Properties Aluminium is a very good conductor of electricity and heat.It is light and strong. It can be hammered into sheets or pulled out into wires ().It is a highly reactive metal, although it is corrosion resistant.Aluminium prevents corrosion by forming a small, thin layer of aluminium oxide on its surface..

University of Calcium Chloride by Manufacturers

Calcium chloride can be used to quickly treat Calcium Channel Blocker toxicity, from the side effects of drugs such as Diltiazem (Cardizem) - helping avoid potential heart attacks. The aqueous form of calcium chloride is used in genetic transformation of cells by increasing the cell merane permeability, inducing competence for DNA uptake (allowing DNA fragments to enter the cell more readily).

calcium | Definition, Properties, & Compounds | Britannica

Calcium constitutes 3.64 percent of Earth’s crust and 8 percent of the Moon’s crust, and its cosmic abundance is estimated at 4.9 × 10 4 atoms (on a scale where the abundance of silicon is 10 6 atoms). As calcite (calcium carbonate), it occurs on Earth in limestone, chalk, marble, dolomite, eggshells, pearls, coral, stalactites, stalagmites, and the shells of many marine animals.
