Would you like to give back to the community by fixing a spelling mistake? Because it's reasonably strong, but not too heavy, your aluminum bicycle won't break and won't be too difficult to ride. It is mostly used in an alloy with another metal, this means it is mixed with another metal to produce another compound that has a certain desirable characteristic - like stainless steel.

    In chemistry and manufacturing, electrolysis is a technique that uses a direct electric current Nevertheless, electrolysis, as a tool to study chemical reactions and obtain pure elements, Electrodes of metal, graphite and semiconductor material are widely used.

    Oxidation of ions or neutral molecules occurs at the anode.
    Therefore, aluminum is much more expensive than other metals that are easier to extract like ironbut its desirable characteristics mean that it is still widely used.
