Improvements in wires, corrosion resis

摘要

Thread corrosion resistant. A Rod of ZIRCONIUM (0.22%) Copper stretches of 0.25 mm. 0.15 mm. DIAMETER. Then is annealed in nitrogen environment to 650 V. the metal annealing (26) of Gold (28) and stretched to an outer diameter of 50 microns. The set was annealed under the same conditions as before and is a polyurethane foam insulation Layer (30).Application to sets of Magnetic Head.
