Flat, Shaped and Round Wire
Applications
Electrical/electronic applications where higher strength levels are required while maintaining good electrical conductivity.
- Heating elements
- Cable shielding
- Spring
- Electrical contact
- Semiconductor lead frames
- Spring pins
- Wave washers
Description
In general these alloys exhibit good to excellent corrosion resistance with medium to high thermal and electrical conductivity. They offer higher strength levels than pure copper alloys and some are heat treatable.
