Copper 102 • UNS C10200

Copper 102 is an oxygen-free copper with extremely high electrical conductivity and good formability. These characteristics make it particularly useful for electrical connectors.

Copper 102 can be deep-drawn from the annealed temper.It is corrosion resistant in normal atmosphere and water. A thin adherent oxide film forms at elevated temperatures which prevents particle contamination and enhances glass to metal seals. The Copper 102 can be readily soldered and brazed. The absence of oxygen makes welds free of inclusions.

Available Sizes:

Copper 102 is available from Hamilton Precision Metals as strip product in thicknesses from 0.0005” to 0.010” (0.0127 mm to 0.254 mm) in widths up to 12.0” (304.8 mm). The material conforms to ASTM B 152 and UNS C10200. It is also available in thickness less than 0.0005” (0.0127 mm) in widths up to 4.000” (101.6 mm) maximum.
