As copper-clad aluminum welding strips gradually replace pure copper welding strips, more and more photovoltaic companies are aware of a key issue:
Not everyone can make small-sized copper-clad aluminum flat wire stable and reliable.

Many manufacturers often encounter the following problems after purchasing:

• Uneven copper layer thickness leads to fluctuations in conductivity
• Too large dimensional tolerance ? Increased welding defect rate
• Unstable delivery time ? affects the production schedule of the entire line
• Copper and aluminum peeling ? Risk of failure in engineering applications

andRaytron, is a professional manufacturer that solves this series of "pain points".

? Stable batch supply to ensure production rhythm

Ruichuang has a number of mature precision continuous rolling lines and automatic control systems, which can realize the production of small-sized (such as 0.05~0.30mm thickness) copper-clad aluminum flat wires.Mass and stable production.
Whether you are conducting trial production verification or monthly bulk purchases, Ruichuang can provide highly consistent products, deliver on time, and avoid production delays.

? Strictly control the process, higher yield

We focus on several core technical difficulties of small-sized copper-clad aluminum flat wires, such as:

• Copper-aluminum bonding strength
• Copper layer thickness control
• Surface uniformity and tin plating suitability

All formulatedFine process parameter control standards, ensuring small differences between batches and stable welding performance, helping customers improve the yield of automated production.

? Copper clad aluminum does not reduce performance, but has more advantages

Some people still have doubts about copper-clad aluminum, believing that it has poor conductivity and is easy to break.
However, with the support of Ruichuang's small-scale composite technology, the performance of copper-clad aluminum materials has been achieved:

• Electrical conductivity is above 80% IACS, meet the mainstreamPhotovoltaic welding ribbonCurrent requirement
• The tensile strength is higher than that of pure aluminum substrate 20%, more resistant to pulling and welding
• Excellent corrosion and oxidation resistance, supporting long-term use of outdoor components

?? Widely used and mature cases

Ruichuang's customers are:

• Photovoltaic modulesManufacturer
• Battery Cell Processing Plant
• Energy storage connection system supplier
• New energy vehicle electrical connection solution provider

They choose Ruichuang not only because of the quality of our products, but also because of ourHigh degree of cooperation and response speed in customer project cycle.
