Form

This specification covers a copper brazing filler metal in the form of a paste comprising a viscous mixture of powder in a suitable binder.

Application

This product has been used typically for joining carbon and low-alloy steels and corrosion and heat resistant steels and alloys where high strength, good ductility, and only short-time oxidation resistance above 1000 °F (538 °C) are required, but usage is not limited to such applications. Used where inserts of copper wire or sheet are impractical and where carburization of the metals being joined is undesirable.

Classification

The brazing filler metal pastes covered by this specification are classified as follows:

Type 1: The active ingredient is composed of cupric and cuprous oxides and metallic copper.

Type 2: The active ingredient is composed of metallic copper.
