Driven by the "dual carbon" strategy, the new energy industry is developing rapidly. With the urgent demand of enterprises for cost reduction, efficiency improvement, lightweighting and material composite,Small sizeCopper clad aluminum strip<\/a><\/strong>, is gradually moving from the edge of technology to mainstream applications.<\/p>

However, it is not easy to truly achieve stable conductivity, uniform rolling, no exposed copper on the surface, and strong process compatibility.This is exactlyRaytron<\/a>\uff08Raytron<\/a>) is the core reason why it has been favored by customers for a long time.<\/strong><\/p>

1. Why more and more customers choose Ruichuang's copper-clad aluminum strip?<\/h3>

From "usable" to "easy to use", small-sized copper-clad aluminum strips that can truly allow downstream customers to import and produce with confidence are rare in the market.<\/p><\/blockquote>

Relying on the ultimate polishing of calendering technology and precise control of the copper-aluminum bonding structure, Ruichuang has created a product with high conductivity and high cost performance.existPhotovoltaic welding ribbon<\/a>, new energy connectors, FPC reinforcement tapes and other fields<\/strong>.<\/p>

2. We solved the four major pain points that customers are most concerned about:<\/h3>

\u2705 1. No delamination, no cracking - strong bonding technology<\/strong><\/h4>

The common copper layer peeling and interface oxidation problems of traditional copper-clad aluminum are effectively solved by Ruichuang through multiple rounds of high-temperature vacuum compounding + online annealing. Even if the small specifications are repeatedly bent, the copper layer still fits tightly.<\/p>

\u2705 2. Precise thickness control\u2014\u2014\u00b10.003mm dimensional tolerance<\/strong><\/h4>

The high-precision rolling mill + continuous thickness measurement system is used to ensure that the dimensional tolerance is at the forefront of the industry, the welding strip forming consistency is high, and the yield is improved 30%.<\/p>

\u2705 3. Super strong conductivity - meeting the needs of mainstream component design<\/strong><\/h4>

Aluminum core has low impedance, copper layer has high surface conductivity, and has been professionally tested for conductivity.Conductive efficiency reaches 85%-90% of copper strip<\/strong>, fully meeting the welding requirements of high-efficiency components such as PERC, TOPCon, and HJT.<\/p>

\u2705 4. Obvious cost advantage - comprehensive savings of 20%-30%<\/strong><\/h4>

In the cycle of high copper prices, the value of replacing copper strips becomes more and more prominent. Ruichuang significantly reduces material costs while ensuring performance.<\/p>
