Overview
- Deformable aluminum brand
- The aluminum content of not less than 99,5 %
- It has no special alloying elements. They are present as inevitable impurities
- Full analog aluminum brand AD0 GOST 4784-97
- earlier, basic, aluminum brand 1050 (without the letter A) differs in more stringent requirements for the zinc content (0.05 %) and titanium (0.03 %), as well as a separate control of vanadium (0.05 %) [1]
- Belongs to the series (class) 1xxx according to the international classification of deformable grades of aluminum and aluminum alloys
- The European standards, for example, EN 573, designated EN AW-1050A
- It has a low mechanical strength and moderate
- It has a high plasticity and capability to forming
- Processed by pressing (extrusion) methods, drawing, hot and cold rolling
