The Advantages and Disadvantages of ASTM B124 C10500 Copper Material Properties, c10500 Properties


  • Superior Electrical Conductivity: As far as this ASTM c10500 standard is concerned, this can be said that this standard has very high electrical conductivity on a value 99% and higher, and applying the industry experts’ view, this is the best standard for those exercises which require great current flow like for example for electrical connectors, conductors, and various components.
  • Excellent Thermal Conductivity: Being known to perform amazing thermogravimetry, this piece of material enables quicker heat transfer, which suits HVAC heat exchanger, refrigeration units, and such industrial processes where efficient thermal conductivity matters the most.
  • Robust Corrosion Resistance: It is characterized by a shiny, not scaling surface layer and a very strong oxide film, which shows good corrosion resistance in stiff temperatures. Preference to this material has grown which makes it a popular choice for plumbing systems such as pipes, plates, fittings, valves, and connectors.
  • Ductility and Formability: c10500 material possesses perfect property that enables it to be shaped into desirable models during manufacturing while being manipulated into different fabrication shapes easily.
  • Resistance to Hydrogen Embrittlement: c10500 exceeds the standard reliability even in severe environments having excess hydrogen pressure thanks to excellent stability characteristic which makes it much superior in heavy operations.


  • Elevated Cost: Oxygen-free copper is coveted for its superior purity and this comes as a result of its lack of oxygen whereas the conventional copper alloys often contain small amounts of oxygen.
  • Limited Availability: Availability of the original copper alloy formulation is quite difficult to achieve because of its surplus of such requirements which the producer has to meet. This leads to the market availability of the product becoming blurry.
  • Limited Strength: c10500 shows good electrical conductivity but due its soft nature it cannot be literally utilized as a structure as it is; therefore, it is required to come up with an additional reinforcement that can withstand the harsh conditions and still meet the desired standards.
  • Unsuitability for High-Temperature Applications: faster melting point is the real sugar problem, therefore applications is restricted.
  • Susceptibility to Stress Corrosion Cracking: C10500 steel having a specific type of stress fracture is unstable and vulnerable to corrosion cracking that require a careful consideration of the load conditions during the designing and manufacture process to ensure efficient and effective management of this risk.
