Tinned Copper-Clad Steel Wire (TCCS)
A high-performance composite conductor engineered for applications requiring both mechanical strength and electrical conductivity. Its structure consists of three layers:
Core: Low-carbon steel (C<0.10%) providing tensile strength up to 1,500 MPa.
Cladding: Oxygen-free copper layer (≥10μm thickness) enabling 30% or 40% IACS conductivity.
Coating: Uniform tin plating (2-5μm) for superior corrosion resistance and solderability.
Key Specifications
Diameter Range:Single wire: 0.10-4.00 mm
Stranded wire: 1.02-28.8 mm (7/19/37-strand configurations)
Mechanical Properties:Hard-drawn: Tensile strength ≥1,200 MPa, Elongation ≥1%
Soft-annealed: Tensile strength ≥500 MPa, Elongation ≥15%
Electrical Performance:DC Resistance (20°C): ≤0.138 Ω·mm2/m (30% IACS)
Current Capacity: 90-1,110 A (stranded wire, air ambient)
Environmental Durability:Operating Temperature: -40°C to +150°C
Salt Spray Resistance: ≥720 hrs (ASTM B117)
Advantages
* 60% lighter than solid copper with equivalent strength
* 50% cost reduction vs. pure copper solutions
* Anti-oxidation & UV-resistant tin layer
* Compliant with IEC 60468, ASTM B452, GB/T 36102
Typical Applications
Power transmission lines (coastal/industrial zones)
RF coaxial cables & CATV shielding conductors
Automotive grounding systems & EV battery interconnects
Wiring and aerospace harnesses
Customization Options
Optional PVC/XLPE insulation (up to 600V rating)
Flame-retardant (IEC 60332-1) or anti-rodent coatings
Pre-tinned ends for quick PCB soldering
