Today, photovoltaics, new energy, energy storage and other industries have increasingly stringent requirements for conductive materials.cost,weight,SustainabilityThe shortcomings in other aspects are gradually emerging.RaytronSmall size copper clad aluminum flat wire, with its superior material properties and stable processing technology, is gradually becoming the new favorite of the industry.
? Material structure: copper and aluminum integrated, tightly combined
Ruichuang adoptsHigh-precision composite process, to achieve the copper layer and aluminum coreMetallurgical bonding, not simply coated or coated, to prevent delamination, blistering, and voids. The copper layer thickness is uniform and continuous, ensuring stable welding and conductive properties.
? Excellent conductivity, meeting high efficiency output
Although aluminum is used as the core, the outer layer is pure copper, so that the overall conductivity of the product can reach **≥85% IACS**, which fully meetsPhotovoltaic modules, battery cells, etc. have strict requirements on conductive efficiency.
- Pure copper outer layer enables fast and efficient welding
- Efficient conduction to ensure that energy output is not affected
? Lightweight and high strength, helping the system reduce weight
Compared with traditional pure copper materials, copper-clad aluminum structureWeight reduction of about 40%, especially suitable for applications that require lightweight, such asPhotovoltaic welding ribbon, battery connectors, portable energy storage systems, etc.
- Reduce transportation and structural burden
- Improve the overall system cost performance
? Accurate size, suitable for automation
Ruichuang's small-size copper-clad aluminum flat wire adopts the independently developed precision rolling and online detection system to ensure that each roll of material meets the extremely high dimensional consistency and surface quality requirements:
- Thickness accuracy ±0.005mm
- Width accuracy ±0.02mm
- The curvature is very small, suitable for high-speed welding and SMT mounting process
? Excellent tinning and welding performance
The surface of the copper layer is suitable for various tin plating processes, has good wettability and solder adhesion, stable welding effect, no false welding, false welding, leakage problems, significantly improving the production yield.
