5456 Aluminum

Verifiedmetal

5456 is a non-heat-treatable aluminum-magnesium alloy (3-5% Mg) offering excellent seawater and marine corrosion resistance with moderate strength, commonly used in marine structures, shipbuilding, and welded pressure vessels. Available tempers range from fully annealed (O) to various strain-hardened conditions (H111, H112, H321, H34, H38) providing yield strengths from ~95 MPa to ~215 MPa respectively.

Safety & Biocompatibility

Quality & Standards

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.
