Extrusion

An amazing metal, aluminum is one-third the weight of steel, won't burn, is not magnetic, has a high inherent resistance to corrosion, and gets stronger as it gets colder. Of the common metals, on a weight basis, aluminum is the most efficient thermal conductor. High purity aluminum is soft and ductile. Its strength and hardness are acquired by the addition of alloying elements like silicon, magnesium, manganese and copper.

Representing about 20% of total aluminum consumption in Pakistan, aluminum extrusions respond readily to bending, stamping, cutting and punching. Extrusions are desirable because they are strong,  resilient, heat and electrically conductive, nontoxic, reflective, no sparking and nonmagnetic.
