5083 Aluminum H343
Verifiedmetal5083 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.

Industry-Specific
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
