Values for the F condition
What is A380-F?
A380-F is A380 in the F temper — standard supply condition: the alloy is used exactly as it comes out of the die, no heat treatment. A380-F has a yield strength of 159 MPa (23.1 ksi) and a tensile strength of 324 MPa (47 ksi) — weaker than 62% of aluminum grades. Elongation at break is 3.5% and the elastic modulus is 71 GPa (10.3 Msi). A380-F has a density of 2.76 g/cm³ (0.0997 lb/in³), heavier than 70% of aluminum grades. It melts at 540°C (1,004 °F).
Limitations
- Low electrical conductivity — 23 % IACS, worse than 97% of aluminum grades
- Poor heat conductor — 96 W/m·K (55.5 BTU/hr·ft·°F), worse than 95% of aluminum grades
- Limited formability — 10/100, worse than 80% of aluminum grades
- Limited ductility — 3.5%, worse than 76% of aluminum grades
- Difficult to weld — 25/100, worse than 76% of aluminum grades

Corrosion resistance is fair (42/100), worse than 69% of aluminum grades.
Sustainability4
Producing a kilogram of A380-F takes about 195 MJ of energy and emits 11.5 kg of CO₂ — less than 86% of aluminum grades. Typical recycled content is 85%.
Manufacturability7
A380-F's machinability is very good (70/100, better than 72% of aluminum grades); weldability poor (25/100); formability not recommended (10/100).

Working with A380-F
Is A380 easy to machine?
Machines freely with carbide (PCD for long runs) — Si particles are abrasive; use high speed, sharp positive rake and flood coolant, and avoid breaking into subsurface porosity on sealing faces.
Can A380 be welded?
Not recommended for structural fusion welding (Cu content plus die-cast gas porosity cause cracking/blowholes); use mechanical fastening, adhesives or laser/friction-stir with tight process control.
Can A380 be formed, bent or molded?
Excellent high-pressure die-casting alloy: narrow freezing range, good fluidity for 1–2 mm walls, low die soldering; not solution heat treatable because entrapped gas blisters.
What surface finishes work on A380?
Take paint, powder coat, chromate/trivalent conversion and electroless nickel well; anodizing gives dark non-uniform films, so use hard-coat only for wear, not for appearance.

A380-F — frequently asked
What is A380-F used for?
A380-F is typically used for power tool housings, engine and accessory brackets, gearbox and electronics enclosures, thin-wall covers and end caps, automotive under-hood housings and appliance and garden equipment frames. In short: most common die cast.
What is the yield strength of A380-F?
A380-F has a typical yield strength of 159 MPa (23.1 ksi) and a tensile strength of 324 MPa (47 ksi) — weaker than 62% of aluminum grades.
Is A380-F easy to machine?
Yes — machinability is rated very good (70/100, better than 72% of aluminum grades). Machines freely with carbide (PCD for long runs) — Si particles are abrasive; use high speed, sharp positive rake and flood coolant, and avoid breaking into subsurface porosity on sealing faces.
Can A380-F be welded?
Not readily — weldability is rated poor (25/100). Not recommended for structural fusion welding (Cu content plus die-cast gas porosity cause cracking/blowholes); use mechanical fastening, adhesives or laser/friction-stir with tight process control.

What is the maximum service temperature of A380-F?
A380-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.
Can FabDigit make parts in A380-F?
Yes — A380-F is available for CNC machining and casting & forging; every part is priced by an engineer rather than instantly. Upload a STEP file to get a price and a DFM check.
