C19140 Low Leaded Commercial Bronze Hollow Bar Rod

Ask for Price

C19140 is unique precipitation hardening alloys containing copper, lead, nickel and phosphorus. The nickel and phosphorus in the alloy combine to form nickel phosphate, which dissolves in the copper on heating to a suitable temperature, and can be retained by quenching. Subsequent aging will precipitate the nickel phosphate from solid solution in a highly dispersed manner thereby creating a remarkable hardening and strengthening effect with excellent stress relaxation properties. Subsequent cold working increases the strength still further.

C31400 Leaded Commercial Bronze Hollow Bar Rod

Ask for Price

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 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

Nickel Leaded Commercial	C31600

C31600 Leaded Commercial Bronze Hollow Bar Rod

Ask for Price

Nickel Bearing C31600 is composed of approximately 89% copper, 8% zinc, and 2% lead, but also contains 1% nickel. This alloy combines the natural corrosion resistance and machinability of C31400 with a higher tensile and yield strength resulting from the controlled addition of nickel. The relatively low zinc content provides excellent corrosion resistance in potable water along with a pleasing golden color that matches C22000 hardware. It also possesses a particular resistance to stress corrosion cracking. It is an alloy suitable for outdoor use where higher strength is required.
