Many of the stuff you have at home are made of non-ferrous metals, from the vehicle in your garage to the wedding ring on your finger. These metals are unlikely to rust anytime soon. In fact, some of them may still have the smoothness and lustre they have had when you first bought them. Those preserved properties are proof that these metals were excellently polished and finished before being turned into the products they are now.
How Polishing Helps
Even non-ferrous metals like aluminium, copper, and chromium cannot evade the onslaught of aging and corrosion. They will become paler and less attractive over time, especially if they are constantly exposed to the elements. Polishing and finishing are done to restore their original decorative appeal as well as to improve their chemical properties. Polishing aluminium, for instance, will enhance not only the metal’s sheen but also its tarnish resistance and durability.
