Aluminium Brazing Rings
Aluminium Brazing Ring is a welding ring that container magnesium aluminum filler metal. The weld deposit of this filler metal offers good corrosion resistance when exposed to salt water. This alloy is commonly used on base metals 5050,5052,5083,5356,5454 and 5456. The post-anodizing color tint of the weld area is white.

Have good fillet forming properties with ability to bridge wide gaps. Their wide melting range limits their applications. Due to their wide melting range they are somewhat more subject to liquation and may require more care during brazing. Therefore, they are not normally recommended for applications with slow heating rates.

A free flowing general purpose brazing alloy. It’s broader melting range is helpful where clearances are wide or are not uniform. Unless heating is rapid, care must be taken that the lower melting constituents do not separate out by liquation.
