Working with 5754-H24
Is 5754 easy to machine?
Machines like soft 5xxx: use sharp polished-flute carbide, high rake, high speed and flood coolant or mist to stop built-up edge; harder H24–H38 tempers chip much cleaner than O.
Can 5754 be welded?
Excellent for MIG/TIG, FSW, resistance and laser welding with 5356 or 5183 filler (never 4043-type Al-Si with high-Mg base); as-welded joint strength approaches O-temper base metal.
Can 5754 be formed, bent or molded?
Very good cold formability in O/H111 (deep drawing, hemming, stretch forming); keep bend radii larger and expect springback in H24 and above, and watch for Lüders/stretcher-strain marks on visible O-temper panels.
What surface finishes work on 5754?
Takes clear and hard anodizing well and is a good base for chemical conversion, e-coat and paint; brushed/etched finishes are excellent, bright decorative anodizing can appear slightly grey.

What is 5754-H24 used for?
5754-H24 is typically used for automotive inner body panels, floor and tread plate, marine and vehicle sheet panels, welded pressure vessel shells, truck and trailer body panels and riveted sheet-metal enclosures. In short: auto body / structural sheet.
What is the yield strength of 5754-H24?
5754-H24 has a typical yield strength of 180 MPa (26.1 ksi) and a tensile strength of 260 MPa (37.7 ksi) — weaker than 54% of aluminum grades. Strength varies by condition: see the 16 listed tempers.
Is 5754-H24 easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 65% of aluminum grades). Machines like soft 5xxx: use sharp polished-flute carbide, high rake, high speed and flood coolant or mist to stop built-up edge; harder H24–H38 tempers chip much cleaner than O.
Can 5754-H24 be welded?
Yes — weldability is rated excellent (92/100). Excellent for MIG/TIG, FSW, resistance and laser welding with 5356 or 5183 filler (never 4043-type Al-Si with high-Mg base); as-welded joint strength approaches O-temper base metal.
