Manufacturing Process
Four controlled steps to a uniform arsenical copper.
Raw material
Pure copper cathode (99.9% Cu) and clean copper scrap are selected and pre-heated to remove moisture.
Melting
Medium-frequency induction furnaces under a charcoal cover limit oxygen pick-up.
Alloying
Arsenic (0.15% to 0.50%) is added and the melt is deoxidised with phosphorus. Chemistry is checked before pouring.
Casting
Water-cooled moulds produce dense ingots and billets.
