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. The main purpose of boding two different types of metals is to produce a metal that has better characteristics than a single metal. An important condition that must be adhered to is that the two different metals must have desirable characteristics for them to be cladded into one type of metal. Such a clad metal boasts of better characteristics like lower porosity, better formability, and higher resistance to corrosion. Clad metals are formed through processes like extrusion, diffusion, bonding, rolling, and pressing.
Clad metals are classified according to the types of materials used to form them and the bonding process as well. Some of the common types of clad metals are overlay clad and inlay clad. Inlay clad metals are achieved by bonding precious metals like silver, gold, or platinum with cheaper metals like copper, brass, or stainless steel. This process allows the precious metals to be placed where you want.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. By customizing overlay clads, industrial requirements are met.
These two types of clad metals have different forms. Elements, such as clad sheet, clad wire, clad plate, clad rod, and clad tube, determine the form of clad metals. 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 have found their way in industrial applications. Clad metals add high value in industrial applications. Some of these industrial applications include chemical processing, petroleum refining, aluminum smelting, shipbuilding, cryogenic processing, power generation, and metal production 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. Another important tip when cladding metals is to establish quality control measures, which will prevent any undercuts, absence of fusions, and incomplete penetrations in the clad metals.
