Aluminium (n): A light, silvery metal extracted from bauxite, and a chemical element. Its symbol is Al with an atomic number of 13.e.g.: Aluminium is widely used in aircraft production in alloy forms.


Copper: (n): A reddish-brown coloured metal largely used in thermal conductivity. Its symbol is Cu with an atomic number of 29.

e.g. Copper is widely used in electrical wires because of its high conductivity.


Magnesium (n): A light flammable silvery metal and a chemical element. Its symbol is Mg with an atomic number of 12.


e.g.: Magnesium is widely used in jet engine parts, rockets, missiles.

Titanium (n): A strong, corrosion-resistant transition metal. Its symbol is Ti with an atomic number of 22.

e.g. Titanium is widely used to make light alloys for aircraft materials.


Brass (n): Brass is an alloy of copper and zinc.

e.g.: Because of its bright gold-like appearance, it is generally used for decoration, such as doorknobs, musical instruments and zippers.


Zinc (n): A bluish-white chemical element. Its symbol is Zn with an atomic number of 30.

e.g.: Zinc is widely used zinc planting because of its high corrosion-resistance.


Bronze (n): Bronze is an alloy consisting primarily of copper, usually with tin as the main additive.

e.g.: Bronze is widely used in boat and ship fittings for its toughness and resistance to salt water corrosion. It is also used for sculpture, coin and ornament production.


Tin (n): A silvery or grey coloured chemical element. Its symbol is Sn with an atomic number of 50.

e.g.: Tin is widely used as a solder in the form of an alloy with lead. Also, it is used in preserving food.


Lead (n): A soft grayish-coloured chemical element. Its symbol is Pb with an atomic number of 82.

e.g.: Lead is widely used in batteries, bullets, weights and as a radiation shield.


Silver (n): A soft, precious, white transition metal. Its symbol is Ag with an atomic number of 47.

e.g.: Silver is widely used in jewellery, and mirror and coin production.


Precious metal (adj. Phr.): A precious metal is rare naturally occuring metalic chemical element of high economic value.

e.g.: Gold, silver, platinium and iridium are well-known precious metals.


Gold (n): A dense, soft, shiny, malleable and ductile metal. Its symbol is Au with an atomic number of 79.

e.g.: Gold is an excellent conductor and is highly corrosion-resistant.

e.g.: It is widely used in jewellery and as a heat shielding material.


Ductility (n): Ability of metals and alloys to retain strength and freedom from cracks when shape is altered.

e.g.: Ductility is often characterized by the material's ability to be stretched into a wire.


Plate (n): A shaped and fitted surface of a metal.

e.g.: Plates are used for decorative purposes. It is also used in construction materials.


Galvanize (v): To cover of iron or steel surfaces with a protective layer of zinc.

Word formation: Galvanizing (n), galvanized (adj) e.g.: Galvanizing is applied with zinc to iron or steel in order to

protect from corrosion.


Molten (adj): being in a state of fusion especially when the liquid state is produced by a high degree of heat as molten iron.

Synonyms: melted (adj), melting (adj)


Electroplate (v): To coat an object with a thin layer of metal using electrosis.

Collocation: Electroplated objects (adj. phr.)Word formation: Electroplated (adj)


Electroplating

Electrolyte (n): A substance that, in solution or when molten, ionizes and conducts electricity.


Plating with non-ferrous metals A piece of zinc is also placed in electrolyte, and it is connected to the positive terminal (+) of the supply. This then becomes the anode (the positive side). An electric current then flows between the pieces of metal, through the electrolyte. This causes a chemical reaction, which deposits zinc on the cathode, plating the component.

Terminal (n): the mechanical device by which an electric connection to an apparatus is established the point where current enters or leaves any conducting component in an electric circuit

Collocation: Positive terminal (+)Negative terminal (-)


Cathode (n): The electrode or terminal by which current leaves an electrolytic cell voltaic cell battery etc.

e.g.: Cathode is the negative terminal electrode or element of an electron tube or electrolytic cell.


Anode(n): The electrode or terminal by which current enters an electrolytic cell voltaic cell battery etc.

e.g.: Anode is the positive terminal electrode or element of an electron tube or electrolytic cell


Anodize (v): to coat a metal especially magnesium or aluminum with a protective film by electrolytic means.

Word formation: Anodization (n)


Plating with non-ferrous metals A related process, called anodizing, is used to protect aluminium. The component to be anodized is connected to the positive terminal (to become the anode) and placed in an electrolyte, with a cathode. As electricity flows, aluminium oxide is deposited on the anode. As this is harder than aluminium metal, it provides protection.

Aluminium oxide (n): Aluminium oxide is a chemical compound of aluminium and oxygen with the chemical formula Al2O3.
