Working with EN AC-47100-F
Is EN AC-47100 easy to machine?
Machines with short chips but the eutectic/primary Si is abrasive — use PCD or coated carbide, high speed, low feed, flood coolant; watch for porosity breaking through in pressure-tight surfaces.
Can EN AC-47100 be welded?
Not recommended for structural fusion welding of die castings (entrapped gas causes blowholes); if required use TIG/MIG with ER4047 filler on thick, low-porosity sections, or use mechanical joining/adhesives.
Can EN AC-47100 be formed, bent or molded?
Excellent high-pressure die-casting alloy: near-eutectic fluidity fills walls down to ~1 mm, low hot-tearing tendency, long die life; not heat-treatable to higher strength and not cold formable.
What surface finishes work on EN AC-47100?
Best finished with chromate-free conversion coating + powder coat/paint, shot blast or trivalent-chrome plating; decorative anodizing gives a dark grey mottled film due to high Si.

EN AC-47100-F — frequently asked
What is EN AC-47100-F used for?
EN AC-47100-F is typically used for thin-wall die castings, covers and housings. In short: economical thin-wall die casting; fe-tolerant secondary alloy; near-eutectic casting fluidity.
What is the yield strength of EN AC-47100-F?
EN AC-47100-F has a typical yield strength of 140 MPa (20.3 ksi) and a tensile strength of 240 MPa (34.8 ksi) — weaker than 70% of aluminum grades. Strength varies by condition: see the 2 listed tempers.
Is EN AC-47100-F easy to machine?
Reasonably — machinability is rated fair (45/100, worse than 72% of aluminum grades). Machines with short chips but the eutectic/primary Si is abrasive — use PCD or coated carbide, high speed, low feed, flood coolant; watch for porosity breaking through in pressure-tight surfaces.
Can EN AC-47100-F be welded?
Not readily — weldability is rated poor (30/100). Not recommended for structural fusion welding of die castings (entrapped gas causes blowholes); if required use TIG/MIG with ER4047 filler on thick, low-porosity sections, or use mechanical joining/adhesives.
What surface finishes work on EN AC-47100-F?
Best finished with chromate-free conversion coating + powder coat/paint, shot blast or trivalent-chrome plating; decorative anodizing gives a dark grey mottled film due to high Si.
Can EN AC-47100-F be formed, bent or molded?
Excellent high-pressure die-casting alloy: near-eutectic fluidity fills walls down to ~1 mm, low hot-tearing tendency, long die life; not heat-treatable to higher strength and not cold formable.
What is the maximum service temperature of EN AC-47100-F?
EN AC-47100-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-47100-F and EN AC-47100 F-K?
F is the default condition — the only condition registered in EN 1706 for this alloy: as-cast high-pressure die castings, used directly with no heat treatment. F-K: occasionally supplied as gravity/permanent-mould castings of the same chemistry; coarser eutectic gives lower strength than die casting but slightly better ductility and machinability. Yield strength is 140 MPa in F versus 95 MPa in F-K.
