CuSn6 C5191 phosphorus bronze copper strip roll with nickel coating

C5191 Standard Bronze Foil Of The Alloy Of Copper And Tin Qsn6.5 - 0.1      Description:    There are many different bronze alloys, but typically modern bronze is 88% copper and 12% tin.[15] Alpha bronze consists of the alpha solid solution of tin in copper. Alpha bronze alloys of 4–5% tin are used to make coins, springs, turbines and blades. Historical "bronzes" are highly variable in composition, as most metalworkers probably used whatever scrap was on hand; the metal of the 12th-century English Gloucester Candlestick is bronze containing a mixture of copper, zinc, tin, lead, nickel, iron, antimony, arsenic with an unusually large amount of silver – between 22.5% in the base and 5.76% in the pan below the candle. The proportions of this mixture may suggest that the candlestick was made from a hoard of old coins. The Benin Bronzes are really brass, and the Romanesque Baptismal font at St Bartholomew's Church, Liège is described as both bronze and brass.   Due to bronze foil has unique performance, it has been broadly used as anti-abrasion material of electronic devices components, high air tightness casting, connectors, pins and high precision instruments. It has following features:

• high phosphorus content, great fatigue resistance;
• Good elasticity and abrasive resistance;
• No magnetic, good mechanical properties and process performance;
• Good corrosion resistance, easy to weld and braze, and no spark upon impact;
• Good conductivity, safe in high temperature.
