Latest Patents

Ishigami holds a patent for a brazing sheet that exhibits improved corrosion resistance after brazing. The invention pertains to an aluminum alloy brazing sheet with a thickness of 0.30 nm or less. This brazing sheet includes a core material, a sacrificial material cladding one surface of the core material, and a brazing material cladding the other surface. The core material is made of an A1—Mn—Si-based aluminum alloy containing by mass %, Cu: 0.5 to 1.3%. The sacrificial material is an aluminum alloy containing, by mass %, Zn: 4.0 to 7.0%. The brazing material consists of an aluminum alloy containing, by mass %, Si: 6.0 to 11.0% and Zn: 0.1 to 3.0%. The invention ensures that in a pitting potential after brazing heat treatment, a thickness of a region in which a potential difference from the noblest potential in the core material is 100 mV or more is 10% to 50% of the thickness of the brazing sheet.
