WC-BASED SUPER-HARD ALLOY POWDER, WC-BASED SUPER-HARD ALLOY MEMBER, AND METHOD FOR PRODUCING WC-BASED SUPER-HARD ALLOY MEMBER

摘要

Provided are: a WC-based super-hard alloy powder capable of producing a WC-based super-hard alloy member having high thermal conductivity and high abrasion resistance; a WC-based super-hard alloy member; and a method for producing WC-based super-hard alloy member.　This WC-based super-hard alloy powder is characterized by containing WC, Cu and at least one of Co, Fe and Cr, with the content of WC being 40 mass% or more, and the content of at least one of Co, Fe and Cr being not less than 25 mass% and less than 60 mass%, and is characterized in that the ratio a/b satisfies the relationship 0.070 ≤ a/b ≤ 1.000, where a denotes the content of Cu and b denotes the content of at least one of Co, Fe and Cr.
