C11100 Copper Chemical Composition (ASTM B224), Grades, Chart and Pdf

C11100 copper, determined according to the regulations of ASTM B224, has very high electrical and thermal conductivity, and therefore, it is acceptable for a range of applications. Its chemical constituency largely consists of the element copper (Cu) with Oxygen (0) and Cadmium (Cd), which differentiates its attributes. Generally classified under ETP grade C11100, copper is highly famous for its superb purity and outstanding formability that makes it use Sheet metal manufacturing to produce diverse complicated forms with ease. Being a multi-directional one, it is used in a broad spectrum of industries, such as electrical, automotive, and telecommunications. A mechanical properties chart of tensile strength, elongation, and hardness that will help making better engineering decisions is a very important information. On the contrary, detailed information is given on a downloadable PDF document including material specifications and grades, guiding on selection of appropriate materials and inspiring designers.

C11100 Copper Composition And Grades Table

The copper composition and grades table C11100 demonstrates the characteristics and specifications of this copper version. C11100 has a high level of copper among which the amounts of arsenic, phosphorus, and silver are very small and they have the effect of making the elemental more conductive and resistant to corrosion. The array of grades of this alloy is nominated according to their individual chemical composition and mechanical properties; each giving the material a broad range of industrial uses from electrical components to architectural fittings.

The Advantages and Disadvantages of ASTM B152 C11100 Copper Material Properties, C11100 Properties


  • Excellent Electrical Conductivity: Conformance with ASTM C11100 accredit it with a conductivity more than 99% that will make it perfect for connectors and conductors such as wires and connectors.
  • High Thermal Conductivity: Considered as a treasure in HVAC systems and in industrial processes for its heating transfer efficiency.
  • Good Corrosion Resistance: The ability to form a durable oxide coating whose corrosion resistance is expected to be high above 300°C.
  • Ductility and Formability: Being the core part of important manufacturing processes and fabricated easily due to their high ductility.
  • Resistance to Hydrogen Embrittlement: Of noteworthy advantage is the high-pressure resilience it has, making the material withstand the hydrogen induced fracturing effect.


  • High Cost: Excluding oxygen from copper results in its highest purity which requires complicated manufacturing techniques and more rigorous quality testing.
  • Limited Availability: Copper alloy C11100 has a complex manufacturing chain, this could mean that it is not widely available on the market.
  • Limited Strength: Being very good in electric conductivity, C11100 lacks strength enough, which must be compensated by adding reinforcement during structural working.
  • Not Ideal for High-Temperature Applications: This feature of C11100 means it is poorly adapted for heavy-duty, high-temperature applications.
  • Susceptibility to Stress Corrosion Cracking: C11100 becomes susceptible to stress corrosion cracking under some loads. This requires considerations before using this material during manufacturing processes.

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>
