Percon^® 17 Conductor Wire

back to top

Conductor Wire

Percon 17 was developed to replace cadmium copper C162, specifically soft temper cadmium copper. This alloy is also available in hard temper.

Key Attributes of Percon 17

Is not engineered for Conductors specifying ASTM B624. [See Percon 24 and Percon 28].
Does not contain any cadmium or environmentally hazardous elements.
Has excellent resistance to corrosive environments.

Percon 17 is available bare or plated with silver, nickel or tin.
