Chemical Composition
The material of choice for the new C110 line is pure copper, which has a 99.9% copper content with the other 0.1% being oxygen.
C110 is a highly conductive copper-based alloy with outstanding electrical and thermal conductivity properties, which is superior to other products available on the market. When heated, it is not brittle or embrittlement-prone like other copper alloys, such as copper alloy 122. C110 also contains the same amount of oxygen that occurs naturally in pure copper (Cu). This makes the alloy ductile, which is beneficial for electronic components that must be free from hazardous impurities and oxide films.
C110 has excellent electrical conductivity, outstanding thermal conductivity, freedom from hydrogen embrittlement, and the potential for cold-working.

Other Common Names for C110 Copper Alloy
Electrolytic Tough Pitch (ETP) copper is another name for copper alloys with a high carbon content, such as C110. They are also more technically referred to as UNS C11000, CDA 110 ETP, C110, and ISO Cu-ETP.
Applications of C110 Copper Alloy
C110 is commonly used in industrial applications where there is a need for ductility (such as in plumbing or roofing) or electrical conductivity (for example, electromagnets, bus bars, electrical motors, and other electrical equipment). It's most often utilized in the home/residential/ architectural realm for its color (such as a kitchen backsplash or cutting board) or heat transfer qualities (e.g., pots and pans).
In the building and construction industry, C110 Copper has many applications. These typically include: plumbing hardware, wiring, skylight frames, flashing, gutters, and more.
Copper 110 can be welded with precaution, but generally the sort of inert gases required are not recommended for use with copper.
