With the rapid development of photovoltaic and energy storage industries, enterprises are facing more and more challenges in material selection: stable conductivity, cost control, and long-term reliability are required. Especially in the field of small-sized copper-clad aluminum flat wires, incorrect selection will not only affect product performance, but may also cause rework and loss.
At this time, it is particularly important to choose a manufacturer with mature technology and stable delivery.Raytron, is such a trustworthy partner.
Why are companies increasingly trusting Ruichuang's small-sized copper-clad aluminum flat wire?
1? Mature technology, strong bonding without delamination
Traditional copper-clad aluminum products often have the problem of copper layer falling off and loose bonding.Plasma pretreatment + vacuum annealing + high pressure rollingTechnology, the multi-layer composite copper layer is firmly combined with the aluminum substrate,Even secondary processing is not easy to peel off.
2? Ultra-high dimensional accuracy, stable even in small sizes
Mass production possibleThickness starts from 0.05mm, width starts from 2mmUltra-small specification products, equipped with online monitoring and constant tension control system, size deviation ≤ ± 0.003mm,Meet the stringent requirements of automatic soldering and high-speed placement equipment.
3? Excellent electrical performance, not afraid of challenges
The surface copper layer is made of high-purity electrolytic copper, with a conductivity of ≥90%IACS. After multiple batches of customer tests, its conductivity efficiencyNearly pure copper, fully competentPhotovoltaic welding ribbon, connecting pieces and other high-frequency power-on conditions.
4? Strong batch consistency, reducing customer risks
Ruichuang is equipped with an MES traceability system, which can control the entire process from raw material entry, rolling and lamination, inspection and packaging.Ensure that each batch of goods is stable and consistent, effectively helping customers reduce the risks brought by material fluctuations.
5? Fast delivery and good service
It has 13 high-precision rolling lines with a monthly production capacity of over 100 tons. It has sufficient inventory of conventional models and supports1-3 days for proofing, 7 days for fast delivery,The technical team will follow up and provide guidance throughout the process to ensure that customers have a worry-free import.
