摘要

PPROBLEM TO BE SOLVED: To obtain such characteristic as high strength and excellent formability and erosion resistance with respect to a brazing sheet to be subjected to forming before brazing. PSOLUTION: An Mn-containing Al-alloy core material is held at 560 to 630C for 8 h to apply homogenizing treatment and is clad with an Al-Si alloy brazing filler metal by hot clad rolling. The cold rolling is performed which applying process annealing if necessary, and the resultant sheet is subjected to final annealing at 300 to 500C for 3 min under the condition of (2 to 300)C/s temperature-rise rate and then to bending for reducing the elongation of the material by 3 to 20%. In the core material of the resultant brazing sheet, strength (hardness) in the vicinity of the interface with the brazing filler metal is higher by 2 to 20% than the strength (hardness) in the central part in the sheet-thickness direction in a state before forming, and the elongation of the brazing sheet is 23%.

要解决的问题：对于要在钎焊之前成形的钎焊板，获得诸如高强度，优异的可成形性和耐腐蚀性的特性。

解决方案：将含锰的铝合金芯材在560至630℃下保持8小时以进行均质处理，然后通过热包层轧制将其覆盖在Al-Si合金钎料上。进行冷轧，如果需要的话进行工艺退火，然后将所得的片材在（2至300）C / s的升温速率条件下在300至500℃下进行3分钟的最终退火，然后进行弯曲以减小材料的伸长率达到3％到20％。在所得钎焊片的芯材中，与钎料的界面附近的强度（硬度）比沿板厚方向的中央部分的强度（硬度）高2〜20％。形成前的状态，钎焊片的伸长率为23％。
