ASTM B301 C54400 Copper Chemical Composition, Grades, Chart and Pdf

ASTM B301 C54400 is a cupro nickel alloy with excellent corrosion resistance, and high machinability, and is, therefore, suitable for maritime and industrial applications. The composition of the alloy would normally include copper (Cu) as a primary element and a small amount of zinc (Zn) and tin (Sn) to improve its characteristics. C54400 shows outstanding performances in resisting corrosion in marine environments and thus provides great chance of machinability which in its turn improves the facility of fabrication. Grades of C54400 are labeled based on differences in compositions and properties that are customized to choose between corrosion resistant, strong, and machinable types based on engineers’ needs. A comprehensive chart depicting its mechanical properties, chemical composition, and grades is provided in PDF format as a supporting material to be utilized by engineers, manufacturers and producers operating in all sectors of the economy based on copper alloys.

The Advantages and Disadvantages of ASTM B301 C54400 Copper Material Properties, C54400 Properties


  • Exceptional Electrical Conductivity: Although C54400 OFE copper is an electrical conductor, it has high capacities for electrical transfer which makes it appropriate for applications that require the effective and undistorted transfer of electricity.

  • Malleable Material: Its soft property by its intrinsic nature permits simple and easiest of forming, bending and shaping in manufacturing.

  • Impressive Thermal Conductivity: C54400 though, because of having high thermal conductivity provides the ability to be used for heat exchangers, radiators and other heat transfer process.

  • Good Corrosion Resistance: Introduction: Although it isn’t as corrosion-resistant as some alloys, C54400 offer reasonable protection from environmental chipping.

  • Susceptibility to Oxidation: The OFHC C54400's high purity makes it more easily to oxidate the metal when the metal has contact with too much humidity and oxygen, so that we need to take protective measures on it.


  • High Cost: Copper which is pure and without oxygen (Oxygen-free copper) is more expensive than normal alloys like C54400 because of its tricky manufacturing and purity conditions.

  • Limited Strength: The material has a C54400 grade, which is quite soft-making it a complicated matter when such properties as high mechanical strength ought to be realized.

  • Not Ideal for High-Stress Environments: Having low strength and oxidation hardness, as well as being brittle and quite prone to cracking, makes C54400 more suitable for restoration/decoration rather than for heavy-duty structural components.

  • Limited Work Hardening Ability: The case of C54400 copper is different since it has a very limited work hardening ability than its most commonly used electrolytic alloys; that means it does not yield to strength or toughness increase upon expensive deforming.

  • Susceptibility to Stress Corrosion Cracking: But like wrought copper C54400, the wrought copper C54400 well resists to the general corrosion; however, it is very vulnerable to the stress corrosion cracking (SCC) under some certain conditions.
