Feuilles de brasure (bandes et coupes) à l'argent et au cuivre phosphore. Nos feuillards de brasage à l’argent et au cuivre phosphore présentent une surface de haute qualité avec des tolérances d'épaisseur inférieures aux exigences standard.
L'utilisation de feuillard à base d’argent pour assembler les carbures de tungstène à l'acier est très courante. Les alliages contenant du manganèse et du nickel sont très populaires, notamment en raison de leurs propriétés positives en matière de mouillage et de résistance, par exemple dans l'industrie des lames de scie. Nombre de nos clients tirent le meilleur parti de notre A 338 F, un clinquant contenant du nickel et du manganèse conformément à la norme ISO 3677. Ce feuillard présente des propriétés comparables en termes de plage de fusion, de résistance mécanique et de mouillage, avec une teneur en argent plus faible. Ce feuillard est l’alternative interessante au produit normalement utilisé A 324 F mais avec un taux d’argent réduit.
Fontargen Brazing participe à de nombreux projets de R&D dans le monde entier et travaille en partenariat avec des entreprises de l'industrie de l'outillage. Fontargen Brazing propose le soutien technique essentiel afin d’optimiser les procédés techniques en collaboration avec le client. Nous bénéficions de l’expérience necessaire que nous mettons à votre disposition pour vous conseiller dans le choix du métal d'apport idéal et pour aider les spécialistes du brasage à trouver l'application idéale.
