What is “Cu-ETP” Material?

Cu-ETP, short for Copper Electrolytic Tough Pitch, is a type of copper that is widely used in the electrical industry due to its high electrical conductivity and resistance to corrosion. 

This type of copper is commonly found in electrical wiring, power generation equipment, and other electrical applications.

One of the key advantages of Cu-ETP is its high conductivity. It has a conductivity rating of 100% IACS, making it one of the most conductive metals available. This makes it an ideal choice for applications that require the efficient transfer of electrical energy, such as power generation and transmission.

Cu-ETP is also highly resistant to corrosion, making it a durable and long-lasting choice for electrical applications. This is particularly important in coastal and industrial environments where copper is exposed to harsh conditions that can cause corrosion and damage over time.

In addition to its high conductivity and resistance to corrosion, Cu-ETP is also a versatile material that can be easily shaped and formed into a variety of different forms. This makes it well-suited for a wide range of electrical applications, including power generation, transmission, and distribution.

In conclusion, Cu-ETP is an excellent choice for electrical applications that require high conductivity and resistance to corrosion. Its versatility and long-lasting durability make it a popular choice among manufacturers and engineers in the electrical industry.

Applicable Specifications

Cu-ETP (Copper Electrolytic Tough Pitch) is a type of copper that is commonly used in the electrical industry due to its high electrical conductivity and resistance to corrosion.
The following are some of the commonly used specifications for Cu-ETP:

ASTM B187/B187M- Standard Specification for Copper Bus Bar, Rod, and Shapes and General Purpose Rod, Bar, and Shapes
ASTM B188- Standard Specification for Seamless Copper Bus Pipe and Tube
ASTM B283/B283M- Standard Specification for Copper and Copper Alloy Die Forgings (Hot Pressed)
ASTM B451 – Standard Specification for Copper Foil, Strip, and Sheet for Printed Circuits and Carrier Tapes
ASTM B506 – Standard Specification for Copper Clad Stainless Steel Sheet and Strip for Building Construction
ASTM B694 – Standard Specification for Copper, Copper Alloy, and Copper-Clad Stainless Steel Sheet and Strip for Electrical Cable Shielding
SAE J461 – Wrought and Cast Copper Alloys
SAE J463 – Wrought Copper and Copper Alloys
ASME SB124 – Copper and Copper Alloy Forging Rod, Bar and Shapes
ASME SB152 – Copper Sheet, Strip, Plate and Rolled Bar
ASME SB187 – Copper Bus Bar, Rod and Shapes and General Purpose Rod, Bar and Shapes
AMS 4500- Copper Sheet, Strip and Plate, Soft Annealed

Please note that the above is not an exhaustive list, and other specifications may also be applicable to Cu-ETP, depending on the intended application and the specific requirements of the manufacturer or end-user. Also, the standard maybe change over time so it’s important to check the latest version of the standard.

Equivalents

Copper Electrolytic Tough Pitch is a commonly used copper alloy known for its high conductivity and corrosion resistance. Other materials that can be used as a substitute for Cu-ETP include:

C10100, C10200, C10300, C10800, C12000: These are all high conductivity copper alloys with varying levels of purity and properties.

Cu-OF (Oxygen-free Copper): Cu-OF is a high-purity copper with a minimum of 99.99% copper content that has similar conductivity and corrosion resistance to Cu-ETP.

Silver: Silver is a more expensive option but has a higher conductivity than Cu-ETP.

Aluminum: Aluminum is a lower-density, lower-cost alternative to Cu-ETP that can be used in some electrical applications.

Gold: Gold is another more expensive option but has a higher conductivity than Cu-ETP.

It’s important to note that the final selection of a substitute material will depend on the specific application and the properties that are required.
