In high-demand application scenarios such as photovoltaics, new energy, and energy storage, copper-clad aluminum strips have gradually replaced traditional pure copper materials and become the mainstream welding strip solution. In the field of small-sized copper-clad aluminum strips,High technical threshold, low yield, poor product consistencyThis is a recognized problem in the industry, and there are very few companies that have the ability to supply goods in stable quantities.

This is why many customers chooseRaytron（Raytron）.

1. Technical core: precision calendering, perfect lamination

Ruichuang has more than ten high-precision rolling mills.Thickness control capability less than ±0.005mm, in the key technical points of small-size copper-clad aluminum strip, the advantages are obvious:

• Uniform copper layer thickness, avoid aluminum exposure;
• Copper and aluminum bonded tightly, to prevent delamination and bulging;
• High surface finish, can be directly used in automatic welding process;
• Support specifications from0.05mm thick × 2–8mm wideFully customizable.

2. Solve common problems of small-sized copper-clad aluminum

In the industry, small-size copper-clad aluminum strips face the following common quality challenges:

Result: Stable supply, batch consistency, customer welding qualification rate>99.5%.

3. Why choose Ruichuang? Industry recognition + technical endorsement

• National high-tech enterprise, national standard drafting unit
• have28 core patents for flat belts/composite belts
• Annual production capacity exceeds15,000 tons, focusing on copper-clad aluminum precision composite materials
• We have long-term cooperation with many leading photovoltaic companies, and our products have beenMulti-national quality certification

4. Direct cost reduction without compromising performance

Use Ruichuang small sizeCopper clad aluminum strip, not only can it achieve significant cost reduction (material cost reduction30%-50%), while not compromising on the following:

• Conductive properties：Can meet the IACS conductivity requirements above 60%;
• Welding suitability: Suitable for mainstream methods such as ultrasonic welding, hot pressing welding, infrared welding, etc.
• Corrosion resistance: Surface treatment can be tinned/anti-oxidation layer to improve long-term stability.

5. Prototype testing is welcome - mass production verification is more convincing

We sincerely invite customers to request free sample testing and provide process guidance, welding suggestions and sample evaluation support.It’s more about quality and implementation capabilities than price.
