DIN 1725-1 Grade 3.3354 H14: High-Strength Magnesium Alloy with Excellent Corrosion Resistance

The alloy is 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. AlMg5 has the highest Mg content of the standardized AlMg alloys, so it is badly cold formable, but the strength is the highest, so that the employment is possible for statically more highly loaded constructions. The alloy is suitable for a splinter-giving machinig on automats. It possesses sensitivity to intergranular corrosion. By a purposeful heat treatment and/or by additive of Mn or Cr the inclination to the intergranular corrosion can be reduced. Application: In the optics, in the automobile engineering for body parts, in mechanical engineering (turned parts). For joining elements (solid rivets, blind rivets, riveting nuts and screws). In the building industry for carrying constructions as well as in shipbuilding considering the sensitivity to corrosion.
