What is metal clad plate and its application area?

 Metal clad plate is formed by using various composite technologies to realize metallurgical bonding of metals with different properties at the interface. It can greatly improve the thermal expansion, strength, toughness, abrasion resistance, corrosion resistance, electrical properties, magnetic properties and many other properties of a single metal and thus is widely used in petroleum, chemical, shipping, metallurgy, electric power, water conservancy, transport, environmental protection, food, pharmaceutical and other industrial fields. In addition to its structural and functional characteristics, metal clad plate can save the use of precious metals and significantly reduce the cost of various equipment materials.

 Common metal clad plates are: titanium-steel clad plate, copper-steel clad plate, titanium-zinc clad plate, titanium-nickel clad plate, nickel-steel clad plate, copper-aluminium clad plate, nickel-copper clad plate and so on.  Metal clad material technology can combine different materials and utilise the advantages of each. It can save precious metal materials and meet some performance requirements that a single metal can not meet. For example, the pressure vessels are made of stainless steel - steel clad plate, its base material is general carbon steel (Q245R, Q345R, etc.) with good mechanical properties and clad layer is stainless steel (304, 316L, etc.) with good corrosion resistance. The two are usually welded together by explosion welding. Just need a few millimetres of the high-priced stainless steel and almost no change to the various mechanical properties of the base material. It can replace imports and fill the gaps in the country and has a wide range of applications, good economic and social benefits, which is easy to get all aspects of support and help.

The heterogeneous metal clad materials also improve the development potential of traditional metal composites for its performance, lower cost and a wide range of applications. With the strengthening of the implementation of environmental protection industrial policy, the application of rare metal composites in electric power flue gas desulphurisation equipment continues to grow. While the chemical industry investment localisation is greatly accelerated, which also provides a good opportunity for its development.
