Types of Light Weight Non-ferrous Metals

Light weight Metals:

Light weight of certain non-ferrous metals is of special importance in aircraft and space industry. Zinc, tin and lead (with low melting points) are utilized in special applications. Tungsten, molybdenum and chromium are utilized in products that have got to resist high temp. Nickel and cobalt also are suitable as heat resistant alloys. Precious metals (with high cost) aren't only utilized in jewelry, but also in many applications requiring high electrical conductivity and corrosion resistance.

The border of light and heavy metals is around 5000 kg/m3. Metals densities below 5000 kg/m3 are called light metals. The lightest metal is Lithium (density 530 kg/m3) whereas the heaviest metal is Osmium (with density of 22500 kg/m3). Steel has a density of 7800 kg/m3.

Aluminum (Al):

 Aluminum

It is probably the most important non-ferrous metal. It has outstanding physical properties (e.g. light weight, high thermal and electrical conductivity, and corrosion resistance). It is suitable for all machining, casting and forming operations.

Magnesium (Mg):

 Magnesium

It is the lightest engineering material. The combination of rarity and good mechanical strength has made it one among the foremost specified materials in aircraft, space, portable power tools, luggage and similar applications as competing with the aluminum alloys.

Titanium (Ti):

 Titanium

It is utilized in corrosive environments or in applications of sunshine weight, high strength and nonmagnetic properties. It has good heat strength as compared with other light metals.

Beryllium (Be):

 Beryllium

Beryllium is a recently emergent material having several unique properties of low density (one-third lighter than aluminum), high modulus-to-density ratio (six times greater than ultrahigh-strength steels), high melting point, dimensional stability, excellent thermal conductivity and transparent to X-rays.
