Quality of a Copper-Phosphorus Alloy

Experimental melting was carried out in a Tamman furnace to obtain a ligature (10, 06 % P ; 73, 14 % Cu ; 15 % Fe ; the residue is represented by impurities). The alloy was subjected to the electron microscopic study using an X-ray microanalyzer, thus revealing the alloy structure represented by copper phosphide Cu3P(1+x), iron phosphide Fe2P, solid solution of Si and P in copper, and eutectic. Copper-phosphorus alloy, smelted using crude phosphorite, can be recommended for complex alloying of cast irons and steels for various functional purposes. When using phosphorite concentrates that have been enriched according to the developed magnetic fl otation scheme, the iron content in the alloy is minimal.
