Apr 14, 2012· Compared to many other metals and alloys and many other materials, such as carbides, ceramics and sintered carbides, aluminum and its alloys are low in strength and hardness. Aluminum is a soft, silvery metal with a facecentered cubic crystal structure, a hallmark of ductile metals. Its softness makes it somewhat difficult to prepare but the alloy is not sensitive to problems that plague ...
Most meats, fish, fruits, and vegetables naturally contain traces of aluminum. Cooking foods in aluminum pots and pans or in aluminum foil can increase their aluminum content. Aluminumcontaining antacids, food additives, and antiperspirants are additional sources of exposure. Drinking water is not usually a significant source of aluminum exposure.
