What Is 6951 Aluminum?<\/h2>\n

6951 is commonly used as the core layer of clad brazing sheet, paired with a cladding alloy such as 4343 or 4045 on one or both faces. During the brazing cycle the cladding melts and flows to seal joints, while the 6951 core keeps the assembly strong and formable. It is widely specified in automotive and HVAC heat exchangers.<\/p>\n

    6951 is normally supplied as clad brazing sheet (core plus 4343\/4045 cladding) for furnace brazing. It forms well and can be welded where cladding is absent, but the brazing cladding must be protected from contamination. Anodizing is possible but less common than for decorative 6xxx alloys.<\/p>\n

      6951 Aluminum FAQ<\/h2>\n

      Is 6951 used as bare sheet or clad?<\/h3>\n

      Almost always as the core of clad brazing sheet, with a lower-melting cladding alloy such as 4343 or 4045 on one or both faces. Specify cladding when requesting a quote.<\/p>\n

      How does 6951 differ from 3003 for heat exchangers?<\/h3>\n

      3003 is a non-heat-treatable brazing core with lower strength; 6951 is heat-treatable and stronger after brazing, suiting higher-pressure exchangers.<\/p>\n

      Which tempers are typical for brazing sheet?<\/h3>\n

      O or T4 are common as-supplied conditions because they form easily before the braze cycle; T6 cores are used where post-braze strength matters.<\/p>\n
