electrolytic recovery of copper from bronze

History of Copper Refrigeration and Allied Traders

Around 2500 BC, the discovery of useful properties of copper-tin alloys led to the Bronze Age. It has been documented that Israel's Timna Valley provided copper for the Pharaohs. Papyrus records from ancient Egypt reveal that copper was used to treat infections and sterilize water.

Copper is very versatile, malleable, and conductor of heat and electricity. Although copper is soft in its pure state, copper can be mixed with other alloys to create much stronger characteristics such as brass, which is copper and zinc, and bronze, which is copper and tin. It can also be alloyed with aluminum, steel, silver and nickel to

Quick Question Copper and Brass cause corrosion?

Sep 13, 2006There is no generic blend of corrosion inhibitors for all situations. Many additives use organophosphates. These work great for protecting iron and aluminum, but increase the rate of corrosion on copper and copper alloys (such as brass and bronze). Tolytriazole is excellent for protecting copper alloys, but isn't always included due to cost.
