Working with 5154-H111
Is 5154 easy to machine?
Machines like other 5xxx alloys: gummy and prone to built-up edge — use sharp polished high-rake tools, high speeds and flood lubricant; harder H34–H38 tempers give cleaner chips than O.
Can 5154 be welded?
Readily GTAW/GMAW welded with 5356 or 5183 filler; weld metal keeps near-O strength so joints are designed on annealed properties, and 5183/5356 filler avoids the hot cracking seen with 4043 on high-Mg alloys.
Can 5154 be formed, bent or molded?
Excellent cold formability in O/H111; H32 handles moderate bending while H36/H38 need generous bend radii or intermediate annealing at 340–410 °C.
What surface finishes work on 5154?
Takes sulfuric clear and hard anodize well and accepts chromate/no-chrome conversion coats and marine paint systems; mechanical polishing is fair, bright decorative anodize can show a slight grey tone from the high Mg.

5154-H111 is typically used for welded structural sheet and plate assemblies, storage tanks, pressure vessel shells, marine hull and deck plate, road tanker barrels and chemical process tanks. In short: stronger 5052 alternative.
What is the yield strength of 5154-H111?
5154-H111 has a typical yield strength of 130 MPa (18.9 ksi) and a tensile strength of 245 MPa (35.5 ksi) — weaker than 74% of aluminum grades. Strength varies by condition: see the 15 listed tempers.
Is 5154-H111 easy to machine?
Not especially — machinability is rated fair (38/100, worse than 83% of aluminum grades). Machines like other 5xxx alloys: gummy and prone to built-up edge — use sharp polished high-rake tools, high speeds and flood lubricant; harder H34–H38 tempers give cleaner chips than O.
Can 5154-H111 be welded?
Yes — weldability is rated excellent (88/100). Readily GTAW/GMAW welded with 5356 or 5183 filler; weld metal keeps near-O strength so joints are designed on annealed properties, and 5183/5356 filler avoids the hot cracking seen with 4043 on high-Mg alloys.
