Gas Turbine Engines
The gas turbine is an internal combustion engine that uses air as the working fluid. The engine extracts chemical energy from fuel and converts it to mechanical energy using the…
Hardness Testing
Hardness testing is a method of determining the results of heat treatment as well as the state of a metal prior to heat treatment. Since hardness values can be tied…
Other Alloys
Dow metal It is a magnesium-base alloy, containing 90% Mg, 10% Al and a small addition of Mn. Small additions of cadmium and copper increase its thermal conductivity considerably. It…
Bearing Metals

Nickel Alloys
German Silver It is also known as Ni-silver. It contains 60% Cu, 30% Ni and 10% Zn. It is very ductile and malleable and displays silvery appearance. It is used…
Aluminium Alloys
Duralumin. It contains 4% Cu, 0.5% Mg, 0.5% Mn and the rest aluminium. It has high tensile strength, comparable with mild steel, combined with the characteristic lightness of aluminium. It,…
Bronzes
Bronze is basically an alloy of copper and tin. In general, it possesses superior mechanical properties and corrosion resistance than brass. Those containing upto 8% tin are called working bronzes.…
Non-Ferrous Alloys
Due to poor physical and mechanical properties and high costs the nonferrous metals are seldom used in their pure state. But their alloys carry very good physical and mechanical properties…
Non Ferrous Metals & It’s Alloys
Non-ferrous metals are those which do not contain iron as the base material. The most commonly used non-ferrous metals in wokshop are aluminium, copper, lead, tin, nickel and zinc. They…
Aerodynamics
Aerodynamics is the study of forces and the resulting motion of objects through the air. Studying the motion of air around an object allows us to measure the forces…
