5083 Aluminum H343 is a strain-hardened Al-Mg alloy (approximately 4.4% Mg) widely used in marine and aerospace applications requiring superior corrosion resistance and moderate strength. The H343 temper provides enhanced strength through controlled cold-work followed by stabilization heat treatment, delivering yield strength around 215 MPa with good ductility and excellent seawater corrosion resistance in sheet and plate forms.
