For example, aluminum transforms and forms a trioxide of aluminum oxide, when it is burned in oxygen. Aluminum … The reaction leads to the formation of manganese and aluminum dioxide. Aluminum alloys differ based on their types and percentages of alloying elements. Boiling point: This melted solution when further heated, it starts to boil at 2470°C, 4478°F. Aluminium properties differ between grades depending on the alloy present giving each grades certain, unique characteristics. Hence they are called amphoteric oxides. It is well tolerated by animals and plants and hence it is less toxic. Nowadays in advanced countries, aluminum became the important construction material for buildings especially for industrial buildings along with brick, cement and steel. It is very reactive so that in the atmosphere a thin but equally protective oxide layer forms rapidly. Melting point: When heated, aluminum starts to melt at a temperature of 660.3°C or 1220.5°F.
