Copper Clad CMC-3PLY
Copper Clad CMC-3PLY from CS-Tech is a tri-layer composite featuring copper outer layers bonded to a mild steel core, designed for electric contact applications in circuit breakers such as ELB and MCCB. The material offers 35% IACS electrical conductivity, a 10% weight reduction compared to solid copper, and a 35% cost reduction, making it a practical alternative to ETP copper, brass, or phosphor bronze. Its specific gravity of 8.07 reflects the balance between copper content and steel core efficiency.
The composite’s structure provides enhanced strength and arc resistance, critical for breaker contacts where wear and thermal stress are common. Typical industry use includes sheet or strip forms for OEM production of low-voltage circuit breakers, where the material’s conductivity and durability are essential. Standard thicknesses for such applications range from 0.2 mm to 2.0 mm, though exact specifications should be confirmed with CS-Tech.
Manufacturers in the electrical and construction sectors source CMC-3PLY for its ability to replace higher-cost materials without compromising performance. The material is also being explored for home appliance contacts and other high-current applications. Buyers should verify the clad ratio, surface finish, and mechanical properties such as hardness and elongation to ensure suitability for their specific use case.
| Material Composition | Copper + Mild Steel + Copper (Tri-Layer Clad) |

CS-Tech operates from Busan, South Korea, at 87-7, Noksansandan 261-ro, providing a strategic location for exporting copper clad materials to global markets. The company’s focus on copper-mild steel composites demonstrates its specialization in electrical contact materials, particularly for circuit breaker manufacturers. Busan’s port infrastructure supports efficient shipping, making CS-Tech a viable partner for buyers in Europe, Asia, and the Americas.
With a harbor trust tier, CS-Tech meets the baseline verification for export readiness, though its response rate and average response hours are currently unrecorded. The supplier’s profile emphasizes its technical expertise in clad materials, catering to OEMs in the electrical and electronics industries. While the company does not advertise extensive client lists or certifications, its product specifications align with standard industrial requirements for breaker contacts.
CMC-3PLY is a tri-layer clad material combining Copper on both outer surfaces with a Mild Steel core, designed specifically for electric contact applications in ELB and MCCB circuit breakers. This composite offers superior conductivity and arc resistance compared to solid brass or phosphor bronze alternatives, while reducing raw copper usage through the efficient sandwich construction. Widely sourced from Asian manufacturers for global distribution, it meets standard industrial specifications and is traded in sheet or strip form for breaker OEM production.

Sourcing Copper Clad CMC-3PLY from CS-Tech - South Korea Import Guide
Prior to ordering CMC-3PLY from CS-Tech, verify the exact clad ratio, electrical conductivity, and mechanical properties to ensure they align with your circuit breaker or contact application requirements. Request material test reports and certifications for each batch, as these documents are essential for validating compliance with your technical specifications. Check that the supplier’s manufacturing process meets your quality standards, particularly for applications where reliability is non-negotiable.
Clarify logistics details such as lead time, which may vary based on order volume and production schedules. CS-Tech’s location in Busan provides advantages for sea freight, but confirm Incoterms to determine responsibility for shipping, insurance, and customs clearance. Common Incoterms for such materials include FOB Busan or CIF to your designated port. Payment terms should be negotiated in advance, with options such as TT or LC being standard for international transactions.
Conduct quality checks including visual inspection for surface defects, dimensional verification, and electrical conductivity testing using a four-point probe or eddy current method. For breaker contacts, perform wear tests to assess the material’s durability under repeated switching. Request a pre-shipment inspection report from CS-Tech or a third-party agency to confirm the material’s condition before dispatch. Ensure all documentation, including mill test certificates and compliance statements, is provided with the shipment.
