What is 5025?
5025 is a registered wrought Al–Mg (5000 series) alloy with roughly 1 % magnesium plus a small manganese addition, supplied almost exclusively as sheet, strip and coil in the annealed (O) and strain-hardened/stabilised H2x–H3x tempers. It is chosen for the classic 5000-series combination of good cold formability, good weldability, excellent marine/atmospheric corrosion resistance and a clean anodised finish at moderate strength. Limits are low absolute strength versus heat-treatable 6000/7000 series alloys, work-softening above roughly 100–150 °C, and poor machinability (gummy chips) compared with free-machining alloys; registered mechanical data for this specific number are sparse, so values below are typical 5000-series-class figures and should be confirmed against the supplier's certificate. 5025 has a density of 2.69 g/cm³ (0.0972 lb/in³), lighter than 67% of aluminum grades. It melts at 620°C (1,148 °F). 5025 has a yield strength of 155 MPa (22.5 ksi) and a tensile strength of 195 MPa (28.3 ksi) — weaker than 63% of aluminum grades. Elongation at break is 10% and the elastic modulus is 69.5 GPa (10.1 Msi).

Working with 5025
Is 5025 easy to machine?
Soft and gummy — use polished high-rake carbide, high surface speed, generous flood or MQL lubrication and chip-breaking geometry to avoid built-up edge.
Can 5025 be welded?
Readily GTAW/GMAW welded with 5356 (or 5183/5556 for higher strength) filler; the weld reverts to near-O properties, so design joints on annealed strength.
Can 5025 be formed, bent or molded?
Excellent cold formability in O/H22/H32; allow for springback in H3x tempers and inter-anneal at 340–380 °C for severe multi-stage draws.

What surface finishes work on 5025?
Anodises bright and uniformly, takes conversion coating and paint well; poor for brazing and only fair for soldering because of the magnesium oxide film.
