Working with EN AC-46100-T5
Is EN AC-46100 easy to machine?
Machines freely with PCD or polished-flute carbide at high speed; eutectic Si is abrasive so avoid HSS, and expect porosity to break through on deep pockets and sealing faces.
Can EN AC-46100 be welded?
Not recommended for structural welds — entrapped die-cast gas blisters and Cu promotes hot cracking; use 4047/4145 filler, laser or friction stir only on vacuum/high-integrity castings.
Can EN AC-46100 be formed, bent or molded?
Excellent HPDC alloy: wide freezing-range fluidity fills 1–2 mm walls, Fe content prevents die soldering; keep melt clean and degassed, and do not solution treat standard castings.
What surface finishes work on EN AC-46100?
Best finished with chromate-free conversion coating plus powder coat or e-coat; decorative anodizing is dark and blotchy, hard anodizing only for wear; shot blast and impregnate porous parts before plating.

EN AC-46100-T5 — frequently asked
What is EN AC-46100-T5 used for?
EN AC-46100-T5 is typically used for thin-wall housings, die-cast covers and small brackets. In short: best fluidity for thin walls; fe-tolerant HPDC alloy; lowest machinability of group.
What is the yield strength of EN AC-46100-T5?
EN AC-46100-T5 has a typical yield strength of 175 MPa (25.4 ksi) and a tensile strength of 265 MPa (38.4 ksi) — weaker than 55% of aluminum grades. Strength varies by condition: see the 2 listed tempers.
Is EN AC-46100-T5 easy to machine?
Reasonably — machinability is rated good (65/100, better than 62% of aluminum grades). Machines freely with PCD or polished-flute carbide at high speed; eutectic Si is abrasive so avoid HSS, and expect porosity to break through on deep pockets and sealing faces.
Can EN AC-46100-T5 be welded?
Not readily — weldability is rated poor (25/100). Not recommended for structural welds — entrapped die-cast gas blisters and Cu promotes hot cracking; use 4047/4145 filler, laser or friction stir only on vacuum/high-integrity castings.
What surface finishes work on EN AC-46100-T5?
Best finished with chromate-free conversion coating plus powder coat or e-coat; decorative anodizing is dark and blotchy, hard anodizing only for wear; shot blast and impregnate porous parts before plating.
Can EN AC-46100-T5 be formed, bent or molded?
Excellent HPDC alloy: wide freezing-range fluidity fills 1–2 mm walls, Fe content prevents die soldering; keep melt clean and degassed, and do not solution treat standard castings.
What is the maximum service temperature of EN AC-46100-T5?
EN AC-46100-T5 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 EN AC-46100-F and EN AC-46100-T5?
F is the default condition — standard and essentially only commercial condition: as-cast HPDC parts, no heat treatment. T5: optional low-temperature age used to stabilise dimensions and slightly raise yield strength without blistering the die casting. Yield strength is 150 MPa in F versus 175 MPa in T5.
