CHROMIUM-ZIRCONIUM BASE COPPER ALLOY FOR CONTINUOUS CASTING MOLD

摘要

PROBLEM TO BE SOLVED: To provide a chromium-zirconium base copper alloy for continuous casting mold and the continuous casting mold composed of this copper alloy. SOLUTION: The continuous casting mold has the composition of 0.1-1.5 mass% Cr, 0.01-0.25 mass% Zr, 0.01-0.3 mass% Si and the balance Cu with inevitable impurities, and the structure uniformly dispersing the compound of Cr and Si in the matrix.
