Is Frosted Aluminum Anodized Aluminum?

Not, grinding aluminum is the use of a grinding machine (with stainless steel beads, etc.) to knock off the metal processing marks on the surface of aluminum, forming the surface of the frosted texture. Anodized aluminum is the chemical oxidation sealing of aluminum to form a dense oxide film on the surface of aluminum to effectively protect the aluminum substrate from external water, gas and other corrosion.
