Abstract:
1. A copper-alloy-based sliding material comprising: a Cu-based matrix containing 5 to 15 wt % of Sn; and alloy steel particles dispersed in a range of 1 to 20 wt % of the total weight into the Cu-based matrix, the alloy steel particles having a Vickers hardness in a range of Hv 225-430, the alloy steel particles containing fine carbides having a Vickers hardness greater than Hv 1000, the copper-alloy-based sliding material including the Cu-based matrix, the alloy steel particles and the fine carbides having a Vickers hardness in a range of Hv 44 to 148 as a macro hardness, the Cu-based matrix, the alloy steel particles, and the fine carbides forming a structure in which the Cu-based matrix contains the alloy steel particles each of which contains the fine carbides.
