Among the figures exhibits significant corrosion on aluminum and just how temperature and metal alloy affect around the corrosion attack. Aluminum will therefore more often than not function as the anode, the component which corrodes, in contact with different metals, but because of the oxide layer that is organic established Aluminum can be quite a called a passive material. Aluminum-oxide is nearly as tough as stone (1200 HV or more) in standard too skinny to increase the hardness of the aluminum metal itself. Another impression (of the lower teeth) is filled with plaster on the vibrating stand, as well as a pack of plaster is put on the worktop.
