1. A method of manufacturing a copper-based alloy, the method comprising:
providing in a melting furnace a feedstock in a solid phase and having a composition configured to form a molten copper-based alloy comprising at least 50 weight % copper and less than 5 weight % iron;
melting the feedstock in the melting furnace while flowing an inert gas through the feedstock to form the molten copper-based alloy under a substantially inert atmosphere; and
bubbling the inert gas into the molten copper-based alloy using a diffusive lining formed on an inner surface of the melting furnace, the diffusive lining comprising an aluminum-silicate ceramic material directly contacting the molten copper-based alloy and having a porous structure adapted for bubbling the inert gas through the molten copper-based alloy.
