7. Brief of metal cladding material

        Metal clad material is a kind of material which combines different metals together with metallurgical bonding at the interface.Clad material greatly improves thermal expansion,strength,fracture toughness,impact toughness,abrasion resistance,electrical properties,magnetic properties and many other performances of single metal material. As a result, this material is widely used in petroleum,chemical,shipbuilding,metallurgy,mining,machinery manufacturing,electricity,water conservancy,trqansportation,environmental protection,pressure vessel manufacturing,food,brewing,pharmaceutical and other industry fields. Aluminum based multi-metal clad material is a clad material which clad aluminum,aluminum alloys with other metals. In theory,aluminum and aluminum alloy can be cladded with most metals.
        Typical applications for aluminum based multi-metal clad material
        Aluminum clad steell material
        The cladding of special steel and aluminum alloy combines the strength of steel and the excellent heat transfer performance of aluminum alloy, and makes brazing between steel and aluminum fins possible, which brings great changes to the design of the large cooling system. So this material is largely used in single-row type air-cooling condensers (ACC) for power station which is highly recommended by our government every year. The ACC system could save billions of tons of water for the whole country.
        Bushing Materials
        Babbitt (high tin alloy)-Steel clad material is excellent self-lubricated material, and is the important component of sliding bearing, which is necessary in the power system of cars,ships and machines.
        Aluminum clad stainless steel material
        The combination of stainless steel and aluminum alloy offers stainless steel better heat transfer performance and greatly reduces the material weight,at the same time,the corrosion resistance and strength is still good.This kind of material is a good material form manufacturing energy-saving cookers,and can dramatically reduce the weight of the vehicles when used for auto parts.
        Aluminum Clad copper material
        Copper is the best heat transfer and electric conductive material, and aluminum is second only to it. So the combination of the two can maintain good electrical conductivity and thermal conductivity meanwhile reducing weight and cost significantly.
