| MAXXALLOY®-Structure |
| MAXXALLOY®-Structure is a low-iron aluminium alloy for use in die casting. The long solidifying interval ensures good mould filling. The tendency to warm crack formation is low. Despite the low iron content, the alloy does not tend toward sticking; thanks to the presence of manganese and chromium, even thin-walled parts can be moulded well. When designing the draughts, the higher shrinkage of MAXXALLOY®-Structure during solidification compared to AlSi alloys must be taken into consideration.
Depending on the wall thickness, excellent mechanical properties can be achieved without heat treatment. In particular, the high ductile yield in thin-walled parts should be emphasised. The addition of chromium increases the heat resistance of the cast parts, which sharply reduces distortion during removal from the mould. The alloy is corrosion-resistant and is excellently suited for welding. The preferred application of MAXXALLOY®-Structure is in die cast parts with a wall thickness of 2 - 4mm. The very good weldability permits the manufacture of complex modules from cast parts and, for example, extruded profiles made from 5000 and 6000 series alloys. Examples of these are structural parts. |
