Aluminum Alloys – Effects of Alloying Elements

Calcium has very low solubility in aluminum and forms the intermetallic CaAl 4. An interesting group of alloys containing about 5% Ca and 5% Zn have superplastic properties. Calcium coines with silicon to form CaSi2, which is almost insoluble in aluminum and therefore will increase the conductivity of commercial-grade metal slightly.

Calcium - Wikipedia

Calcium is a chemical element with the syol Ca and atomic nuer 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth''s crust, and the third most abundant metal, after iron and aluminium. The most common calcium compound on Earth is calcium …

Thallium - Wikipedia

Thallium is a chemical element with the syol Tl and atomic nuer 81. It is a gray post-transition metal that is not found free in nature. When isolated, thallium reseles tin, but discolors when exposed to air.Chemists William Crookes and Claude-Auguste Lamy discovered thallium independently in 1861, in residues of sulfuric acid production. Both used the newly developed method of flame
