COPPER ALLOY DATA SHEET

 

C35300

 

High Leaded Brass, so named because of its high lead content, is a brass with a slightly lower copper content than the C34000 series brasses, but of a copper content similar to free cutting brass C36000.  With approximately 61.5% copper, 36.5% zinc, and 2% lead, this brass fulfills the need for a strong, hard brass with good machinability.

 

Unlike the C34000 series brasses, the composition of C35300 falls within the alpha + beta range.  The beta grains give it increased hardness and rigidity, but a more limited ductility.  However, the ductility of C35300 is not as limited as that of C36000.

 

Hot Working:  C35300 has poor hot workability due to its lead content.

 

Cold Working:  C35300 has fair cold workability.  Although its formability is limited, it can be finished in the annealed state, which gives a moderate amount of formability combined with excellent machinability when so desired; however, C35300 is usually furnished in a hard temper for purposes that do not require much forming and where machinability is important.  Common fabrication processes include bending, flaring, roll threading and heading.

 

Joining:  Joining by soldering is excellent, while good by brazing.  The lead content prevents successful welding.

 

Applications:  Applications of C35300 include clock and watch parts, and hardware such as gears, nuts, rivets and screws.  Other applications include bicycle spoke nipples, drawer handles, drawer pulls, faucet seats and stems.

 

Applicable Specifications:  When so specified, C35300 will be manufactured to the latest revision of Specification ASTM B453 for rod and wire.

 

Standard Forms Available:  Rod, bar and wire.
