Types 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. In most cases, metals of desirable characteristics only are compressed into a single metal. It is important to note this new formed clad metal has better characteristics, such as 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. Some of the common types of clad metals are overlay clad and inlay clad. Inlay clad metals are created by combining precious metals like platinum, silver, and gold with substandard metals like brass, stainless steel, and copper. It is important to note that when bonding the cheaper and precious metals together, the precious metal can be positioned where needed.Inlay clad metals are denser, harder, and more resistant to wear. These desirable characteristics of the new metals ensures that there is an optimal level of 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. 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. Of important to know is that overlay clads are customized to fit certain industrial conditions.

These two types of clad metals have different forms. The factors determining the form a clad metal will have include clad sheet, clad wire, clad plate, clad rod, and clad tube. The form of the clad metals in turn dictate the cladding process, such as co-rolling, diffusion bonding, casting, co-extrusion, heavy electroplating, and heavy chemical deposition.

There are certain benefits of using clad metals.
The first benefit is a clad metal has a better appearance. Secondly, when using clad metals you will assured of higher resistance to corrosion and wear. Clad metals have appealing thermal and electrical properties. Clad metals have found their way in industrial applications. 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.

You must carry out special inspections, which are design to check whether there are any cracks in the weld joints. This is very important since the sides of the clad metals might be exposed to corrosion. The second precaution you must adhere to is preventing any absence of fusions, incomplete penetrations, and undercuts in the clad metals.
