Aluminum braze alloy erosion during brazing is suppressed and the brazing sheet using the same, the heat exchanger header pipes and heat exchanger

摘要

PROBLEM TO BE SOLVED: To provide an aluminum brazing alloy which has superior brazability and excellently suppresses erosion during brazing; a brazing sheet using the same; a header pipe for a heat exchanger; and the heat exchanger.;SOLUTION: This aluminum brazing alloy comprises 5.0% to 13.0% Si (by mass%, hereinafter the same), 0.05% to 1.0% Ti, 0.1% to 2.0% Mn, 0.01% to 0.5% Zr respectively, further 0.05% to 1.0% Cr as needed, and the balance Al with unavoidable impurities.;COPYRIGHT: (C)2007,JPO&INPIT
