Working with 5383-H32
Is 5383 easy to machine?
Gummy, long stringy chips — use sharp polished high-rake carbide, high speed, generous flood or MQL lubricant; expect built-up edge if speeds are low.
Can 5383 be welded?
Excellent for MIG/TIG (ER5183 preferred, ER5356 acceptable) and FSW; HAZ softens to near-O strength, so design joints to annealed-temper allowables and keep interpass temperature low.
Can 5383 be formed, bent or molded?
Good cold formability in O/H111; H116/H321 plate needs generous bend radii (≈2–3 t) and transverse bending is preferred over longitudinal.
What surface finishes work on 5383?
Takes protective clear/hard anodizing and marine epoxy primers well; decorative bright anodize is only fair, and chromate-free conversion coatings are standard for painted hull structures.

5383-H32 has a typical yield strength of 215 MPa (31.2 ksi) and a tensile strength of 325 MPa (47.1 ksi) — stronger than 58% of aluminum grades. Strength varies by condition: see the 9 listed tempers.
Is 5383-H32 easy to machine?
Not especially — machinability is rated fair (44/100, worse than 76% of aluminum grades). Gummy, long stringy chips — use sharp polished high-rake carbide, high speed, generous flood or MQL lubricant; expect built-up edge if speeds are low.
Can 5383-H32 be welded?
Yes — weldability is rated excellent (88/100). Excellent for MIG/TIG (ER5183 preferred, ER5356 acceptable) and FSW; HAZ softens to near-O strength, so design joints to annealed-temper allowables and keep interpass temperature low.
What surface finishes work on 5383-H32?

Can 5383-H32 be formed, bent or molded?
Good cold formability in O/H111; H116/H321 plate needs generous bend radii (≈2–3 t) and transverse bending is preferred over longitudinal.
What is the maximum service temperature of 5383-H32?
5383-H32 is rated for continuous use to about 65°C (149 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
Can FabDigit make parts in 5383-H32?
Yes — 5383-H32 is available for CNC machining and sheet metal; every part is priced by an engineer rather than instantly. Upload a STEP file to get a price and a DFM check.
