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 aluminum foil 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.
