay and an opening/closing test was conducted under the test conditions below, the results shown in the right column of the table below were obtained. Test conditions Voltage: AC100V 50Hz Current: 40A, steady 10A Load: Resistance Switching frequency: 20 times/min Number of switching: Contact force until welding occurs: 40g Breaking force: 45g

[Table] Regarding the withstand voltage, apply 1200V AC between contacts for 10 seconds, and pass if the leakage current is less than 10mA.
If it was 10mA or more, it was considered a failure. As is clear from the table above, the rivet-type electrical contacts made with the electrical contact materials of Examples 1 to 10 have higher voltage resistance and wear resistance than the rivet-type electrical contacts made with the conventional electrical contact materials. It can be seen that the welding resistance is almost equally excellent. As detailed above, the electrical contact material of the present invention has contact characteristics that are superior to conventional electrical contact materials in terms of voltage resistance and wear resistance, so it is a revolutionary product that can replace conventional electrical contact materials. It can be said that it is something like that.
