Copper Clad CAC-3PLY from CS-Tech is a tri-layer composite material with a copper-aluminum-copper structure, using 99.99% pure copper for both outer layers and an aluminum core. This configuration delivers 70% IACS electrical conductivity while reducing weight by 40% compared to solid copper, making it ideal for high-current applications where mass matters. The material is specifically engineered for battery module busbars in electric vehicles and energy storage systems, balancing conductivity with cost efficiency.
The composite leverages the conductivity of copper and the lightweight properties of aluminum, achieving a specific gravity of 3.65 against copper’s 8.95. Typical industry applications include EV battery packs, motor stators, and busduct systems, where the material’s antibacterial properties and volume-to-weight ratio provide additional value. Standard sheet and strip forms are available, with thicknesses commonly ranging from 0.1 mm to 3.0 mm for busbar fabrication, though exact dimensions should be confirmed with the supplier.
Manufacturers in the automotive and energy sectors source CAC-3PLY for its ability to replace copper without sacrificing performance, cutting material costs by up to 30%. Buyers should verify the clad ratio, surface finish, and mechanical properties such as tensile strength and elongation, which are critical for busbar bending and assembly. CS-Tech’s offering is positioned for OEMs requiring consistent conductivity and lightweighting in high-volume production runs.

Before ordering CAC-3PLY from CS-Tech, verify the exact clad ratio, electrical conductivity, and mechanical properties to ensure they meet your application’s requirements. Request material test reports and certifications for each batch, as these documents confirm compliance with your technical specifications. Check that the supplier’s manufacturing process aligns with your quality standards, particularly for automotive or energy storage applications where traceability is critical.
Confirm logistics details such as lead time, which can vary based on order volume and current production schedules. CS-Tech’s location in Busan offers advantages for sea freight, but clarify Incoterms to determine responsibility for shipping costs, insurance, and customs clearance. Typical Incoterms for such materials include FOB Busan or CIF to the buyer’s port. Payment terms should also be negotiated upfront, with common options being TT (telegraphic transfer) or LC (letter of credit).
Quality checks should include visual inspection for surface defects, dimensional verification using calipers or micrometers, and electrical conductivity testing. For busbar applications, perform bend tests to ensure the material can withstand forming without cracking. Request a pre-shipment inspection report from CS-Tech or a third-party agency to validate the material’s condition before dispatch. Additionally, ensure all documentation, including mill test certificates and RoHS compliance statements, accompanies the shipment.
