Working with EN AC-46500-T5
Is EN AC-46500 easy to machine?
Machines freely with sharp PCD or coated carbide at high speed; primary Si and Fe-rich needles abrade HSS quickly, so use PCD for volume and flood coolant to avoid built-up edge.
Can EN AC-46500 be welded?
Not recommended as a structural joining method for HPDC parts — entrapped gas causes porosity and blowholes; use mechanical fastening, adhesive bonding, or localized TIG/FSW repair on vacuum-cast material.
Can EN AC-46500 be formed, bent or molded?
Designed for cold-chamber high-pressure die casting: excellent fluidity for 1–2 mm walls, low die soldering thanks to Fe content; avoid solution treatment (T6) as gas porosity causes blistering.
What surface finishes work on EN AC-46500?
Best finished by chromate-free conversion coating + powder/wet paint or e-coat; decorative anodizing is poor (dark, patchy) — only functional hard anodize, and shot blasting/vibratory finishing are common.

EN AC-46500-T5 — frequently asked
What is EN AC-46500-T5 used for?
EN AC-46500-T5 is typically used for engine covers, transmission housings and general die castings. In short: cheapest high-volume die casting; highest as-cast strength here; scrap-tolerant secondary alloy.
What is the yield strength of EN AC-46500-T5?
EN AC-46500-T5 has a typical yield strength of 190 MPa (27.6 ksi) and a tensile strength of 310 MPa (45 ksi) — weaker than 52% of aluminum grades. Strength varies by condition: see the 3 listed tempers.
Is EN AC-46500-T5 easy to machine?
Reasonably — machinability is rated good (64/100, better than 58% of aluminum grades). Machines freely with sharp PCD or coated carbide at high speed; primary Si and Fe-rich needles abrade HSS quickly, so use PCD for volume and flood coolant to avoid built-up edge.
Can EN AC-46500-T5 be welded?
Not readily — weldability is rated poor (20/100). Not recommended as a structural joining method for HPDC parts — entrapped gas causes porosity and blowholes; use mechanical fastening, adhesive bonding, or localized TIG/FSW repair on vacuum-cast material.
What surface finishes work on EN AC-46500-T5?
Best finished by chromate-free conversion coating + powder/wet paint or e-coat; decorative anodizing is poor (dark, patchy) — only functional hard anodize, and shot blasting/vibratory finishing are common.
Can EN AC-46500-T5 be formed, bent or molded?
Designed for cold-chamber high-pressure die casting: excellent fluidity for 1–2 mm walls, low die soldering thanks to Fe content; avoid solution treatment (T6) as gas porosity causes blistering.
What is the maximum service temperature of EN AC-46500-T5?
EN AC-46500-T5 is rated for continuous use to about 170°C (338 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between EN AC-46500-F and EN AC-46500 F-GDC?
F is the default condition — standard supply condition for essentially all EN AC-46500 parts: as-cast HPDC, no heat treatment. F-GDC: occasional low-volume route (sand or gravity die); slower solidification coarsens the structure so strength and ductility fall below HPDC values. Yield strength is 160 MPa in F versus 120 MPa in F-GDC.
