Is C110 suitable for welding and brazing?

Yes, but oxygen content can cause e mbrittlement in some processes; deoxidized copper grades may be better for welding.

How does C110 compare to C101 in conductivity?

C110 has slightly lower conductivity due to oxygen content, but is still excellent for most electrical uses.

Why is C110 the most widely used copper grade?

Because it provides an excellent balance of conductivity, formability, and cost.

Description

Copper C110 is the most widely used grade of copper, known as Electrolytic Tough Pitch (ETP) Copper. It has a minimum copper content of 99.90% and offers excellent electrical and thermal conductivity, slightly lower than C101.

Its balance of conductivity, workability, and cost makes it the standard choice for electrical and industrial uses.

Introduction to Copper C110

What

Copper C110 (UNS C11000) is an electrolytic tough pitch copper produced through electrorefining. It contains around 99.9% copper and a small amount of oxygen (~0.04%), which slightly reduces conductivity compared to C101 but improves hot workability. It is widely used in electrical wiring, bus bars, roofing, and industrial machinery due to its excellent combination of properties and availability.

Advantages

High electrical and thermal conductivity (second only to C101)

Excellent ductility and workability

Widely available and cost-effective

Suitable for hot and cold working processes

Applications

Electrical wiring and power distribution systems

Bus bars and transformers

Roofing and architectural applications

Industrial equipment and heat exchangers
