It’s not always easy to tell if rust has started to form on your magnesium alloy, as it’s often a slow, gradual process. Signs of corrosion may include visible streaks or discoloration on the metal surface, as well as crusty residue and pits in the material. Additionally, you may be able to feel the effects of rusting if there is an increased amount of friction when moving metal parts or objects made from your alloy.
