Aluminium alloy composite plate for brazing, also known as brazing sheet, is a specialized multi-layer material engineered for high-strength, leak-proof joining in heat exchanger manufacturing. It typically consists of a core alloy (like 3003) clad on one or both sides with a lower-melting-point aluminium-silicon alloy (like 4045 or 4343).
Aluminium alloy composite plate for brazing, also known as brazing sheet, is a specialized multi-layer material engineered for high-strength, leak-proof joining in heat exchanger manufacturing. It typically consists of a core alloy (like 3003) clad on one or both sides with a lower-melting-point aluminium-silicon alloy (like 4045 or 4343). During the controlled atmosphere brazing (CAB) or vacuum brazing process, the clad layer melts and flows to form seamless joints without melting the core, creating strong, durable, and corrosion-resistant heat exchange components.

The integrated brazing clad layer eliminates separate filler metal application, simplifying assembly and reducing process steps.
Ensures strong, uniform, and leak-proof seams thanks to the controlled flow of the clad material during brazing.
Aluminum’s low density helps reduce the overall weight of thermal systems, contributing directly to improved energy efficiency.
Lowers material and labor costs by minimizing filler usage and enabling high-volume, automated brazing processes.
Aluminum alloys offer inherent oxidation resistance, often enhanced with treatments, ensuring long service life in demanding environments.
“Switching to aluminium alloy composite plate for brazing was a game-changer for our heat exchanger production, especially for EV battery cooling plates and radiators. The consistency and quality of the brazed joints are outstanding, which significantly improved product reliability. It simplified our assembly line, cutting processing time, and the lightweight property is a major plus for vehicle efficiency. This material has become indispensable for our high-performance thermal management solutions.”
