Copper-Aluminum Gasket Product Introduction

Core Advantages

1.Metallurgical Integrated Bonding No adhesive between copper and aluminum layers, firm combination, no delamination, no bubbling under long-term high temperature, high current and vibration working conditions, stable overall performance.

2.Excellent Electrical & Thermal Conductivity Copper surface ensures low contact resistance for current conduction; aluminum substrate reduces overall heat accumulation, effectively avoids overheating burnout at wiring joints.

3.Lightweight & Cost Optimization Replace full copper gasket to greatly reduce raw material cost and overall component weight, suitable for mass production cost control of new energy vehicles and energy storage equipment.

4.Strong Machinability & Sealing Performance Easy to cut, punch, bend and drill molding. Flat surface with high smoothness, good compression resilience, excellent sealing effect for pipeline flange connection, anti-leakage of gas and liquid medium.

5.Good Anti-Oxidation & Anti-Electrochemical Corrosion Composite structure inhibits galvanic corrosion caused by direct contact of single copper and aluminum, prolong service life in humid, outdoor and acidic working environments.
