Copper C11000 (Electrolytic Tough Pitch)

C110 (ETP copper) is at least 99.9% copper and is the standard choice when electrical or thermal conductivity is the priority. It is used for bus bars, electrical contacts, and heat spreaders. Request a quote or browse all materials.

Ranges span annealed to hard tempers. These are typical reference values from standard published data, not guaranteed minimums. Request material certificates in your RFQ if properties must be verified.

Advantages

Why engineers choose Copper C110

Conductivity

Excellent electrical and thermal performance.

Formability

Bends and forms readily in softer tempers.

Solderability

Solders and brazes well.

Corrosion

Good atmospheric corrosion resistance; develops a patina.

Design considerations: Soft and gummy to machine compared with brass; burrs readily; oxidizes and tarnishes; oxygen content makes C110 unsuitable for hydrogen brazing (oxygen-free C101/C102 is used instead).
