DIN 1725-1 Grade 3.0915 H1x Aluminum Alloy – High Strength, Excellent Formability & Conductivity

The alloy AlFeSi is alloyed for increasing the strength increase with Fe and Si. The material belongs to the nature-hard aluminum materials. A strength increase can be achieved only by cold forming. The alloy AlFeSi is very well cold and warm formable and has a good thermal and relatively good electrical conductivity. The material is particularly suitable for deep-drawing. It is well solderable. The material is to be oxidized well anodically, i.e. a shining clean surface develops. It is standardised as sheet metal or strip (DIN 1788 and DIN 1745). Application: for screw-type caps, for menu bowls, for light containers, bottle caps, cover containers and other form packing, for metal goods, like trim, decorated tiles, flexible pipes, various deep-drawing products, for heat exchangers and radiator fins
