About Copper, Brass, and Bronze

Temper Rating: Softened (Annealed)
Heat Treatable: No
Tensile Strength: 29,000 psi
Specifications Met: ASTM B3

This wire is polished to a mirror-like finish. Offering high electrical conductivity and formability, 110 copper is 99.9% pure. Also known as ETP copper, it's often used as grounding wire. It has a soft temper and will stay in place when bent.

Tin-Coated Multipurpose 110 Copper Wire

Temper Rating: Softened (Annealed)
Heat Treatable: No
Tensile Strength: 29,000 psi
Specifications Met: ASTM B3

The tin coating provides a higher level of corrosion resistance and makes it easier to solder than Mirror-Like Multipurpose 110 Copper Wire. Offering high electrical conductivity and formability, 110 copper is 99.9% pure. Also known as ETP copper, it's often used as grounding wire. This wire has a soft temper and will stay in place when bent.

Super-Conductive 102 Copper Balls

Yield Strength: Not Rated
Hardness: Not Rated
Temper: H04 (Full Hard)
Heat Treatable: No
Specifications Met: ASTM B2, ASTM B3

With 99.99% copper content, 102 copper has higher purity than 110 copper, resulting in superior electrical conductivity. It's commonly called OFE and OFHC copper. Use it in electrical applications, such as for coaxial cables and terminal lug.
