bronze alloyBronze is the earliest alloy in the history of metal smelting. The alloy of tin or lead added to pure copper (red copper) has special importance and historical significance. Compared with pure copper (red copper), bronze has high strength and low melting point (25% of tin smelting bronze, melting point will be reduced to 800℃.The melting point of pure copper (copper) is 1083℃.Bronze is castable, wear-resistant and chemically stable.

C31400 Leaded Commercial Bronze (CDA 314)

CDA 314, ASTM B140

Leaded Commercial Bronze C31400 combines the natural corrosion resistance of C22000 with the machinability typical of leaded brasses. Like C22000, it is an alpha brass nominally composed of 89% copper and 9% zinc, but it also contains approximately 2% lead to impart free-cutting characteristics. The relatively low zinc content of C31400 provides excellent corrosion resistance in potable water along with a pleasing golden color that matches C22000 hardware. Alloy C31400 is also suitable for outdoor use due to its resistance to stress corrosion cracking and to corrosion in general, but where the highest strength is not required.

Typical Uses for C31400 Leaded Commercial Bronze:

BUILDERS HARDWARE: Door Knobs

ELECTRICAL: Connectors for Wire and Cable, Electrical Plug Type Connectors

FASTENERS: Screws, Nuts

INDUSTRIAL: Pickling Fixtures, Pickling Racks, Pickling Crates, Screw Machine Parts
