Copper Ingots Pure Copper Ingot 99.999% Phosphorous Copper Ingots
Copper ingots are bars made of copper which have been cast into a specific shape, like rectangular, round, square, etc. Tianjin Ruiyuan provides high purity copper ingot composed of oxygen-free copper—also referred to as OFC, Cu-OF, Cu-OFE, and oxygen-free, high-conductivity copper (OFHC)—is formed by melting copper and combining it with carbon and carbonaceous gases. The electrolytic copper refining process removes most of the oxygen contained within, resulting in a compound that consists of 99.95–99.99% copper with less than or equal to 0.0005% oxygen.

Tianjin Ruiyuan Electric Material Co,.Ltd
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

- 7-10days Average delivery time.
- 90% European and North American customers. Such as PTR,ELSIT, STS
etc.
- 95% Repurchase rate
- 99.3% Satisfaction rate. Class A supplier verified by German
customer.
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.
