Aluminum has a small density, high strength of stainless steel, and they have good corrosion resistance in many media. They are used more as decorative materials and cooking utensils. Composite materials with their compositions have both physical and chemical properties, and are a new type of structural materials with wide applications.
The manufacturing methods of Al stainless steel composites include rolling, friction welding and explosive welding. In comparison, the latter has a unique advantage in producing a wide range of products and large-scale products, especially aluminum-stainless steel Bimetal plates with different thickness ratios and large areas.

Stainless steel-aluminum-stainless steel bimetal plate have the advantages of light weight and excellent thermal conductivity of aluminum, high strength and corrosion resistance of stainless steel, as well as excellent deep drawing performance and low cost, so they have been widely used, such as advanced cooking utensils, vehicle parts, medical devices, pressure vessels, integrated circuit lead frames. Missile shell and aircraft auxiliary power plant.
AlMg5-stainless steel bimetal paltes sheets manufactured by explosive welding in cryogenic media; used in chemical machine manufacturing, atomic energy and cryogenic technology, and in vacuum-tight pipe joints for flight machinery, made of AlMg3-St37 steel with diameters of 12-150 mm.
In the aerospace industry, in order to make the materials with good low temperature performance and reduce the weight of the structure, the connection of the cryogenic container with liquid hydrogen and liquid oxygen and the outer pipeline is usually welded with different materials. When the weldability of two kinds of materials is very poor and the connection strength is required to be high, the pipe joints of different materials must be used for transition connection. The 304L stainless steel-Al-Cu-Mg alloy transition pipe joint manufactured by the explosive welding method of Henan Chalco has solved this problem.
