Working with 5954-H111
Is 5954 easy to machine?
Gummy like all 5000 series — use sharp polished high-rake carbide, high surface speed, flood coolant or MQL and generous chip room to avoid built-up edge; harder H3x tempers cut cleaner than O.
Can 5954 be welded?
Excellent for GMAW/GTAW and FSW with ER5356 or ER5183 filler; HAZ softens to about O-temper strength, so design welds to annealed allowables and avoid Mg-loss from excessive heat input.
Can 5954 be formed, bent or molded?
Very good cold formability in O/H111/H32; watch Lüders (stretcher-strain) marks in O temper, allow generous bend radii in H34 and above, and inter-anneal at 340–400 °C for deep draws.
What surface finishes work on 5954?
Anodises well (clear/hardcoat) with a slightly grey tone; also takes conversion coating, powder coat and marine paint systems — avoid strong alkaline cleaners which etch high-Mg aluminium rapidly.

What is 5954-H111 used for?
5954-H111 is typically used for industrial sheet and plate, tank cars, welded storage tanks, pressure vessel shells, ship structural panels and vehicle body panels. In short: high-Mg specialty plate.
What is the yield strength of 5954-H111?
5954-H111 has a typical yield strength of 125 MPa (18.1 ksi) and a tensile strength of 245 MPa (35.5 ksi) — weaker than 75% of aluminum grades. Strength varies by condition: see the 17 listed tempers.
Is 5954-H111 easy to machine?
Not especially — machinability is rated poor (30/100, worse than 92% of aluminum grades). Gummy like all 5000 series — use sharp polished high-rake carbide, high surface speed, flood coolant or MQL and generous chip room to avoid built-up edge; harder H3x tempers cut cleaner than O.
Can 5954-H111 be welded?
Yes — weldability is rated excellent (88/100). Excellent for GMAW/GTAW and FSW with ER5356 or ER5183 filler; HAZ softens to about O-temper strength, so design welds to annealed allowables and avoid Mg-loss from excessive heat input.
What surface finishes work on 5954-H111?
Anodises well (clear/hardcoat) with a slightly grey tone; also takes conversion coating, powder coat and marine paint systems — avoid strong alkaline cleaners which etch high-Mg aluminium rapidly.
Can 5954-H111 be formed, bent or molded?
Very good cold formability in O/H111/H32; watch Lüders (stretcher-strain) marks in O temper, allow generous bend radii in H34 and above, and inter-anneal at 340–400 °C for deep draws.
What is the maximum service temperature of 5954-H111?
5954-H111 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.
Can FabDigit make parts in 5954-H111?
Yes — 5954-H111 is available for CNC machining and sheet metal; every part is priced by an engineer rather than instantly. Upload a STEP file to get a price and a DFM check.
