Thos Begbie only uses 99.99% pure copper cathode as its source of copper for both slab and cast coolers.

This photograph shows a typical supply of pure copper cathode from the electro-winning plant:

Thos Begbie’s copper foundry produces the world’s largest castings; typically up to 12 tons in a single casting. Four gas-fired furnaces allow for a capacity of over 300 tons of castings per month.

Four additional conduction furnaces are also available for producing special alloys of copper, heat-resistant cast iron and stainless steel. Customers often require a composite of special metals as an integral part of their final furnace components.

Copper has been used by humans for about 12,000 years! The island of Cyprus was a major source of copper for the ancient world. The word copper comes from cyprium, later cuprum, the Roman name for the Cyprian metal.

A huge deposit was discovered in 360 BC in SW Spain. The copper & iron discoloured the nearby river, called the ‘Rio Tinto’ as a result. The mining district was also named Rio Tinto.

A copper bar can be heated, rolled and drawn into wire as thin as a human hair.

Copper is corrosion resistant, non-magnetic and ant-bacterial and is widely used for electrical and communication components, as well as in heat exchangers.

Copper, when alloyed with zinc or tin, makes brass or bronze. The era around 2,000 BC to 600 BC was named the “Bronze Age”.

The first known coins minted by Julius Caesar were made of a copper-zinc alloy, while Octavianus Caesar used  Cu-Pb-Sn alloys, and the legend of the first galvanic battery using copper soldered to lead, goes back to Baghdad in 226 A.D.
