Working with EN AC-41000-F
Is EN AC-41000 easy to machine?
Machines like a soft wrought 6000-series alloy — sharp polished-flute carbide tools, high speed, generous coolant to avoid built-up edge and gummy chips.
Can EN AC-41000 be welded?
Very good TIG/MIG weldability with 4043 or 5356 filler; re-solution + age locally welded structural parts to restore T6 strength.
Can EN AC-41000 be formed, bent or molded?
Poor fluidity and high hot-tearing tendency — use thick sections, generous fillets, strong feeders and controlled mould temperature; not suited to high-pressure die casting.
What surface finishes work on EN AC-41000?
Outstanding decorative and hard anodizing (clear, even colour) because of the low Si; also takes chemical conversion coating, polishing and powder paint well.

EN AC-41000-F — frequently asked
What is EN AC-41000-F used for?
EN AC-41000-F is typically used for electrical fittings, conductor components and lightly loaded castings. In short: best-anodizing cast aluminium; weldable cast alloy; low fluidity.
What is the yield strength of EN AC-41000-F?
EN AC-41000-F has a typical yield strength of 75 MPa (10.9 ksi) and a tensile strength of 145 MPa (21 ksi) — weaker than 91% of aluminum grades. Strength varies by condition: see the 3 listed tempers.
Is EN AC-41000-F easy to machine?
Reasonably — machinability is rated good (62/100, better than 55% of aluminum grades). Machines like a soft wrought 6000-series alloy — sharp polished-flute carbide tools, high speed, generous coolant to avoid built-up edge and gummy chips.
Can EN AC-41000-F be welded?
Yes — weldability is rated very good (72/100). Very good TIG/MIG weldability with 4043 or 5356 filler; re-solution + age locally welded structural parts to restore T6 strength.
What surface finishes work on EN AC-41000-F?
Outstanding decorative and hard anodizing (clear, even colour) because of the low Si; also takes chemical conversion coating, polishing and powder paint well.
Can EN AC-41000-F be formed, bent or molded?
Poor fluidity and high hot-tearing tendency — use thick sections, generous fillets, strong feeders and controlled mould temperature; not suited to high-pressure die casting.
What is the maximum service temperature of EN AC-41000-F?
EN AC-41000-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 EN AC-41000-T6 and EN AC-41000 T6-K?
T6 is the default condition — standard supply condition: best balance of strength, ductility and anodizing quality for sand-cast conductive or decorative parts. T6-K: choose when the part is gravity die (permanent-mould) cast — finer structure raises strength and elongation well above sand-cast T6. Yield strength is 130 MPa in T6 versus 195 MPa in T6-K.
