• ISO Standard Phosphor Bronze Foil  -Global Alloy Metal Supplier -From Civen 

Description 

Civen can fulfill its customer’s bronze needs from bronze sheets to bronze foil. Like brass, bronze is one of the more popular of copper alloys, making it the most commonly used alloy of this non-ferrous metals. The mixture of tin and copper results in bronze, an alloy that is less brittle than tin and iron, but harder and more durable than pure copper. The exact amount of copper in bronze is extremely variable and ranger from 60% to nearly 90% in some commercial grades. The second most prevalent element in bronze is tin, which is also variable commonly composing between 12% and 40% of the alloy.

Bronze metal is easier to melt, making it easier to make products from bonze basting. Additional elements such as manganese, lead, zinc, silver, phosphorous, arsenic can also be added to enhance specific features of special-purpose bronzes. These and other less complex varieties of bronze are available to suit a wide range of industrial applications.
