  2. Properties of metals, metalloids and nonmetals - Wikipedia

    en.wikipedia.org/wiki/Properties_of_metals...

    The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.

  3. Zinc - Wikipedia

    en.wikipedia.org/wiki/Zinc

    Zinc is a chemical element with the symbol Zn and atomic number 30. It is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table.

  4. Amorphous metal - Wikipedia

    en.wikipedia.org/wiki/Amorphous_metal

    An amorphous metal (also known as metallic glass, glassy metal, or shiny metal) is a solid metallic material, usually an alloy, with disordered atomic-scale structure. Most metals are crystalline in their solid state, which means they have a highly ordered arrangement of atoms. Amorphous metals are non-crystalline, and have a glass-like structure.

    They have the lowest melting points among all transition metals. [8] Zinc is bluish-white and lustrous, [9] though most common commercial grades of the metal have a dull finish. [10] Zinc is also referred to in nonscientific contexts as spelter. [11] Cadmium is soft, malleable, ductile, and with a bluish-white color. Mercury is a liquid, heavy ...

  6. Chemical coloring of metals - Wikipedia

    en.wikipedia.org/wiki/Chemical_coloring_of_metals

    Chemical coloring of metals is the process of changing the color of metal surfaces with different chemical solutions. The chemical coloring of metals can be split into three types: electroplating – coating the metal surface with another metal using electrolysis. patination – chemically reacting the metal surface to form a colored oxide or ...

  9. Solderability - Wikipedia

    en.wikipedia.org/wiki/Solderability

    The metals in the good category require a large amount of heat therefore oxidation is an issue. To overcome this a flux is required. For carbon steel , low alloy steel , zinc , and nickel the presence of sulfur creates a brittle joint; lower temperatures are used to minimize this problem.
