Silver/Copper Brazing Alloy
Brazing is a metal-joining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint, the filler metal having a lower melting point than the adjoining metal.
The filler metal flows into the gap between close-fitting parts by capillary action. The filler metal is brought slightly above its melting (liquidus) temperature while protected by a suitable atmosphere, usually a flux. It then flows over the base metal (in a process known as wetting) and is then cooled to join the work pieces together.
A major advantage of brazing is the ability to join the same or different metals with considerable strength.
This alloy is mostly used for flux-free, controlled atmosphere furnace brazing.
