Against the backdrop of fluctuating raw material prices and accelerating industrial transformation,"Copper replacement" has become a key word in the photovoltaic and electrical industriesAmong the many alternatives,Small size copper clad aluminum flat wireWith its outstanding performance and cost-effectiveness, it is rapidly gaining market recognition.
However, there are only a few manufacturers that can truly produce small-sized copper-clad aluminum flat wires stably and with high quality.Raytron, a leader in this field.
?? 01｜Is copper too expensive? Is aluminum not enough? Ruichuang provides a "cost-effective" solution
Pure copper is expensive, and although aluminum is cheap, it has shortcomings in conductivity. Ruichuang's small-sized copper-clad aluminum flat wire successfully combines the advantages of both:
- High purity copper on the surface → Ensures conductivity (≥85% IACS) and weldability
- Aluminum core → Greatly reduces cost and is lighter
Compared with traditional copper strips, the cost can be reduced by 20~30%, while still maintaining the same electrical performance!
?? 02｜Precise size, strong fit, suitable for automated welding lines
Small-sized copper-clad aluminum flat wire is usually used in automatic welding equipment.Thickness control, edge cleanliness, surface flatnessThe requirements are extremely high. With many years of calendering experience, Ruichuang can stably produce the following sizes:
- Thickness range:0.05mm ~ 0.2mm
- Width range:1.0mm ~ 10mm
- Width ratio>100, stable molding
- Good flatness, warpage controlled within ±0.5mm/m
The automated high-speed welding line performed well in the trial, with a customer return rate of more than 90%.
?? 03｜Strong copper-aluminum bonding, solving the pain points of copper exposure/delamination industry
Many copper-clad aluminum materials are prone to "Copper exposure, delamination, peeling" and other problems, affecting welding and conduction.
Ruichuang adopts advancedMulti-layer composite processAnd special heat treatment process to ensure the copper layer and aluminum core form a stable metallurgical bond:
- Peel strength ≥1.2N/mm
- Copper layer thickness is uniform, within ±5μm
- No blistering, no delamination, stable welding performance
?? 04｜Can be electroplated or tinned to meet various terminal needs of customers
Ruichuang small size copper clad aluminum flat wireSupport various surface treatments, more widely used:
- Can be directly tinned → Improve welding speed and reliability
- Customizable copper plating thickness
- It can be used in many scenarios such as FPC nickel strip replacement, energy storage convergence, BMS interconnection, etc.
At the same time, we support the provision of sample proofing to assist customers in conducting new project verification.
?? 05｜Stable delivery, strong batch consistency, and fast delivery!
The difficulty of small-sized products lies not only in production, but also in continuous and stable supply.
Ruichuang has 13 high-precision rolling mills with an annual production capacity of more than 15,000 tons and is equipped with a complete quality inspection system:
- Full parameter quality inspection report for each batch
- Regular specifications are in stock and customized specifications are delivered within 3-7 days
