In the fields of photovoltaics, battery modules, energy storage, BMS and other high-precision fields, more and more companies are beginning to favorSmall size copper clad aluminum flat wire(CCA flat wire) as a conductive connecting material.Light weight, good conductivity, low cost, easy to shape...The advantages are obvious, but the prerequisite is that you have to choose the right supplier.
There are a lot of mixed fish and dragons on the market.Not all "copper clad aluminum" can withstand the test of mass application.
andRaytron, is a technology-based manufacturer born to solve these core pain points. We can not only produce 0.05mm~0.8mm thickness in batches and stablySmall size copper clad aluminum flat wire, and is fully ahead in terms of material types and performance stability.
Rich material types to meet diverse application needs
Ruichuang provides a variety of small-sized copper-clad aluminum flat wire material combinations, including:
?? T2 high purity copper + 1350 aluminum core：Ensure conductivity while achieving good coating stability
?? Tinned copper clad aluminum flat wire (CCA-Tin)：Improve weldability, especially suitable forPhotovoltaic welding ribbonand energy storage busbars
?? Nickel-plated CCA wire：Used in high temperature or corrosion-resistant environment, suitable for BMS and automotive-grade battery modules
?? Thick copper clad CCA flat wire：For heavy current scenarios, improve conductivity reliability
Sizes range from0.05mm*2mmarrive0.8mm*10mmSpecifications and mechanical parameters can be customized as required.
Core features are fully upgraded to meet stringent industrial needs
? 01｜High conductivity
Conductivity up to85%-90% IACS, basically meeting the electrical performance requirements of traditional pure copper strips, with low resistance and low heat generation.
? 02｜High bonding strength
Through the exclusive metallurgical hot rolling process, the copper layer and the aluminum core are tightly combined without delamination or peeling.The peeling resistance is higher than the industry average 30%.
? 03｜High dimensional accuracy
The thickness tolerance is precisely controlled within ±0.005mm, the edge is neat and burr-free, suitable forFully automatic welding line and high-speed patch processing.
? 04｜High flexibility
It has excellent bending performance, no cracking or delamination, and is particularly suitable for scenes that require repeated winding or dynamic bending.
? 05｜Strong solderability
Tinned CCA wire is stable in laser welding/ultrasonic welding/hot pressing welding, with uniform solder joints and low false soldering rate.The yield rate can reach above 99.8%.

Application customers comment on Ruichuang:
"We tried several copper-clad aluminum suppliers before, but none of them could solve the problem of poor copper layer bonding. Later, we used Ruichuang, and there was almost no peeling and rework, and we no longer had to worry about scrapping off the line."
"Ruichuang's delivery time is really fast and the quality is stable, especially the precision control of small-size lines. It is the most reassuring company I have ever cooperated with."
If you are looking for this material:
- ? Small size and high precision required
- ? Requires strong conductivity and low cost
- ? Worried about the copper layer being unstable and easy to peel off
- ? Encountering unstable supply and delayed delivery
Then don't hesitate any longer.Choose Ruichuang and let "reliability" become your purchasing bottom line!
