Braze Alloy Sizes and Yields

 

These are the four most common carbide brazing alloys:

 

Common Name

Aws #

Silver %

Melt range F

Also called

Cadmium alloy

BAg-6

50

1170 - 1270

50N or Easy-flow 3

Regular Cad Free

BAg-24

50

1260 - 1290

A50N, Safety-Silv Ni5, Ni5, 50-5

High Impact

BAg-22

49

1220 - 1305

Silverbraze 49, Ni4, TB49

56% with tin

BAg-7

56

1145 - 1205

56%, tin alloy, Safety-Silv 56, A56T

 

50% with /cadmium is the standard. As the Federal government cracked down on Cadmium use many switched to a 50% silver without Cadmium. This is about 30% weaker than the Cadmium alloy. The High Impact is a 49% alloy with Manganese instead of Cadmium and performs as well as the Cadmium alloys. 56% with tin is also popular.

 

Forms

 

Wire, ribbon and sandwich material - we can supply braze alloy in any form you wish. 

 

Yields - braze alloy is sold by size and weight.  A common question is "How long is that going to be?" here are some examples.  

1/16 (.062”) wire      62” per ounce

3/64 (.047”) wire    113” per ounce

.005" x 1" ribbon      38” per ounce

 

Wire is sold by the diameter and the weight (e.g. 5 oz. of 1/16 50% Cad free)

Ribbon is sold by thickness, width and weight (e.g. 5 oz. of 0.010” thick by 0.5” wide 50% with Cadmium)

In sandwich materials there is a layer of copper between two layers of braze alloy. This may be called trimetal or plymetal. Typically this is in a 1:2:1 ratio. Sandwich material is always a ribbon.

This alloy is made in accordance with and exceeds all specifications of:

  • The American Welding Society specification AWS 5.8
  • SAE (Society of Automotive Engineers)
  • ASTM (American Society for Testing and Materials )
  • SAE-ASTM Unified Numbering System for Metals and Alloys.
  • United States government in Federal Regulation CFR 1910.1200.
  • NIS (National Institute of Standards)

Warning Label

 

There can be hazards in  using  braze alloy.  Do not allow the fumes to be inhaled or come into contact with an operator or other person.  For complete information please request an MSDS sheet.
