In new energy,Photovoltaic welding ribbonIn the fields of battery connectors, BMS nickel sheets, etc., copper-clad aluminum materials have gradually become a popular choice to replace pure copper. Among them, the proportion of small-sized copper-clad aluminum strips is rising rapidly.
However, there are very few suppliers who can truly achieve "high precision + strong integration + fast delivery".
This is also why,More and more industry customers chooseRaytron（Raytron) as a preferred partner.
1. Why is it difficult to make small-sized copper-clad aluminum strips?
- Copper layer is easy to fall off：Conventional equipment cannot guarantee the stability of multi-layer metal composites
- Difficult to control dimensional accuracy：Small changes in width and thickness will affect the customer's downstream process
- Complex surface treatment: High conductivity, and also supports tinning, rolling, punching and other post-processing
For the vast majority of manufacturers, this is not only a technical issue, but also a systematic test of equipment, experience and technology.
2. Why do people trust Ruichuang?
Ruichuang has been focusing on the production of small-sized composite materials for more than ten years, and began its technical layout as early as the early days of the rise of copper-clad aluminum welding strips. Through continuous research and development, equipment upgrades and lean production line management, Ruichuang has achieved industry leadership in the following aspects:
? Technological breakthrough: The copper layer is firmly bonded, without delamination or breakage
Using exclusive composite rolling + annealing process, the copper-aluminum bonding rate is high, supporting long-term transmission of large current.
? Precision size control: thickness as low as 0.05mm, accuracy ±0.003mm
High-precision equipment + online detection system ensures the consistency of each batch of goods and adapts to the needs of automated welding.
? Strong customizability: flexible and changeable specifications
Support customer-specified parameter customization (thickness/width/copper layer ratio), cooperate with tinning/punching/uncoiling and other services, and have a fast delivery cycle.
? Stable production capacity and guaranteed delivery time
We have 13 high-precision rolling lines and standardized production processes to ensure fast delivery of large quantities.
3. Real feedback from buyers
"When I switched to copper-clad aluminum before, I was always worried about the conductivity and instability of the copper layer. Until I used Ruichuang's products, I found that they are not only cost-effective, but also have very good weldability and fast after-sales response."
"Ruichuang's products are particularly suitable for ourPhotovoltaic busbarThe project supports proofing, revision and fast delivery. We switched directly from trial production to mass production, and the whole process was very smooth. "
These feedbacks are not isolated cases;The common choice of dozens of customers in the fields of new energy and energy storage.
4. Material types and applicable scope (partial)
