What is 413-F?
413-F is 413 in the F temper — standard supply condition for 413/A413 die castings — no thermal treatment; use for as-cast structural and housing parts. 413-F has a yield strength of 145 MPa (21 ksi) and a tensile strength of 300 MPa (43.5 ksi) — weaker than 68% of aluminum grades. Elongation at break is 2.5% and the elastic modulus is 71 GPa (10.3 Msi). 413-F has a density of 2.66 g/cm³ (0.0961 lb/in³), lighter than 84% of aluminum grades. It melts at 574°C (1,065 °F).

Working with 413-F
Is 413 easy to machine?
Machines to good finish with PCD or diamond-coated carbide at high speed and generous coolant; the 12% Si eutectic is abrasive, so expect 2–5× the tool wear of 6061.
Can 413 be welded?
TIG/MIG possible with 4047/4043 filler but entrapped die-cast gas causes porosity and blistering; prefer mechanical joining or adhesive, and pressure-test welded assemblies.
Can 413 be formed, bent or molded?
High-pressure die casting alloy with the best fluidity in the Al family — supports 1–2 mm walls and long flow paths; keep uniform wall thickness, generous fillets and vacuum/venting for pressure-tight parts; not heat treatable.
What surface finishes work on 413?
Anodizing gives a dark grey, patchy film — specify chromate/trivalent conversion, e-coat, powder coat or plating instead; shot blast or vibratory finish removes flash lines before painting.

413-F — frequently asked
What is 413-F used for?
413-F is typically used for pressure-tight die castings, pump housings, gearbox and transmission housings, electric motor end covers, heat sinks and cooled enclosures and electrical and electronic housings. In short: eutectic Al-Si cast.
What is the yield strength of 413-F?
413-F has a typical yield strength of 145 MPa (21 ksi) and a tensile strength of 300 MPa (43.5 ksi) — weaker than 68% of aluminum grades.
Is 413-F easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 65% of aluminum grades). Machines to good finish with PCD or diamond-coated carbide at high speed and generous coolant; the 12% Si eutectic is abrasive, so expect 2–5× the tool wear of 6061.
Can 413-F be welded?
With care — weldability is rated fair (40/100). TIG/MIG possible with 4047/4043 filler but entrapped die-cast gas causes porosity and blistering; prefer mechanical joining or adhesive, and pressure-test welded assemblies.
What surface finishes work on 413-F?
Anodizing gives a dark grey, patchy film — specify chromate/trivalent conversion, e-coat, powder coat or plating instead; shot blast or vibratory finish removes flash lines before painting.
Can 413-F be formed, bent or molded?
High-pressure die casting alloy with the best fluidity in the Al family — supports 1–2 mm walls and long flow paths; keep uniform wall thickness, generous fillets and vacuum/venting for pressure-tight parts; not heat treatable.
What is the maximum service temperature of 413-F?
413-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.
