Problems of manufacturing wires for the ITER magnetic system are considered. Results for Nb{sub 3}Sn wires 0.80--0.85mm in die manufactured using bronze technology under commercial conditions are given. Wires containing up to 45,000 filaments with volume fractions of copper stabilizer up to 56%, chromium coatings 2 mm thick and having critical current densities (non Cu) up to 650 A/mm{sup 2} (12T, 4.2K) are discussed. Wires with extended tin sources and volume fractions of copper stabilizer equal to 60% are investigated. Jc (non Cu) for such wires 0.85 mm in die reaches 1,000 A/mm{sup 2} (12T, 4.2K) with hysteresis losses < 550 mJ/cm{sup 3}.
