4343/3003/4343 cladding aluminium foil fin

Specification Range

4343/3003/4343 is a kind of Three-layer aluminum alloy composite foil which is the most widely used aluminum-heat transfer material. It is the basic material for the preparation of automotive engine radiator, air conditioning condenser, intercooler and other heat exchangers. The outer 4343 subeutectic aluminum-silicon alloy is the brazing material connecting the fluid pipe to the heat fin, while the inner 3003 aluminum-manganese alloy is the bearing part of the heat fin.

Product features

With the development of market economy and continuous progress of science and technology, the aluminum fin material of power plant heat exchanger is gradually changed from the original aluminum foil and solder to the new aluminum alloy composite material, which has better welding performance. The advantages of higher fin strength and more stable heat exchanger at high temperature. New composite aluminum strip 4343/3003/4343, 4343 alloy double bread covering for the leather, new alloy 3003 for the core.
