Benefits of Clad Metals
A metal that has been combined with a layer of a different type of metal is referred to as a clad metal. Two metals are usually combined so as to get a single type of metal that has better characteristics. Usually, metals with desirable characteristics are bonded to form a single alloy. Such a clad metal boasts of better characteristics like lower porosity, better formability, and higher resistance to corrosion. Cladding of metals is possible through several procedures like bonding, rolling, pressing, diffusion, and extrusion.
Clad metals are categorized on the basis of the materials making them and the bonding process used to build them. The different categories of clad metals are inlay clad and overlay clad. Inlay clad metals are achieved by bonding precious metals like silver, gold, or platinum with cheaper metals like copper, brass, or stainless steel. During this process, the precious metals used are put in a position you require them to be.This resulting product possesses better characteristics like more resistance to wear and tear and become harder and denser. Optimum bond integrity is achieved through these characteristics.
Overlay clad metals are those clad metals that are created by a metallurgical technique, which bonds together different metals under high pressure and heat. The overlay clads can either be a single clad, which as two layers, a double clad with three layers or even one with seven layers. Another important fact about overlay clads is that they can be customized to match the requirements of specific industries.
Both overlay and inlay clad metals possess different forms. Elements, such as clad sheet, clad wire, clad plate, clad rod, and clad tube, determine the form of clad metals. The shape or form of each clad metal determines the process of cladding, such as co-rolling, diffusion, casting, heavy electroplating, co-extrusion, and heavy chemical deposition.
There are certain advantages associated with clad metals.
Cladding creates clad metals that have better outward appearance. Secondly, when using clad metals you will assured of higher resistance to corrosion and wear. The good electrical and thermal properties into them makes them better metals. Clad metals have found their way in industrial applications. They are used in industrial applications since their ability to add value. Clad metals are used in specific industrial applications like cryogenic processing, power generation, shipbuilding, aluminum smelting, petroleum refining, and chemical processing among many others.
Enjoying these benefits demands special inspection of nay cracks in the weld joints. The fact that clad metals are exposed to corrosion makes it necessary for the regular special inspections. Furthermore, quality control measures must be applied during the cladding process so that there are no undercuts, incomplete penetrations, and lack of fusions in the clad metals.
