DIN 1725-1 Grade 3.3316 O Aluminium‑Magnesium Alloy – Corrosion‑Resistant & High Strength
The alloys are characterised by a good corrosion resistance. It is sea water steady and resistant to saline atmosphere. The Mg content increases the strength, but the cold forming capacity decreases. The material is nature hard, i.e. only by a cold forming and not by a purposeful heat treatment a strength increase can be attained. It is well polishable and anodisable. The splinter-giving machinability becomes better with increasing Mg content, just as the weldability. From the AlMg alloys the mark AlMg1,5 has to exhibit only relatively small mechanical properties. Standardised semi-finished material only for sheet metal and strips with thickness: > 0.35 mm in accordance to DIN 1745. Application: The main application lies in the building industry. In the building industry for lamella net curtains, rolling shutter, roll gates, in food industry (including table-ware) and for transport containers.
