摘要

An aluminum metal-core weld wire for producing aluminum weld deposits, the weld wire comprises a sheath and a core, the sheath being aluminum or aluminum alloy and the core containing a composition which includes metal or metal alloy powders. A method for manufacturing such an aluminum metal-core wire which comprises depositing a core composition onto a strip of aluminum, forming the strip of aluminum into a tube which contains the core composition, applying an inorganic lubricant to the surface of the tube, and drawing the tube through a plurality of reducing dies. Preferably the lubricant is molybdenum disulfide.
