Description	All materials made from non-ferrous metals. Non-ferrous: metals, including alloys, that do not contain iron in appreciable amounts. In archaeological collections, commonly copper, lead, silver, gold and zinc. Copper alloy: metal alloy principally of copper with one or more non-ferrous metals. Bronze (tin) and brass (zinc) are types of copper alloy. Galvanic (bimetallic) corrosion: electro-chemical process where one metal corrodes preferentially when in contact with another. This only applies to material excavated or discovered as part of a planned or amateur excavation or survey within the borough of Harrow regardless of boundary changes over time.
