Treatment (In House Facility):
Heat Treatment is the process whereby controlled heating and cooling is
used to alter the physical & mechanical properties of metals without
affecting any change in the shape of the objects. Heat treatment process is used
to increase material strength and also to improve machining, formability &
restore ductility. Heat treatment process allows for the improvement in product
performance through improvement in material characteristics.
Metallurgy of Heat Treatment of Aluminum Alloys
Aluminum and its Alloys are used in a variety of cast a wrought forms and
conditions of heat treatment. Forging, extrusions, sections, etc., are
examples of wrought products, while sand, gravity and pressure die castings
are generally adopted casting methods.
It has been the practice of Designers to specify heat treatment to enhance
mechanical properties, hardness and machinabilty. Only certain Aluminum
Alloys containing alloying elements like CU, Si, Mg and Zn in certain
specific percentages can be heat treated to have desired mechanical
properties. Other non heat treatable alloys can at the most be annealed to
facilitate forming operations.
The various alloying elements mentioned above have limited solubility in
solid state and this increase with increased temperature.
Solution Heat Treatment
This involves heating of Aluminum alloy to a particular temperature for
sufficient time so that the alloying elements go into solid solution and
forma single phase. The factors which affect the final properties of the
alloy are soaking temperature, soaking time and cooling rate.
The Soaking temperature depends on various phases which are present in
alloys. Each phase will dissolve in solid solution at different rates. The
soaking time is based on the rate of dissolution of alloying elements into
solid solution. It also depends on the conditions under which the alloy is
cast. Sand cast parts have coarser structure than permanent mould casting.
Hence Aluminium Sand Castings take time for dissolution of phases necessitating longer
Commonly used T6 Heat Treatment Process:
Coating is the process whereby
components and products are coated or plated through various methods. The
coating processes generally utilized by us include :
This refers to the process whereby a component or product is coated with
paints of various types. These paints are chosen as per the requirements of
customers and their diverse properties such as water resistance, chemical
resistance, abrasion resistance etc.
Plating refers to the process whereby a metal salt solution is deposited
onto metal or conductive surfaces. This includes chrome plating, that is
conducted as per the specifications of customers, & powder coating which
is conducted as per specifications for colors etc. as required by the
Our coating services adhere to all certifications and quality requirements
of our customers.
