Laminati per brasatura

Laminati e preformati per brasatura in lega d’argento e rame fosforo. I nostri laminati per brasatura in lega d’argento e rame fosforo hanno una superficie di alta qualità con tolleranze di spessore inferiori ai requisiti standard.

L'uso della lamina d'argento per unire i carburi di tungsteno all'acciaio è molto comune. Le leghe contenenti manganese e nichel sono molto utilizzate, soprattutto per le loro proprietà di bagnatura e resistenza meccanica, ad esempio nell'industria delle lame da taglio.

Molti dei nostri clienti stanno utilizzando al meglio il nostro laminato A 338 F, un prodotto contenente nichel e manganese in conformità allo standard ISO 3677. Questo prodotto presenta proprietà comparabili in termini di intervallo di fusione, resistenza e bagnabilità, con un contenuto di argento inferiore. È un'alternativa tecnico economica al prodotto standard A 324 F.

Fontargen Brazing è coinvolta in molti progetti di ricerca e sviluppo in tutto il mondo e collabora con aziende dell'industria degli utensili. Fontargen Brazing offre il supporto tecnico necessario per sviluppare l'ottimizzazione del processo tecnico in collaborazione con il cliente. Utilizziamo le nostre conoscenze per consigliare la scelta del metallo d'apporto perfetto per la brasatura e per supportare gli specialisti della brasatura nell'applicazione ideale.

Fontargen Brazing fornisce le seguenti leghe standard in dimensioni personalizzate:
