Flexible brazing alloy tape and method of making same |
摘要 |
A flexible brazing alloy tape with a binder having less than 3% by weight total organic content and no more than about 1% by weight residual ash after melting is provided by use of a polyacrylic acid polymer, glycerol and water as a vehicle in which the powdered alloy is dissolved to form a slurry prior to casting. The polyacrylic acid polymer has a relatively low viscosity defined by a molecular weight of about 450,000. The slurry is deposited on a substrate and is dried and the resulting flexible low organic self-supporting tape is removed from the substrate to be formed into desired shapes as preforms for brazing. Alternatively a brazing alloy tape comprising a binder having a similarly low total organic content is produced by mixing the powdered alloy with polyvinyl alcohol, glycerol and water and thereafter casting the tape as described above.
