High temperature wear-resistant aluminum-bronze-based material

Abstract

Provided is a material endowed with high wear resistance in high-temperature environments. This high temperature wear-resistant aluminum-bronze-based material has an Al content of 9.0 mass % to 11.0 mass %, inclusive, an Ni content of 1.0 mass % to 3.0 mass %, inclusive, an Mn content of 8.5 mass % to 15.0 mass %, inclusive, an Si content of 2.0 mass % to 4.0 mass %, inclusive, an Fe content of 0.5 mass % to 5.0 mass %, inclusive, and a Co content of 0.01 mass % to 1.5 mass %, inclusive, with the remainder being substantially Cu.

1 . A high temperature wear-resistant aluminum-bronze-based material, wherein
 an Al content is 9.0% by mass or more and 11.0% by mass or less,   an Ni content is 1.0% by mass or more and 3.0% by mass or less,   an Mn content is 8.5% by mass or more and 15.0% by mass or less,   an Si content is 2.0% by mass or more and 4.0% by mass or less,   an Fe content is 0.5% by mass or more and 5.0% by mass or less, and   a Co content is 0.01% by mass or more and 1.5% by mass or less, with the remainder being substantially Cu.   
     
     
         2 . The high temperature wear-resistant aluminum-bronze-based material according to  claim 1 , wherein the high temperature wear-resistant aluminum-bronze-based material has a structure in which an Fe—Mn—Si-based hard material is dispersed. 
     
     
         3 . The high temperature wear-resistant aluminum-bronze-based material according to  claim 1 , wherein the high temperature wear-resistant aluminum-bronze-based material has a Vickers hardness of HV280 or more, an elongation of 0.5% or more, and a tensile strength of 500 N/mm 2  or more. 
     
     
         4 . A sliding member having a base material of the high temperature wear-resistant aluminum-bronze-based material according to  claim 1 .
