The Advantages and Disadvantages of ASTM B42 C52100 Copper Material Properties, C52100 Properties

    Advantages:

  • Excellent Electrical Conductivity: Among other benefits, C52100 boasts of excellent electrical conductivity which is really important for applications requiring high value of current flow like connectors and conductors.

  • Hydrogen Embrittlement Resistance: C52100 is a hydrogen embrittlement resistant alloy that considers the issue of durability in its use for a long time, which is a problem facing most applications.

  • Corrosion Resistance: The brazing alloy has unique oxide non-scaling characteristics which is why it performs well in applications like forming glass-to-metal seals. Those work in high corrosion environments.

  • Formability: Its high formability enables it to be formed deep in a press and therefore is useful where great detail needs to be achieved in the finished part.

  • Low Magnetic Susceptibility: UNS C52100 being non-magnetic has a very low magnetic permeability which is great for applications where magnetic interference is a crucial issue.

    Disadvantages:

  • Limited Strength: Although C52100 has high-notch electrical capabilities, it does not have these properties at all in terms of mechanical strength and because that is why it needs other reinforcements to be an option in structural applications.

  • Cost: C52100 Oxygen-free Copper commands a higher price than passenger automotive copper alloys because it involves special production techniques which strive for maximum purity level.

  • Susceptibility to Stress Corrosion Cracking: C52100 has a high susceptibility to stress corrosion cracking which is a cracking of the component caused by the interaction between water and stress. Designers must pay a lot of attention to this phenomenon during the design process.

  • Limited Wear Resistance: The major drawback of this type, which is no doubt its softness in nature, is the fact that it is easily worn out, including in high-friction conditions.

  • Not Ideal for High-Temperature Applications: C52100's property of low melting value takes this metal out of formula in applications having elevated temperatures.
