Spec Equivalents: ASTM B140
The C31400 Leaded Commercial Bronze is the combination of natural corrosion resistance with the machining ability of leaded brass. It is the combination of 89% copper and 9% zinc and also contains 2% lead that provides free-cutting characteristics. The low zinc content provides corrosion resistance in potable water with a golden color. The alloy is suitable for outdoor use owing to its resistance towards stress corrosion cracking and where the highest strength is not required.
Applications:
- 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
