Common non-ferrous alloys include bronze and brass, which have been cast since the Bronze Age. These alloys melt at lower temperatures than ferrous materials and cast well, making them ideal for decorative applications.
There are two groups of metals; ferrous and non-ferrous. Ferrous metals contain iron, for example carbon steel, stainless steel (both alloys; mixtures of metals) and wrought iron. Non-ferrous metals don't contain iron, for example aluminium, brass, copper (which can be remembered as ABC) and titanium.
