Abstract

The tubes are filled with corrosive or non-corrosive flux supplemented or not with metal powders (Si, Zn, Ag, Cu, Cs, Cd, Al, Sn, Sb) for soft soldering (at less than 450 deg C) and strong soldering (at above 450 deg C) of aluminum with itself, with copper or with stainless steel. Granulation of flux with additives ensures the initial quality of the flux, and black residues are not left during soldering.

Description

Le flux peut être corrosif ou non corrosif, et sa température de fusion peut aller de 420 ( pour le brasage tendre) à 590 ( pour le brasage fort). Il peut être éventuellemnt additionné de poudre métallique de silicium ou/et de zinc, ou/et de cuivre, ou/et de magnésium, ou/et de nickel, ou/ et de fer, ou/et de chrome, ou/et de zirconium, ou/et de titane, ou/et de  The flow may be corrosive or non-corrosive, and its melting temperature may range from 420 (for soldering) to 590 (for brazing).

Afin-de réaliser un fil fourré destiné au brasage tendre ( température inférieure à 450 o) ou au brasage fort ( température supérieure à 450 ) de l'aluminium et de certains de ses alliages avec eux-mêmes ou avec des  In order to produce a cored wire for soldering (temperature below 450 ° C.) or brazing (temperature greater than 450 °) of aluminum and some of its alloys with themselves or with

aciers inoxydables du type 18-8 (Cr-Ni), 18-8-3 (Cr Ni Mo).  stainless steels type 18-8 (Cr-Ni), 18-8-3 (Cr Ni Mo).

L'intérêt d'un tel procédé par rapport à un fil fourré réalisé à partir de feuillard refermé par galets sur lui-même en enfermant du flux, est de per -mettre une étanchéité parfaite du tube fourré, une déformation aisée par  The advantage of such a method compared to a cored wire made from strip closed by rollers on itself by enclosing the flow, is to per -mettre perfect sealing of the cored tube, easy deformation by

tréfilage et par formage ( réalisation d'anneaux de brasage par exemple).  wire drawing and by forming (making brazing rings for example).
