Chemistry of Metals and Alloys

A flashbulb is made up of a base, either metal or glass, a glass envelope usually coated on the interior and exterior with a plastic safety coating, primer paste, a tungsten igniter filament, a filling of shredded aluminum or other alloys with aluminum and oxygen. It fires when a voltage of 3-30V is applied to the ignition filament.

It is an alloy of aluminum that contains copper, manganese, magnesium, iron, and silicon and is resistant to corrosion by acids and sea water.Duralumin alloys are relatively soft, ductile, and workable in the normal state; they may be rolled, forged, extruded, or drawn into a variety of shapes and products. Their light weight and consequent high strength per unit weight compared to steel suit them for aircraft construction.

Magnesium is used in fireworks because when it is ignited in air, it burns with a white flame.

Duralumin is an alloy of aluminium, copper, magnesium and manganese. It is used in making bodies of aircraft.

Cobalt oxide is used to prepare blue glass.

A homogeneous mixture of a metal with a non-metal is called an alloy.

Galvanised iron is coated with zinc.

Yes, it is the correct answer. Aluminium is the most abundant metal in the Earth's crust. Percentage of aluminium in the Earth's crust is 8%.

Silver is less reactive than copper in the reactivity series, so it cannot displace copper from a copper sulphate solution.
