Core Product Pathways
Start with PV Ribbon / CCA / CCS / NCC
Composite PV Ribbon
For solar module interconnection, busbar collection and copper-saving module designs.
Key benefit: reduce copper usage while keeping solderable surfaces and a module qualification path.
CCA Conductors
For lightweight cable, high-frequency conductors, flat wire and foil evaluation.
Key benefit: balance conductivity, weight and cost with copper clad aluminum construction.
CCS Conductors
For grounding, coaxial cores, aerial conductors and strength-sensitive connections.
Key benefit: combine steel-core strength with copper-layer conductivity and corrosion resistance.
NCC Conductors
For battery connection, weldable surfaces, corrosion-resistant strip and foil evaluation.
Key benefit: nickel surface supports weldability, corrosion resistance and connection reliability validation.

Frequently Asked Questions
Expert answers about bimetallic materials, manufacturing, and applications
What is bimetallic composite wire and why is it better than pure copper?
Bimetallic composite wire (e.g. Copper Clad Aluminum, CCA) is manufactured using our proprietary Clad & Weld technology, creating a true metallurgical bond between two metals. Compared to pure copper, CCA offers 30–40% weight reduction, up to 40% cost savings, while maintaining 62–70% IACS conductivity depending on copper ratio. It is widely used in EV motors, PV ribbon, battery tabs, and cables.
What is the difference between Clad & Weld and electroplating?
Clad & Weld creates a permanent metallurgical bond with bond strength ≥60 MPa, while electroplating merely deposits a thin surface layer. Our process is designed to resist peeling and delamination after validated bending and thermal cycling tests — making it suitable for demanding EV, aerospace, and energy storage applications.
What quality certifications does RAYTRON hold?
RAYTRON is certified to ISO 9001:2015 (Quality Management) and complies with RoHS and REACH regulations. We also meet ASTM international material standards and China National Standards (GB/T). Every batch is 100% electrically and mechanically tested.
What industries use RAYTRON bimetallic materials?
Our materials serve diverse industries: Electric Vehicles (motor windings, busbars), Photovoltaic Solar (PV ribbon, tabbing wire), Battery Energy Storage (battery tabs, connectors), Cable & Conductor, Electronics & Semiconductors, and Industrial Motors. 15,000 tons/year capacity, 13 precision rolling lines.
