What is 5049?
5049 (A95049, EN AW-5049, 3.3527, AlMg2Mn0.8) is a medium-strength, manganese-modified Al-Mg sheet and plate alloy, non-heat-treatable and strengthened by cold work. It serves as a general engineering and marine fabrication grade, with weldability 88 and corrosion resistance 78, and is available in O, H111/H112 and a wide range of H1x, H2x and H3x tempers. Default values are 150 MPa yield, 240 MPa tensile, 11% elongation and 62 HB. Welded joints fall to about 190 MPa in the HAZ with no post-weld heat treatment available, and brazing is not recommended; 5052 is the nearest widely stocked alternative. 5049 has a density of 2.69 g/cm³ (0.0972 lb/in³), lighter than 67% of aluminum grades. It melts at 610°C (1,130 °F). 5049 has a yield strength of 150 MPa (21.8 ksi) and a tensile strength of 240 MPa (34.8 ksi) — weaker than 65% of aluminum grades. Elongation at break is 11% and the elastic modulus is 70 GPa (10.2 Msi).

Working with 5049
Is 5049 easy to machine?
Gummy in O/H1xx tempers — use sharp polished high-rake carbide, high speed, generous flood or MQL lubrication; harder H16–H38 tempers chip and finish better.
Can 5049 be welded?
Readily GMAW/GTAW welded with ER5356 or ER5183 filler; weld joint reverts to about O-temper strength (~190 MPa) in the HAZ, no post-weld heat treatment possible.
Can 5049 be formed, bent or molded?
Excellent cold formability in O/H111/H22; allow larger bend radii and consider grain-direction effects above H16, and avoid stretcher strain (Lüders) lines by using stabilized H2x/H3x tempers.

What surface finishes work on 5049?
Takes clear and hard anodizing well (slightly grey tone), plus chromate/chrome-free conversion coating, powder coat and paint; brazing is not recommended due to the Mg content.

5049 — frequently asked
What is 5049 used for?
5049 is typically used for marine fittings, general sheet metal fabrication and welded structures. In short: weldable marine sheet grade; mn-modified 5000-series workhorse; broad temper availability.
What is the yield strength of 5049?
5049 has a typical yield strength of 150 MPa (21.8 ksi) and a tensile strength of 240 MPa (34.8 ksi) — weaker than 65% of aluminum grades. Strength varies by condition: see the 19 listed tempers.
Is 5049 easy to machine?
Reasonably — machinability is rated fair (45/100, worse than 72% of aluminum grades). Gummy in O/H1xx tempers — use sharp polished high-rake carbide, high speed, generous flood or MQL lubrication; harder H16–H38 tempers chip and finish better.
Can 5049 be welded?
Yes — weldability is rated excellent (88/100). Readily GMAW/GTAW welded with ER5356 or ER5183 filler; weld joint reverts to about O-temper strength (~190 MPa) in the HAZ, no post-weld heat treatment possible.

What is the maximum service temperature of 5049?
5049 is rated for continuous use to about 120°C (248 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.

H22 is the default condition — most commonly stocked 5049 sheet/coil: quarter-hard strength with stabilized ductility for forming and welding. H18: maximum cold-worked strength; use only for flat or lightly formed parts. Yield strength is 150 MPa in H22 versus 268 MPa in H18.
