At present, photovoltaic, new energy, energy storage and other industries have entered an era of deep cost reduction and efficiency improvement. The price fluctuations of raw materials have intensified, especially the continuous rise in copper prices, making "replacing pure copper with more economical and reliable materials" the primary direction of procurement for many companies.

In this context,Small sizeCopper clad aluminum stripDue to its excellent conductivity, cost advantage and lightweight characteristics, it has gradually become a mainstream alternative material. Among many manufacturers,Raytron（Raytron) stood out and became the technical representative in the field of small-sized copper-clad aluminum strips.

Why do people choose Ruichuang's small-sized copper-clad aluminum strip?

? Mature technology, solving the pain points of traditional copper-clad aluminum

Many companies often encounter problems when actually introducing copper-clad aluminum materials: copper layer falling off, unstable conductivity, and easy breakage during processing. Ruichuang uses its independently developed "multiple rolling + vacuum annealing" technology toCompletely solve the core problems such as weak copper-aluminum bonding, poor conductivity, and dimensional drift.

? Truly achieve "small size and high precision"

There are very few manufacturers on the market that dare to mass-produce small-sized copper-clad aluminum strips with a thickness of 0.05mm. Relying on 13 high-precision rolling mill production lines and online monitoring systems, Ruichuang can provide stable batch supply. 0.050.8mm thickness, 2mm10mm width The dimensional accuracy of small-sized products is within ±0.003mm.

? Lighter, more economical and safer

• The same volume is lighter than pure copper, nearly 40%.Photovoltaic modulesLightweight design is extremely beneficial.
• The cost saving is as high as 20%-30%, and the overall cost performance is very strong.
• The conductivity is better than similar products on the market.The conductivity of the surface copper layer is above 90%, fully meeting the high current requirements of photovoltaic welding, battery connection, etc.

Typical application industries

• ? Photovoltaic module welding ribbon (main grid welding ribbon/busbar)
• ? Conductive connection materials for energy storage batteries
• ? BMS connector and FPC reinforcement tape
• ? Conductive components inside small appliances/3C products
• ? Lightweight wiring system for electric vehicles

Customers choose Ruichuang not only because of the products, but also because of the professionalism.

? National high-tech enterprise, participating in the drafting of industry standards
? With 30+ technical patents, focusing on the field of flat wire/strip deep processing
? Each batch of products undergoesConductivity, tensile strength, bonding, surface smoothnessMultiple tests
? Support small batch proofing and customized development,Fast delivery, quick response, stable service

Purchasing Suggestions & Tips

If you are a corporate purchaser looking for an alternative to copper-clad aluminum strip:

• Please pay attention to whether the manufacturer has a stable "copper-aluminum bonding process";
• Whether it can maintain good conductivity and dimensional tolerance under small specifications;
• Whether it has the ability to deliver in batches and real customer verification.

Ruichuang can do all of these.
