Ternary Brazing Alloys

These alloys are generally less fluid than the General Purpose Silver Brazing Alloys and their higher brazing temperatures lead to increased demands on the flux used with these alloys.

For this reason they are generally not supplied in a flux-coated form as premature flux exhaustion can result in increased post-braze cleaning costs.

These alloys have a greater strength above 200°C than the General Purpose Silver Brazing Alloys and are used where this is a design consideration.

The following table details the alloys that are silicon free and are generally preferred by UK manufacturers.
