Why Choose Aluminum for transformer?
Economic ,means less cost for better achievements
Conductivity of Copper is better,but Aluminum's is as double as copper at the same price.
Aluminum is more flexible that means it easier to wind and place in winding process.
Aluminum is lighter,easy to place.
In North America ,aluminum is the moost popular choice of winding material for low
-voltage,dry-type transformers.

Chemical composition
1050 aluminium alloy
1050 aluminium alloy is an aluminium-based alloy in the "commercially pure" wrought family (1000 or 1xxx series). As a wrought alloy, it is not used in castings. Instead, it is usually formed by extrusion or rolling. It is commonly used in the electrical and chemical industries, on account of having high electrical conductivity, corrosion resistance, and workability. 1050 alloy is also sometimes used for the manufacture of heat sinks, since it has a higher thermal conductivity than other alloys. It has low mechanical strength compared to more significantly alloyed metals. It can be strengthened by cold working, but not by heat treatment.
Alternate names and designations include Al99.5, 3.0255, and A91050.
