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

    Remarques concernant le traitement et la finition de surface<\/h2>\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

      FAQ g\u00e9n\u00e9rale sur les commandes<\/h2>\n

      Quel est le d\u00e9lai de production typique pour les commandes d'aluminium sur mesure ?<\/h3>\n

      Quelle est la quantit\u00e9 minimale de commande (MOQ) ?<\/h3>\n

      La quantit\u00e9 minimale de commande est flexible et examin\u00e9e au cas par cas. Les petites s\u00e9ries et les prototypes peuvent souvent \u00eatre accept\u00e9s ; les s\u00e9ries plus importantes ou standard sont plus \u00e9conomiques. Communiquez vos dimensions et quantit\u00e9s requises pour obtenir un devis ferme.<\/p>\n

      Quels documents qualit\u00e9 accompagnent la commande ?<\/h3>\n

      6951 aluminum is a heat-treatable 6000-series alloy developed as a brazing-sheet core material for radiators and heat exchangers. Its balanced silicon and magnesium content gives good strength after brazing while resisting core erosion during vacuum or controlled-atmosphere brazing. Linsy supplies 6951 as sheet, coil, tube, bar, and wire in O, T4, and T6 tempers.<\/p>\n
