4343 3003 4343 Aluminium Clad Strip for automobile radiator

In the automobile manufacturing industry, high-performance and high-efficiency heat dissipation systems are essential for the long-term stable operation of vehicles, and new radiator composite materials are leading the revolution. Traditional radiators mainly use metal materials, but new materials combine the thermal conductivity of metals with the lightweight and corrosion-resistant properties of composite materials, becoming the new favorite of the automotive industry, improving vehicle performance while promoting environmental protection and energy saving.

The key components of the automotive heat exchange system include condensers, evaporators, radiators, intercoolers, heaters and oil coolers. The core material of the automotive heat exchanger is brazed composite aluminum sheet and foil. Its process technology features are the use of rolling composite technology, coating one or both sides of the 3xxx series aluminum matrix (core layer) with 4xxx series brazing materials, and rolling them together on a hot rolling mill under high temperature and high pressure welding, and then cold rolling to the finished product.

Introduction to brazed composite aluminum sheet and strip alloys:

4343 Aluminum alloy: mainly used for cladding materials. It contains high silicon and provides good corrosion resistance and weldability. Usually used for the inner and outer layers of composite strips.

3003 Aluminum alloy: Mainly used for core material. It is an aluminum-manganese alloy with excellent corrosion resistance and formability, and excellent thermal conductivity.
