Properties of the O condition, compared with the other 5352 tempers.
Pick for deep drawing, severe bending or spinning where maximum ductility matters more than strength.
What is 5352-O?
5352-O is 5352 in the O temper — pick for deep drawing, severe bending or spinning where maximum ductility matters more than strength. 5352-O has a yield strength of 90 MPa (13.1 ksi) and a tensile strength of 195 MPa (28.3 ksi) — weaker than 87% of aluminum grades. Elongation at break is 25% and the elastic modulus is 70.3 GPa (10.2 Msi). 5352-O has a density of 2.68 g/cm³ (0.0968 lb/in³), lighter than 72% of aluminum grades. It melts at 607°C (1,125 °F).

Working with 5352-O
Is 5352 easy to machine?
Soft and gummy — use polished high-rake carbide, high surface speed, generous coolant/lubrication and chip-clearing geometry to avoid built-up edge.
Can 5352 be welded?
Excellent GTAW/GMAW weldability with 5356 or 5183 filler; do not use 4xxx Si filler (brittle Mg2Si) and expect weld-zone strength near the O temper.
Can 5352 be formed, bent or molded?
Very good cold formability in O/H32; anneal at ~340 °C for severe draws and allow for pronounced springback and possible Lüders (stretcher-strain) marks in the annealed state.
What surface finishes work on 5352?
Takes clear and hard anodizing well and polishes to a bright finish; also accepts chemical conversion coating and paint after normal alkaline/acid pretreatment.

5352-O — frequently asked
What is 5352-O used for?
5352-O is typically used for weld filler wire, marine sheet panels, formed sheet enclosures, deep-drawn sheet components, anodized trim and nameplates and tank and vessel sheet. In short: 5xxx weld filler.
What is the yield strength of 5352-O?
5352-O has a typical yield strength of 90 MPa (13.1 ksi) and a tensile strength of 195 MPa (28.3 ksi) — weaker than 87% of aluminum grades. Strength varies by condition: see the 14 listed tempers.
Is 5352-O easy to machine?
Not especially — machinability is rated poor (32/100, worse than 88% of aluminum grades). Soft and gummy — use polished high-rake carbide, high surface speed, generous coolant/lubrication and chip-clearing geometry to avoid built-up edge.
Can 5352-O be welded?
Yes — weldability is rated excellent (90/100). Excellent GTAW/GMAW weldability with 5356 or 5183 filler; do not use 4xxx Si filler (brittle Mg2Si) and expect weld-zone strength near the O temper.
What surface finishes work on 5352-O?
Takes clear and hard anodizing well and polishes to a bright finish; also accepts chemical conversion coating and paint after normal alkaline/acid pretreatment.
Can 5352-O be formed, bent or molded?
Very good cold formability in O/H32; anneal at ~340 °C for severe draws and allow for pronounced springback and possible Lüders (stretcher-strain) marks in the annealed state.
What is the maximum service temperature of 5352-O?
5352-O 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.
