1050 aluminium   is an aluminium-based  in the "commercially pure" wrought family (1000 or 1xxx series).   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. 

Owing to the good  conductivity  and good price,1050 aluminium foils are widely used  for  dry type transformer  windings in recent years.
