Tianjin Ruiyuan Electric Material Co,.Ltd (Ruiyuan) was established in 2002, in the past 24years, we have been committed to "Precision Engineering for Complex Wire Solutions." This dedication has driven us to expand our product range from fine enameled copper wires to include litz wire, OCC copper wire, rectangular enameled copper wire, triple-insulated wire, and guitar pickup wire. Currently, we offer six main categories with over 20 varieties of magnet wire.

Engineering Excellence Beyond the Standard For over 24 years, Tianjin Ruiyuan (Ruiyuan) has evolved from a specialist manufacturer of ultrafine enameled copper wire into a strategic Solution Provider for the world’s most demanding industrial applications. We don’t just supply wire; we engineer the critical components that drive performance in high-frequency power electronics, aerospace, and medical technology.
Bridging the Gap in High-Frequency Innovation In an era where efficiency is non-negotiable, Ruiyuan stands at the forefront of tackling complex challenges in extreme insulation and high-frequency loss reduction. Our expertise is best demonstrated through our R&D initiatives for the European automotive sector. When global Tier 1 suppliers faced the dual challenge of solvent resistance and UL94-V0 flame retardancy for wireless charging systems, standard solutions failed. Our engineering team delivered a breakthrough: a specialized ETFE-extruded Litz wire that optimized thermal stability without compromising electrical performance—a solution now in mass production for the future of mobility.
Such case is prevalent in our company, that fully demonstrate our advantages on technology and service Besides this, these numbers tell more about us
Your Strategic Partner for Extreme Applications From 0.012mm ultra-fine enameled copepr wire to complex rectangular Litz wires, we provide the technical depth required to push the boundaries of what’s possible. Whether you are optimizing an EV drivetrain or developing next-gen power conversion, Ruiyuan is your partner in achieving unparalleled electromagnetic efficiency.
