If at least one of i, Zr, Bi, Ge, and Ga exceeds 3% by weight, the amount of oxides generated increases, the contact resistance becomes high, and the contact resistance becomes unstable.
また、前記合金材料にＩｎを１〜１０重量％とＳｉ。Further, the alloy material contains 1 to 10% by weight of In and Si.

) In addition to adding ~3% by weight, Fe group metals were added in an amount of ~0.01~3% by weight.
The reason for adding 0.5M amount % is to refine the crystal grains and further improve the wear resistance.If it is less than 0.01 ntli%, the effect of grain refinement will not appear, but if it exceeds 0.5 wt% However, no further effect can be obtained.

。Next, using a sliding contact material according to the present invention and a conventional sliding contact material whose compositions are not shown in the left column below, the wire diameter is 0.7 mm.
Brush wire rods were made, each cut into 8 mm lengths, and 2
Line up one end with a width of 10 mm, a length of 13 mm, and a thickness of QJm.
A brush contact was made by welding to a composite material of ++ and bending a 2R arc-shaped contact part on the other end. Then, each brush contact was brought into contact with a disk-shaped commutator, the commutator was rotated one rotation, and a sliding test was conducted under the following test conditions, and the amount of wear and contact resistance were measured, and the results are shown in the table below. The results shown in the right column were obtained.

向上しているからに他ならない。This is simply because the sliding contact material of the present invention, which constitutes the brush wire of the brush contacts of Examples 1 to 6, contains In, Si, and Zr.
This is because the addition of at least one of , +3i, Ge, and Ga increases hardness and improves wear resistance. In particular, the reason why the amount of wear of the brush contact of Example 6 is even smaller than that of the brush contacts of Examples 1 to 5 is that Fe group metal is added to the sliding contact material of the present invention that constitutes the brush wire. This is because the crystal grains are fine and dispersed, further improving wear resistance.

効果がある。As detailed above, according to the sliding contact material according to the present invention,
It has significantly better wear resistance than conventional sliding contact materials, generates extremely little wear powder, generates almost no noise, and has a lower and more stable contact resistance than conventional sliding contact materials. This has the effect that it is possible to obtain a brush contact point with
