Non-ferrous metals in their pure state are employed in the manufacture of aircraft structures to a very limited extent as compared to their use in the alloyed forms. The properties and uses of non-ferrous metals commonly used in pure state are given below:
Aluminum
Properties: Light, ductile, soft, malleable, corrosion resistant, high electrical conductivity. Work hardens.
Uses: Aircraft fairings, fuel tanks, tubing, rivets and unstressed structures. Used extensively in light alloys.
Cadmium
Properties: Corrosion resistant.
Uses: Anti-corrosive plating, fusible alloys and bearing metals.
Chromium
Properties: Hard brittle, corrosive resistant.
Uses: Ann-corrosive plating, alloyed with steel and other metals.
Copper
Properties: Tough, ductile, malleable, high thermal and electrical conductivity. Fair corrosion resistance. Work hardens.
Uses: Tubing, electrical conductors, rivets, nails, gauze. Used extensively in light alloys and bearing alloys.

Lead
Properties: Soft, Plastic, malleable, acid resistant.
Plates in lead-acid accumulators. Cable sheathing, protective linings, ballast. Alloyed with tin and bearing alloys.
Magnesium
Properties: Soft, poor corrosion resistance, brittle, lighter than aluminium.
Uses: Used extensively in light alloys, and in small quantities as a deoxidant. Ignitable charge in incendiary bombs and flares, and used in photographic flash powder.
Nickel
Properties: Hard, ductile, corrosion resistant, withstands high temperatures.
Uses: Anti-corrosive , plating; Used in ferrous and non-ferrous alloys.
Zinc
Properties: Soft, ductile, malleable
Uses: Anti-corrosivc plating. Constituent of brass and other alloys.
Tin
Properties: Soft, ductile, malleable corrosion resistant.
Uses: Anti-corrosive plating. Important constituent of solder.
Manganese
Properties: Hard, brittle metal having a reddish or greyish tinge.
Uses: Used in the preparation of manganese steel which is used where parts are exposed to great wear and tear, example: railway tracks.
