The aluminium grade in modern windows is typically Alloy 6063, offering all the machining, corrosion-resistance, heat treatments for colouring and other characteristics suitable for the windows and doors we buy for our homes, factories and commercial buildings – otherwise known as ‘Architectural Applications.’

In most instances, the billets are cast in an electric arc furnace with aluminum scraps. They are cut into ideal sizes to match the required profile length.

Wrought iron is generally longer-lasting than cast iron. As we said, cast iron is harder but it’s also more brittle. The extra carbon in its molecular structure compared with wrought iron results in internal stress points that are more likely to fracture under extreme stress rather than bend. There are advantages and disadvantages to this: cast iron is more likely to retain its exact shape without undergoing any warping or bending.
