Description

The alloy AlMg4,5Mn belongs to the nature-hard aluminum wrought materials, so a strength increase can be achieved only by cold forming, not by a purposeful heat treatment. The material is characterised by good corrosion resistance. It is sea water steady and steady against saline atmosphere. Increasing Mg+Mn content makes the extrusion more difficult, but strength and very low-temperature behaviour improve. The alloy is well weldable. Even in the welding seams strength lie within the range of AlMg5. The alloy AlMg4Mn is standardised as semi-finished material only as sheet metal or strips, thickness: >= 0,35 mm (DIN 1745). Application: rolling shutter and roll gates (sheet metal profiles), in the apparatus engineering for tank bottoms, very low-temperature tanks, heat exchangers and pipings. In the construction of vehicles for superstructures as well as tank and silo trucks, dump truck hollows, buses, bumpers, car body and safety-related parts. In shipbuilding for trunk, superstructures, sail masts and radar equipment

Equivalent Materials

This material data has been provided by WIAM,AluKey.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
