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 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 mechinability 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 application in many field.
A wrought alloy generally comparable to 3003 in properties and characteristics. Typically used for building product applications, it can also be used for other industrial applications.
