existPhotovoltaic welding ribbonIn terms of material selection, many companies face a common problem:Copper prices are rising, the cost of pure copper materials is high, small-sized products are hard to find, delivery times are unstable, and quality is difficult to guarantee.
andRaytron, is a powerful manufacturer that stands out in this "material bottleneck" stage.
AsNational High-Tech Enterprise, Ruichuang focuses onHigh precision flat wireMaterial manufacturing for more than ten years, especially inSmall size copper clad aluminum flat wireIn the field, it has profound technical accumulation and industry reputation.
? Why are more and more customers choosing Ruichuang's small-size copper-clad aluminum flat wire?
1?? Rich specifications to meet different battery process requirements
from 0.05×2mm to 0.8×10mmRuichuang supports the customized production of dozens of standard and non-standard small-sized copper-clad aluminum strips to meet the needs of different technical routes such as MBB, HJT, TOPCon, and flexible components.Optional copper layer thickness, tinning scheme, coating treatment, packaging method, everything is available to accurately match customer process requirements.
2?? High quality materials with excellent conductivity
Ruichuang uses high-purity aluminum substrate + high-quality electrolytic copper layer composite, combined withSelf-developed calendering combined process and heat treatment process, high conductivity and low contact resistance, far exceeding ordinary CCA flat wire, can effectively improvePhotovoltaic modulesoutput power and stability.
3?? Tight bonding, no delamination, no "aluminum exposure"
One of the core problems of conventional small-sized copper-clad aluminum strips isThe copper layer is not firmly bonded, too thin, and easy to delaminateRuichuang adopts the solution of hot compound + multi-pass rolling + thick copper control.The copper layer is evenly attached, without bubble interlayer and has high peeling strength, greatly reducing the risks of "copper skin falling off" and "welding failure" during welding.
4?? Good processability, suitable for mainstream solder strip production lines
In actual processing, Ruichuang's copper-clad aluminum flat wireGood ductility, moderate tensile strength, stable bending performanceWhether it is cutting, stretching or tinning, it shows good consistency and equipment compatibility, avoiding customers' secondary rework.
5?? Significant cost advantage, helping enterprises reduce costs and increase efficiency
While ensuring the performance, Ruichuang's copper clad aluminum stripThe cost control per unit length is significantly better than that of pure copper strip, suitable for large-volume component factories and foreign trade orders, helping customers improve their overall competitiveness.
