Benefits of Clad Metals
Clad metals are simply metals that have been compressed with at least another type of metal. The main idea behind bonding two types of metals is to get one metal that works better than one type of metal. 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.
There are different types of clad metals, which are classified according to the type of bonding and materials used to make 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.The resulting clad metal becomes harder, denser, and more resistant to wear and tear. These characteristics are important since they promote optimal bond integrity.
Overlay clad metals are those clad metals that are created by a metallurgical technique, which bonds together different metals under high pressure and heat. It is important to note that overlay clads can be subdivided into a single clad with two layers, double clad with three layers, and overlay clads with seven layers. By customizing overlay clads, industrial requirements are met.
Both overlay and inlay clad metals possess different forms. The various forms of clad metals is dictated by factors like clad plate, clad rod, clad tube, clad sheet, and clad wire. An important fact about the form or shape of clad metals is that they determine the processes of cladding, like co-rolling, heavy electroplating, co-extrusion, diffusion, heavy chemical deposition, and casting.
The desirable characteristics of clad metals present certain benefits that one can enjoy.
The first benefit is a clad metal has a better appearance. With clad metals, the rate of resistance to wear and corrosion is higher. Furthermore, clad metals have good electrical and thermal properties. Clad metals are also used in industrial functions. Clad metals add high value in industrial applications. These industrial applications range from chemical processing, petroleum refining, aluminum smelting, shipbuilding, cryogenic processing, power generation, to metal production.
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. The second precaution you must adhere to is preventing any absence of fusions, incomplete penetrations, and undercuts in the clad metals.
