Working with 5088-H36
Is 5088 easy to machine?
Machines like other high-Mg 5000 series: gummy in O/H111, better in H34/H38 — use sharp polished high-rake carbide, high speed, generous coolant/lubricant to prevent built-up edge.
Can 5088 be welded?
Excellent GMAW/GTAW and friction-stir weldability with 5183 or 5356 filler; keep interpass temperature low and avoid long exposure at 70–200 °C to prevent β-phase sensitization.
Can 5088 be formed, bent or molded?
Best formed in O/H111; H116/H321 plate takes moderate bends (allow generous inside radius across the rolling direction); watch for Lüders/stretcher-strain marks on annealed sheet.
What surface finishes work on 5088?
Responds well to sulfuric-acid clear and hard anodizing (slightly grey tone from Mg), chemical conversion coating and marine paint systems; polishes to a satin rather than mirror finish.

5088-H36 — frequently asked
What is 5088-H36 used for?
5088-H36 is typically used for marine structural components, automotive structural sheet, welded hull and deck plate, vehicle body reinforcements, offshore walkways and platforms and storage tank shells. In short: high-strength marine 5000 series; stronger than typical 5083; formability traded for strength.
What is the yield strength of 5088-H36?
5088-H36 has a typical yield strength of 310 MPa (45 ksi) and a tensile strength of 385 MPa (55.8 ksi) — stronger than 78% of aluminum grades. Strength varies by condition: see the 11 listed tempers.
Is 5088-H36 easy to machine?
Reasonably — machinability is rated fair (52/100, worse than 63% of aluminum grades). Machines like other high-Mg 5000 series: gummy in O/H111, better in H34/H38 — use sharp polished high-rake carbide, high speed, generous coolant/lubricant to prevent built-up edge.
Can 5088-H36 be welded?
Yes — weldability is rated very good (82/100). Excellent GMAW/GTAW and friction-stir weldability with 5183 or 5356 filler; keep interpass temperature low and avoid long exposure at 70–200 °C to prevent β-phase sensitization.
What surface finishes work on 5088-H36?
Responds well to sulfuric-acid clear and hard anodizing (slightly grey tone from Mg), chemical conversion coating and marine paint systems; polishes to a satin rather than mirror finish.
Can 5088-H36 be formed, bent or molded?
Best formed in O/H111; H116/H321 plate takes moderate bends (allow generous inside radius across the rolling direction); watch for Lüders/stretcher-strain marks on annealed sheet.
What is the maximum service temperature of 5088-H36?
5088-H36 is rated for continuous use to about 65°C (149 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 5088-H116 and 5088-O?
H116 is the default condition — default marine plate condition: high strength plus qualified exfoliation resistance (ASTM G66/G67) for hull and offshore structures. O: pick for maximum formability — deep drawing, tight bending, spinning before any welding or forming-heavy fabrication. Yield strength is 240 MPa in H116 versus 145 MPa in O.
