| Brazing Filler metal is suitable
for pure dry atmosphere brazing & is of particular advantage
when precipitation hardening & other stainless steels in
760C to 370C range. This alloy is usually used where the
precipitation-hardening heat treatment is combined with the
brazing operation. |

| Brazing alloy is a low melting
filler metal & does not contain cadmium. It is ideal for
furnace brazing. It is used by the dairy & food industry
where cadmium free joints are required. This brazing alloy is
less prone to cause stress cracking on stainless steel &
some nickel alloys. After brazing gives a closer match with
whitish metals such as stainless steel. |
