A unique combination of properties puts aluminium and its alloys among our most versatile engineering andconstruction materials. All alloys are light in weight, yet some have strengths greater than that of structural steel.The majority of alloys are highly durable under most service conditions No coloured salts are formed to stainadjacent surfaces or discolour products with which they come in contact, such as fabrics in the textile industryand solutions in chemical equipment. They have no toxic reaction. Aluminium and most of its alloys have goodelectrical and thermal conductivities and high re ectivity to both heat and light.
