Introduction
3105 aluminum sheet/coil with 98% pure aluminum and slight alloy additions for strength. 0.3% of copper is added to 3105 aluminum sheet/coil, so the conductivity turns out to be 41%. For its contents and processing technologies, 3105 aluminum sheet/coil is light in weight and it has semi-smooth surface. Besides, it is not hardened by heat treatment. All the products live up to international standards, such as ASTM, EN, JIS, etc. Therefore, quality of 3105 aluminum sheet/coil can also be guaranteed. Zhongxin can supply particular specifications at customers’ need besides the following.

Mg, Mn and Si are added to 3105 aluminum 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 aluminum sheet/coil are pretty good by all conventional processes regardless of temper. But 3105 aluminum sheet/coil 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 aluminum sheet/coil has a vast application in many field.
