It is well known that various types of Fe-based sintered alloys are predominantly used as the scraping plate material for the current collector of the electric car.

ある。On the other hand, in recent years, electric vehicles have tended to become faster and faster, and now commercial operation at an hourly speed of 270 km has become a reality, and even commercial operation at an ultra-high speed of 300 kmh or more has become possible. Although planned, it is the current situation that the above-mentioned conventional Fe-based sintered alloy siding plate material for current collectors, when used for ultra-high speed running, has a significantly rapid wear progression.

のである。Therefore, the present inventors have
From the above viewpoints, as a result of research to develop a current collector siding plate material that exhibits excellent wear resistance even in an ultra-high-speed running of an electric vehicle, as a result, (Hereinafter,% means% by weight), Ni: 1 to 20%,
If the W-based sintered alloy containing Fe: 0.5 to 10% and the balance of W and inevitable impurities is used, the resultant W-based sintered alloy siding plate material constitutes this. W, which is the main component of the W-based sintered alloy, ensures excellent heat resistance, oxidation resistance, arc resistance, and self-lubricating property, and Ni and Fe that form a binder phase ensure strength and toughness. Therefore, we have obtained research results that show excellent wear resistance not only in ordinary high speed running but also in ultra high speed running of 250 km / h or more.

うになるという理由にもとづくものである。In the slab material for a current collector of the present invention, the contents of Ni and Fe of the W-based sintered alloy constituting the siding material are Ni: 1 to 20% and Fe: 0.5, respectively.
The reason for limiting the content to 10% is that if the Ni content is less than 1%, the desired strength cannot be secured, while if the Fe content is less than 0.5%, the desired toughness can be secured. On the other hand, if the Ni content exceeds 20% or the Fe content exceeds 10%, the W content becomes relatively low, and the above properties brought about by W are impaired. It is based on the reason.
