Copper Casting

Copper and many Copper alloys are ideally
suited to fabrication of components by
casting.
The most flexible casting technique utilises
sand moulds. Sand moulds can be used for
production runs from simple one-off items
to long casting runs. These items can also
range in size from a few grams to many
tonnes.
The other popular casting technique uses
iron moulds and is called die casting. Die
casting is suited to long casting runs.
Both die casting and sand casting can be
used for the low cost production complex
near net-shape components. This minimises
expensive post casting machining.
Bars, sections and hollows that require tight
dimensional control are often produced by
continuous casting.
Rings, discs and other symmetrical shapes
tend to be produced using centrifugal
casting.
