CO-BASE ALLOY HAVING EXCELLENT EROSION RESISTANCE TO MOLTEN LEAD-FREE SOLDER AND LEAD-FREE SOLDERING EQUIPMENT MEMBER COMPOSED OF THE CO-BASE ALLOY

摘要

PROBLEM TO BE SOLVED: To provide a Co-base alloy having excellent erosion resistance to lead-free solder, more particularly to Sn-Ag-based lead-free solder and a lead-free soldering equipment member composed of the Co-base alloy.;SOLUTION: The Co-base alloy has a composition containing 20.0% to 35.0% Cr, 3.0 to 15.0% W, 0.1 to 25.0% Fe, 0.01 to 1.20% C, 0.5 to 2.0% Mn, 0.1 to 2.0% Si, further containing one or two kinds among (a) 1.0 to 24.0% Ni and (b) one or two or more kinds of 0.01 to 0.15% La and 0.01 to 0.15% Ce, (c) 0.001 to 0.05% Mg or two or more kinds among (a) to (c) and consisting of the balance inevitable impurities. The lead-free soldering equipment member is composed of the Co-base alloy.;COPYRIGHT: (C)2006,JPO&NCIPI
