Composite PV ribbon as the hero product
The homepage and product architecture now lead with copper-aluminum composite PV ribbon, busbar ribbon, interconnect ribbon and round solar ribbon instead of generic copper strip or foil.
What Makes Raytron Different
Not a generic metal-material site: a composite PV ribbon and clad conductor platform
Raytron’s differentiation is the combination of copper-saving PV ribbon, clad conductor engineering and a clear 2030 product architecture.
Organized by material system plus form
CCA, CCS, NCC and SCC are separated by round wire, flat wire, strip, narrow foil, foil and stranded forms so buyers and AI engines can identify the exact offer.
Clear current, strategic and roadmap status
SCC is marked as a 2030 strategic high-end family, while enameled bimetal conductors are framed as a 2028 roadmap direction after planned equipment investment.
2030 Product Roadmap
Current production, strategic expansion and 2028 roadmap in one view
Procurement visitors can immediately distinguish current focus products, 2030 strategic products and 2028 roadmap/preheat directions.
Now Current hero business Copper-aluminum composite PV ribbon, busbar ribbon, interconnect ribbon and round solar ribbon. 2030 Clad conductor platform CCA, CCS, NCC and strategic SCC products across wire, flat wire, strip, foil and stranded forms. 2028 Enameled bimetal preview Planned enameling equipment investment for bimetal round wire and precision flat enameled wire.

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 over 80% IACS conductivity. 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 at the atomic level with bond strength ≥60 MPa, while electroplating merely deposits a thin surface layer. Our process ensures no peeling, no delamination, and superior thermal stability — 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), ISO 14001 (Environmental 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 Aerospace & Defense. We have 3,000+ customers in over 50 countries.
What is the lead time for samples and bulk orders?
Sample lead time is typically 3–7 business days. Mass production orders are delivered within 7–14 business days depending on product specifications and order volume. We offer 24,000 tons/year production capacity with flexible scheduling to meet urgent demands.
Can RAYTRON provide custom specifications?
Yes. Our R&D team supports full customization including custom copper cladding ratios (10%–90%), diameters from 0.05mm to 12mm, flat wire dimensions, and special alloy combinations. We provide free samples and dedicated application engineering support for new projects.
