While high value metals like gold, silver, platinum and palladium are classified as precious metals, there is another very valuable category of metals known as Industrial metals. As the name suggests these metals have very critical industrial applications in a variety of industries. Copper, aluminium, nickel, lead and zinc fall under this category. As these industrial metals have largely industrial applications, their prices tend to fluctuate with the ups and the downs of the business cycle. Copper is one of the key industrial base metals with extensive applications in industry in sectors like construction, electric installations etc.
