Abstract
A quantity of continuously cast Mg brass is made by the step of melting a charge of Mg brass and then continuously casting a rod of the Mg brass through a casting die. The casting die has been previously treated by continuously casting a melt of copper or brass through it to clean out Mg deposits formed by an earlier continuous casting of Mg brass which formed the Mg deposits. The quantity of continuously cast Mg brass may be in the form of EDM wire. These methods may be used to purify scrap or used brass, by removing metal oxides to improve the material quality, thus reducing the need to use premium priced virgin copper and zinc.

Abstract
A method for making Mg brass EDM wire has the steps of melting a charge of Mg brass to form a melt of Mg brass; transferring the melt to a holding furnace; casting a rod from the melt; and drawing the rod down to a size suitable for EDM machining. Mg deposits may form in the holding furnace. These can be removed by flushing the holding furnace with molten brass.
