Generally Aluminium alloy type 6063 comes in the shape of sheets having thickness range from half a millimetre to 8 millimetre. These sheets are having a length of 8 feet. These are used for the engineering purposes in various industries. They come in different shapes also like foil or rectangle pieces. One has to see as per the use or the design of the fabrication to be undertaken.

Depending upon whether it is polished or not and its quality (purity of Aluminium) the rates will vary. Some manufacturers produce very high quality Aluminium alloy which will be a bit costly. In general the rates for the Aluminium 6063 grade will hover in the range of Rs 160 to 270 per Kg. It will also depend upon the quantity you are planning to purchase. If many students have to make an Aluminium frame or model for their project or assignment then it makes sense to club the purchase and ask the vendor for some discount on the bulk purchases.

The aluminium sheet is very much available in India. There are many manufacturers in India. HINDALCO is one of such companies. This company manufactures all varieties of aluminium. 6063 is very commonly available commercial grade. It will be available in sheet form with various thicknesses. The rate will be between Rs.200/- to Rs.300/- including taxes. Getting this is not a very big problem in Delhi in the mentioned area.

I feel you even need not purchase this sheet. You can contact a company in the line and go there and talk to them, they will give you free of cost also.

In our company, we use a lot of aluminium. The students from Engineering college come to our organisation and work on their project in our factory for 3 or 4 months and make their project report. I think it will be possible for you also to proceed in that way. They are many mechanical industries in Delhi and it will be easy for you to come in to contact with a company and you can complete your project thereby utilising the facilities they have.
