Embodiments of the present invention are directed to flux-cored brazing consumables and preforms which have at least one protrusion (205) which extends from an outer surface of the consumable such that the protrusion engages with a surface of a component (100) to be brazed. The protrusion aids in securing the brazing consumable in position during manufacture, assembly and transport of an assembly to be brazed, prior to a brazing operation.
