A tuyere nozzle for a metallurgical furnace fabricated from a plurality of functional elements joined together to form a completed tuyere nozzle. The tuyere nozzle includes a nose element through which the air enters the furnace, which is formed from high conductivity, oxygen free, rolled or forged copper to resist the most severe temperature and abrasion conditions encountered in a furnace, and the pipe element, which conveys the heated air through the tuyere, is formed from lower thermal conductivity metal, as stainless steel, or ceramic lined metal, to minimize air blast heat loss, controlled water flow for uniform cooling of the hot surfaces, and preferably corrosion resistant to resist the corrosive action of molten lime and slag.
