Soft Annealed Copper Clad Steel Wire - 0.20mm Ground Lead is a highly formable, low-resistance conductor designed for stable performance in grounding and bonding applications. The annealed steel core provides excellent flexibility and ease of handling, while the copper cladding ensures consistent conductivity and surface oxidation protection.
This wire is well-suited for installations requiring frequent bending, coiling, or compact routing, and is commonly used in telecommunication, electronics, and control systems where size, strength, and corrosion resistance must be balanced.
Soft annealed structure for improved formability and easy installation
Copper cladding provides corrosion protection and stable conductivity
0.20mm fine diameter suitable for compact ground path layouts
High tensile strength with maintained flexibility under repeated bending
Ideal for bonding, grounding, and low-power connection systems
Ground leads in control panels and telecom cabinets
Bonding jumpers in automotive, LED, or PCB assembly
Flexible signal return paths in EMI-sensitive systems
Compact earth wires in access control and sensor units
Internal connections in enclosures with space restrictions
Conforms to ASTM B452 or equivalent copper-clad steel specifications
Soft annealed for ease of winding and soldering
Approx. 20% IACS conductivity based on material structure
RoHS / ISO9001 / REACH certified production line
Supplied in spools, coils, or customized packaging formats
