The Advantages and Disadvantages of ASTM B111 C12200 Copper Material Properties, C12200 Properties


  • Excellent Electrical Conductivity: Copper, which is also known as C12200, with these traits, shows outstanding electrical conductivity, so this type of copper is the best choice for the use where a fast electrical transmission is a must.

  • Soft Material: This softness also allows for great shapes to be held and re-formed during various manufacturing processes, while still being sturdy enough.

  • High Thermal Conductivity: C12200 features an excellent thermal transport capacity that is well suited for use in heat exchangers and radiators or similar heat transfer applications.

  • Good Corrosion Resistance: While not at that substitutional level of corrosion resistance as some of the other copper based alloys, C12200 still give reasonable levels of protection against environmental degradation.

  • Susceptibility to Oxidation: In contrast to the other ones, C12200 with its high purity makes it more likely for oxidation to occur when exposed to air or moisture.


  • Oxygen-free copper (OFC): proves to be a more costly option compared to the usual copper alloys like C12200 because of its pure nature and the specific process of manufacturing.

  • Limited mechanical strength: Though low hardness level is associated with C12200 copper, it may be of detriment during usage where high mechanical strength are required.

  • Not ideal for high-stress environments: It is a weaker metal with alloy oxidation as the main worker and can, therefore, not be for parts of big structures.

  • Limited work hardening ability: The material of C12200 copper provides poorly with its work hardening, which implies it doesn’t become harder neither tougher significantly at all when subjected with plastic deformation (bending and hammering).

  • Susceptibility to stress corrosion cracking: Although copper C12200 high level of corrosion resistance, it is likely to be affected by corrosion in extreme condition
