BRASS BRAZING ALLOYS
Alloys with special characteristics particularly suitable for brazing brass-to-steel alloys and vice versa. Their characteristics make it possible to divide them into two large groups:
1st Group: alloys suitable for welding brass metals as well as ferrous metals, the same among themselves;
2nd Group: alloys with nickel in their composition, and particularly indicated for strong brazing of steels and brazes highly requested for great mechanical resistance.
These alloys work at a high temperature of around 890ºc and have a very wide application in sectors such as: decoration, various tools, construction, bronzes, irons, galvanized steels, the automotive industry, among others.
