The growth of aluminum usage is primarily driven by the automotive and transportation industry, followed by aerospace and defense and marine. From 2008 to 2018, global aluminum production grew at a compounded annual growth rate (CAGR) of 4.8%, whereas global steel production grew at a CAGR of 3.0%. Although total production of steel is higher than the production of aluminum currently, the growth rate of aluminum production is about 60% higher than that of steel.
Although the properties of specific aluminum alloys can vary widely, it is safe to make the following generalizations: Aluminum Usage IncreasesĪluminum used in industry is typically not the pure element but rather one in a range of families of aluminum alloys, depending on the end use. This then leads to new aluminum grinding products with greatly improved grinding speeds and longer-lasting performance, without the need for waxes or lubricants. Typical right-angle grinder wheels designed for steel are not for use on aluminum because the wheel’s surface can rapidly become clogged with metal chips that stick to the abrasive.īy investigating the mechanisms by which metal chips can become stuck (loaded) to the abrasive wheel’s surface, strategies to avoid metal loading can be applied to the abrasive design. The lightweighting trends across the transportation sector bring the need for fast and efficient tools for grinding aluminum.
As a result, metal fabricators need new tools for working with this challenging material.Īluminum alloys offer improved strength-to-weight ratio when compared to traditional steel alloys. In recent years, transportation industries have increasingly turned to aluminum as they look to “lightweight” their products. Using an abrasive designed specifically for the task will yield the best results. Manually grinding aluminum workpieces can be challenging.
