What is 213.0-F?
213.0-F is 213.0 in the F temper — standard supply condition: no heat treatment, permanent-mold castings machined directly. 213.0-F has a yield strength of 105 MPa (15.2 ksi) and a tensile strength of 165 MPa (23.9 ksi) — weaker than 84% of aluminum grades. Elongation at break is 1.5% and the elastic modulus is 73 GPa (10.6 Msi). 213.0-F has a density of 2.95 g/cm³ (0.107 lb/in³), heavier than 99% of aluminum grades. It melts at 545°C (1,013 °F).

Working with 213.0-F
Is 213.0 easy to machine?
Free machining with sharp carbide or PCD tools, high speed and light feed; the Cu/Zn content gives short chips and good finish with soluble-oil coolant.
Can 213.0 be welded?
Not recommended for structural welds — high Cu makes it hot-crack sensitive; repair with 4145/4043 filler only for cosmetic defects, or use mechanical joining.
Can 213.0 be formed, bent or molded?
Sand and permanent-mold casting only; needs generous risers and controlled solidification because of wide freezing range and shrinkage/hot-tear tendency; not heat treated in service (F temper).
What surface finishes work on 213.0?
Do not rely on anodizing (dark, patchy film); use chromate/phosphate conversion plus primer and paint, or nickel/zinc-based plating over a suitable strike, for corrosion protection.

213.0-F — frequently asked
What is 213.0-F used for?
213.0-F is typically used for general machinery castings, housings and hardware. In short: free-machining cast Al-Cu-Si; as-cast F temper only; low ductility, legacy grade.
What is the yield strength of 213.0-F?
213.0-F has a typical yield strength of 105 MPa (15.2 ksi) and a tensile strength of 165 MPa (23.9 ksi) — weaker than 84% of aluminum grades. Strength varies by condition: see the 2 listed tempers.
Is 213.0-F easy to machine?
Yes — machinability is rated very good (82/100, better than 94% of aluminum grades). Free machining with sharp carbide or PCD tools, high speed and light feed; the Cu/Zn content gives short chips and good finish with soluble-oil coolant.
Can 213.0-F be welded?
Not readily — weldability is rated poor (25/100). Not recommended for structural welds — high Cu makes it hot-crack sensitive; repair with 4145/4043 filler only for cosmetic defects, or use mechanical joining.
What surface finishes work on 213.0-F?
Do not rely on anodizing (dark, patchy film); use chromate/phosphate conversion plus primer and paint, or nickel/zinc-based plating over a suitable strike, for corrosion protection.
Can 213.0-F be formed, bent or molded?
Sand and permanent-mold casting only; needs generous risers and controlled solidification because of wide freezing range and shrinkage/hot-tear tendency; not heat treated in service (F temper).
What is the maximum service temperature of 213.0-F?
213.0-F is rated for continuous use to about 175°C (347 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between 213.0-F and 213.0 F-SAND?
F is the default condition — standard supply condition: no heat treatment, permanent-mold castings machined directly. F-SAND: choose for larger or low-volume sand castings; slightly lower ductility and more scatter than permanent mold. Yield strength is 105 MPa in F versus 110 MPa in F-SAND.
