High strength with safety margin: ALUSTAR® (AA5059) offers higher yield strength compared with common AA5083 grades, supporting robust designs.
Marine‑grade corrosion resistance: Proven performance in marine environments and compatibility with industry welding practices.
Efficiency in build and design: Wide thickness/current windows for pulsed MIG welding support consistent fusion and productivity across plate gauges.
Representative properties (typical values):
AA5059 H111 (12.5–40 mm): Rm ≈ 333 MPa; Rp0.2 ≈ 175 MPa; A ≈ 25%
AA5059 H321 (4–<12.5 mm): Rm ≈ 380 MPa; Rp0.2 ≈ 320 MPa; A ≈ 12%
Welding parameters (pulsed MIG welding): AA5183 filler; Argon or Argon/Helium shielding; weld speeds approx. 0.6–1.3 m/min depending on thickness and gas mix. (Use as guidance; confirm per classification.)
