C12000 Copper Chemical Composition (ASTM B152), Grades, Chart and Pdf

C12000 copper applications embrace the exactness of chemical composition in line with ASTM B152 standards. Often, this alloy is mainly copper-based, but with traces of other elements such as phosphorus than just copper that then help it become more conductive and resistant to corrosion. The grades of alloy in this group can be further divided into a number of specific chemical compositions and mechanical properties thus giving a comprehensive framework for selection in different applications. An illustrative chart and a descriptive pdf attachment presentation highlight the disparity in composition and features of different types of C12000 copper, which assists engineers, manufacturers and researchers to make better material selections and applications.

C12000 Copper Composition And Grades Table

The copper composition and grades table is the table of C12000 alloy’s chemical composition and classification according to the norms of ASTM. However, C12000 has a high content of copper, in excess of 99.9%, while possessing a small quantity of other elements, notably phosphorus. It is the high copper content that contributes to its conductivity and corrosion resistance. The table sorts different grades depending on their special effect and properties, thus making it easier for someone to choose materials for different purposes.

The Advantages and Disadvantages of ASTM B152 C12000 Copper Material Properties, C12000 Properties


  • Excellent Electrical Conductivity: Taking into account the performance requirements set by ASTM C12000, it delivers more than 99% conductivity which is perfect in use cases like wiring and connectors.
  • High Thermal Conductivity: It has tremendous value and the majority of the applications in HVAC systems and industrial operations use it for its high heat flow.
  • Good Corrosion Resistance: Forms a wear resistant oxide coating, but it can operate above 300°C.
  • Ductility and Formability: In manufacturing the integral of its use is that it is highly ductile and thus easier to fabricate.
  • Resistance to Hydrogen Embrittlement: The adverse effects of hydrogen break down under such high pressure, the material remains elastic.


  • High Cost: Achieving the desired degrees of purification for copper - without any traces even of oxygen- relies on an assembly line that is sophisticated and thorough, and this accounts for the added expense.
  • Limited Availability: Rare and excellent copper alloy C12000 may be unavailable in the market due to its special manufacturing process.
  • Limited Strength: C12000 may be an excellent electrical conductor, but it does not possess a sufficient strength in a structural solution and, therefore, it needs to be additionally reinforced.
  • Not Ideal for High-Temperature Applications: High temperatures and heavy duties affect the liabilities of C12000 and consequently, it is the reason why it is not suitable for these kinds of applications.
  • Susceptibility to Stress Corrosion Cracking: Using C12000 under specific loads shall lead to stress corrosion cracking so the element has to be careful in build-up.

Frequently Asked Questions

What are the differences between pipes and tubes?

Pipes are typically used to transport fluids or gases, while tubes are often used in structural applications. Pipes have standardized sizes, while tubes can have varied dimensions.

What are Butt Weld Fittings?

Butt weld fittings are pipe fittings that are welded at their ends to connect pipes together. They ensure a smooth and seamless flow of liquids or gases.

How are round bars different from square bars?

Round bars are cylindrical in shape and provide better corrosion resistance due to fewer edges. Square bars, on the other hand, are more suitable for applications requiring tighter tolerances.

What are Flanges used for?

Flanges are used to connect pipes, valves, or pumps, providing an easy way to access and maintain systems. They also help in preventing leakage and ensure a secure connection.

How do Sheets, Plates, and Coils differ?

Sheets are thin, flat pieces of metal, while plates are thicker and heavier. Coils are continuous rolls of metal used in various manufacturing processes.

What are Forged Fittings?

Forged fittings are solid metal components shaped under high-pressure conditions. They are highly durable and are often used in critical applications.

How do you choose the right Pipe & Tube material?

The choice depends on factors like the intended use, the fluid or gas being transported, temperature, and corrosion resistance required. Common materials include stainless steel, carbon steel, and alloys.

Can Flanges be used with different pipe materials?

Yes, flanges are versatile and can be used with various pipe materials, as long as the flange material is compatible with the pipe material in terms of strength and corrosion resistance./p>
