C31400 LEADED COMMERCIAL BRONZE
C31400 LEADED COMMERCIAL BRONZE
Product Code : C31400
Product Description

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
