What is the difference between hard oxidation and ordinary oxidation of aluminum products?

Overall, the difference between hard oxidation and ordinary oxidation boils down to one thing—extra oomph! With hard oxidation, you get a thick oxide film that’s tougher than nails, providing unparalleled protection, insulation, and wear resistance. Ordinary oxidation, on the other hand, offers a sleek and compact finish, perfect for those who prefer a more refined aesthetic.
