Divine Metal & Alloy Aluminium alloy 3105 is essentially a 98% aluminium alloy with minor additions to increase strength over that of alloy 1100 and 3003. It is not hardenable by heat treatment and it has good corrosion resistance, formability and weldability. Typical applications include general sheet metal work requiring greater strength than is provided by 1000 series aluminium alloys, residential siding, mobile homes and sign making. 3105 aluminium sheet with 98% pure aluminium and slight alloy additions for strength. 0.3% of copper is added to 3105 aluminium sheet, so the conductivity turns out to be 41%. For its contents and processing technologies, 3105 aluminium sheet is light in weight and it has a semi-smooth surface. Besides, it is not hardened by heat treatment. Mg, Mn and Si are added to 3105 aluminium sheet, thus, it has excellent correction resistance, formability and welding characteristics. Besides, it has average machinability and it can be increased in harder tempers than in annealed condition. Oil lubricants should be used for all machining operations. The forming characteristics of 3105 aluminium sheet are pretty good by all conventional processes regardless of temper. But 3105 aluminium sheet does not respond to heat treatment except for annealing during cold working. The cold working characteristics are very good, even in the harder cold working tempers. For all the features above, 3105 aluminium sheet has a vast of applications in many fields.
