Can a bullet be stopped by foam?
It turns out that you can stop a projectile by making that foam out of metal. Just such a foam has been developed by North Carolina State University researchers, and at half the weight, it is more effective at stopping the trajectory of a.50 caliber bullet than the military's present armor, thick slabs of steel.
Will salt consume aluminum?
However, when there is salt in the water or air around the metal, aluminum is susceptible to corrosion. Even so, aluminum is a great material for outdoor products including boats, car wheels, patio furniture, railings, and light fixtures.
Is aluminum preferable to stainless steel?
Aluminum doesn't rust since it has strong anti-corrosion characteristics. However, stainless steel wins out in this situation because it has been added chromium, which gives it a protective film and high corrosion resistance. Additionally, stainless steel is non-porous, which increases its resistance to corrosion.
