What is 364.0-F?
364.0-F is 364.0 in the F temper — standard supply condition for all 364.0 die castings; use unless a high-integrity vacuum/squeeze-cast part is being heat treated. 364.0-F has a yield strength of 159 MPa (23.1 ksi) and a tensile strength of 296 MPa (42.9 ksi) — weaker than 62% of aluminum grades. Elongation at break is 7.5% and the elastic modulus is 71 GPa (10.3 Msi). 364.0-F has a density of 2.63 g/cm³ (0.095 lb/in³), lighter than 95% of aluminum grades. It melts at 557°C (1,035 °F).
Limitations
- Poor heat conductor — 105 W/m·K (60.7 BTU/hr·ft·°F), worse than 91% of aluminum grades
- Low electrical conductivity — 27 % IACS, worse than 86% of aluminum grades
- Low fracture toughness — 17 MPa·√m (15.5 ksi·√in), worse than 83% of aluminum grades

Working with 364.0-F
Is 364.0 easy to machine?
Machines well with sharp polished-flute carbide (PCD for volume) and high speeds; the eutectic silicon is abrasive, so expect tool wear and avoid cutting into subsurface porosity on sealing faces.
Can 364.0 be welded?
Fusion welding of die castings is unreliable because entrapped gas blows the weld pool — use mechanical fastening, adhesive or self-piercing rivets; TIG repair only on vacuum/low-porosity castings.
Can 364.0 be formed, bent or molded?
Excellent high-pressure die-casting alloy: high fluidity for thin walls, good pressure tightness and low hot-tearing; keep dies hot and gates well fed, and avoid solution heat treatment of gas-porous castings to prevent blistering.
What surface finishes work on 364.0?
Best finished with chromate/Ti-Zr conversion coating plus powder coat or paint; hardcoat anodize is possible but yields a dark grey non-decorative film, and shot blasting or vibratory finishing evens out the as-cast skin.
364.0 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

364.0-F — frequently asked
What is 364.0-F used for?
364.0-F is typically used for thin-wall housings, automotive brackets and electronic enclosures. In short: ductile thin-wall die casting; tight composition control; good pressure tightness.
What is the yield strength of 364.0-F?
364.0-F has a typical yield strength of 159 MPa (23.1 ksi) and a tensile strength of 296 MPa (42.9 ksi) — weaker than 62% of aluminum grades. Strength varies by condition: see the 2 listed tempers.
Is 364.0-F easy to machine?
Reasonably — machinability is rated good (58/100, worse than 54% of aluminum grades). Machines well with sharp polished-flute carbide (PCD for volume) and high speeds; the eutectic silicon is abrasive, so expect tool wear and avoid cutting into subsurface porosity on sealing faces.
Can 364.0-F be welded?
Not readily — weldability is rated poor (30/100). Fusion welding of die castings is unreliable because entrapped gas blows the weld pool — use mechanical fastening, adhesive or self-piercing rivets; TIG repair only on vacuum/low-porosity castings.
What surface finishes work on 364.0-F?
Best finished with chromate/Ti-Zr conversion coating plus powder coat or paint; hardcoat anodize is possible but yields a dark grey non-decorative film, and shot blasting or vibratory finishing evens out the as-cast skin.
Can 364.0-F be formed, bent or molded?
Excellent high-pressure die-casting alloy: high fluidity for thin walls, good pressure tightness and low hot-tearing; keep dies hot and gates well fed, and avoid solution heat treatment of gas-porous castings to prevent blistering.
What is the maximum service temperature of 364.0-F?
364.0-F is rated for continuous use to about 150°C (302 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 364.0-F and 364.0-T5?
F is the default condition — standard supply condition for all 364.0 die castings; use unless a high-integrity vacuum/squeeze-cast part is being heat treated. T5: pick when dimensional stability after machining or a modest strength/hardness gain is needed without the blistering risk of solution treatment. Yield strength is 159 MPa in F versus 200 MPa in T5.
