5251 Aluminium Alloy Overview

5251 aluminium belongs to high magnesium alloy with 1.7-2.4% Mg content. So, aluminum 5251 alloy shows excellent corrosion resistance, especially in marine atmospheres. Besides, 5251 aluminium also is known for work hardening rapidly, and it’s readily weldable, whether using GTAW (TIG) or GMAW (MIG) method. Similarly, its ductility, formability, workability, fatigue strength are good. Thus making 5251 aluminium sheet coil more widely used in boat, marine structures, vehicle, containers, etc
