CHICAGO – The types of metals used in wide ranges of products have evolved in recent years, trending toward greater use of alloys and new kinds of alloys as manufacturers strive to make things that are stronger and lighter weight. According to an industry insider, this shifting landscape of machining creates challenges in the formulation of metalworking fluids.
Much of the evolution in metals choices has been spurred by efforts to improve fuel economy – both in on-road automobiles and in other types of equipment. If a manufacturer switches to a metal that is stronger – which can be measured in different ways, such as torsional rigidity and bending rigidity – then they often can use less of the metal, reducing mass and thereby allowing better fuel economy.
