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

3105-H14 aluminum is 3105 aluminum in the H14 temper. To achieve this temper, the metal is strain hardened to a strength that is roughly halfway between annealed (O) and full-hard (H18). The graph bars on the material properties cards below compare 3105-H14 aluminum to: 3000-series alloys (top), all aluminum alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it’s 50% of the highest, and so on.

Application of 3105 alloy aluminium plate roll

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