COPPER ALLOY DATA SHEET

 

C54400

 

Nominally composed of 87.9% copper, 4.0% zinc, 4.0% tin, 4.0% lead, and 0.10% phosphorus, Phosphor Bronze C54400 finds its primary application where strength and bearing properties are required, and, in addition, offers the corrosion resistant characteristic of the high tin phosphor bronzes.  In particular, the alloy is noted for its stress corrosion cracking resistance and its high endurance limit.  The high lead content makes it an extremely machinable alloy that is equaled by few in the wrought metal industry as a bearing alloy.

 

Hot Working:  This alloy is not recommended for hot working due to its moderate tin and high lead content.

 

Cold Working:  Phosphor Bronze C54400 has good cold workability.  When annealed, this alloy can be bent, formed, and cold worked.  The lead content prevents severe cold working operations such as deep drawing from being successfully performed.

 

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

 

Applications:  Typical applications include bushings, bearings, shafts, gears, pinions, thrust washers, valve parts and electrical connectors.

 

Applicable Specifications:  The standard specification for C54400 rod, bar and shapes is  ASTM Specification B139.  Other commercial and customer specifications may be applicable when specified.

 

Standard Forms Available:  Rod and wire.  For other forms, please consult Ansonia Copper & Brass, Inc.
