Abstract: An alloyed copper wire rod is formed by continuous rod-casting, wherein a core rod is driven through a crucible containing molten metal. High purity copper melt is continuously charged into the crucible; to which an alloying material is simultaneously added in a quantity which corresponds to the given casting speed of the core rod. The required alloy thus obtained is crystallized on the surface of the core-rod as it passes through the crucible and the rod produced is treated in the usual manner i.e., cooling, rolling and coiling.

Abstract: A method for galvanostatic and potentiostatic electrochemical measurement of the rate of corrosion of an object is described wherein a working electrode, counter-electrode and reference electrode are immersed in an electrolyte and the electromotive force appearing on the cell formed by the working electrode and counter-electrode is measured and related to the reference electrode and the corrosion rate of the object is derived therefrom, the object measured being utilized as a plurality of working electrodes utilized in combination with a plurality of reference electrodes. An apparatus for performing the measurements as above described is also disclosed.
