4343/3003 aluminum composite plate

“4343/3003  aluminum composite plate” is an aluminum plate material. “4343” and “3003” are the grades of aluminum alloy.

4343 aluminum alloy belongs to aluminum-silicon alloy. It contains elements such as silicon (Si). Its main feature is that it has a low melting point and can play a good brazing role when compounded with other materials (such as 3003 aluminum alloy).

3003 aluminum alloy is an aluminum alloy with manganese (Mn) as the main alloying element. It has good corrosion resistance, formability and weldability, and its strength is higher than pure aluminum.

Aluminum composite plate is a plate formed by compounding these two different grades of aluminum alloys through a specific processing technology.

Material characteristics

Corrosion resistance: 3003 aluminum alloy itself has good corrosion resistance, and the double-layer structure can further improve its corrosion resistance to a certain extent, extending the service life of the material.
Strength and formability: Due to the presence of 3003 aluminum alloy, the double-layer aluminum plate has good strength and can withstand certain external forces. At the same time, its formability is also good, and it can be made into various shapes through bending, stamping and other processing methods.

Thermal conductivity: The thermal conductivity of 4343/3003 double-layer aluminum plate is moderate. In some application scenarios where insulation or heat dissipation needs to be considered, this thermal conductivity can be met through reasonable design.

Application fields

Automobile manufacturing: 4343/3003 aluminum composite plate has a wide range of applications in the automotive manufacturing industry, such as the manufacture of heat exchange system components such as automotive radiators, condensers, and evaporators.

New energy vehicles: In the field of new energy vehicles, this material is used in the manufacture of heat dissipation components such as liquid cooling plates to meet the heat dissipation needs of components such as power batteries.

Engineering/energy storage equipment radiator: The good thermal conductivity and processability of 4343/3003 double-layer aluminum plate make it an ideal material for radiators, which can quickly transfer the heat generated by electronic components, reduce the temperature of the equipment, and ensure its normal operation.
