| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
FDefault As fabricated | Standard as-cast condition for general-purpose housings and brackets where cost and dimensional stability matter more than peak strength. | 100 | 190 | 2 | 60 HB | 37 % IACS |

Solution heat treated and under-aged | Under-aged compromise giving somewhat better elongation and impact toughness than T6 at moderately reduced strength. | 150 | 210 | 3 | 75 HB | 31 % IACS |
Solution heat treated and artificially aged | Choose when maximum strength and hardness are needed from sand or permanent-mould castings; ductility stays low and distortion from quenching must be allowed for. | 220 | 260 | 1.5 | 90 HB | 39 % IACS |
What is EN AC-43200?
EN AC-43200 (AlSi10Mg(Cu)) is a copper-modified near-eutectic Al-Si-Mg casting alloy used mainly for pressure die casting, where the copper raises strength and machinability. Default as-cast properties are 190 MPa tensile, 100 MPa yield, 2 % elongation and 60 HB, with 145 W/m·K conductivity and a 555 °C melting point; F, T5, T6 and T64 conditions are on file. The copper reduces corrosion resistance and raises hot-cracking risk, and ductility is modest with service capped near 150 °C. Use EN AC-43100 (AlSi10Mg(b)) where corrosion resistance or weldability matters more than strength. EN AC-43200 has a density of 2.65 g/cm³ (0.0957 lb/in³), lighter than 90% of aluminum grades. It melts at 555°C (1,031 °F). EN AC-43200 has a yield strength of 100 MPa (14.5 ksi) and a tensile strength of 190 MPa (27.6 ksi) — weaker than 84% of aluminum grades. Elongation at break is 2% and the elastic modulus is 72 GPa (10.4 Msi).

Working with EN AC-43200
Is EN AC-43200 easy to machine?
Machines well with PCD or coated carbide at high speed; the eutectic silicon is abrasive, so use rigid setups, sharp positive-rake tools and copious coolant.
Can EN AC-43200 be welded?
Weldable by TIG/MIG with 4043/AlSi12 filler, but the copper content raises hot-cracking risk and porosity from entrapped gas makes die castings generally unsuitable for fusion welding.
Can EN AC-43200 be formed, bent or molded?
Excellent fluidity and low hot-tearing tendency for sand, permanent-mould and pressure die casting; design uniform sections and adequate feeding to avoid shrinkage porosity — cold forming is not possible.

EN AC-43200 — frequently asked
What is EN AC-43200 used for?
EN AC-43200 is typically used for die-cast housings, brackets and automotive gearbox components. In short: copper-boosted AlSi10Mg; higher strength, lower corrosion; die-casting workhorse.
What is the yield strength of EN AC-43200?
EN AC-43200 has a typical yield strength of 100 MPa (14.5 ksi) and a tensile strength of 190 MPa (27.6 ksi) — weaker than 84% of aluminum grades. Strength varies by condition: see the 4 listed tempers.
Is EN AC-43200 easy to machine?
Reasonably — machinability is rated fair (50/100, worse than 65% of aluminum grades). Machines well with PCD or coated carbide at high speed; the eutectic silicon is abrasive, so use rigid setups, sharp positive-rake tools and copious coolant.
Can EN AC-43200 be welded?
Yes — weldability is rated good (65/100). Weldable by TIG/MIG with 4043/AlSi12 filler, but the copper content raises hot-cracking risk and porosity from entrapped gas makes die castings generally unsuitable for fusion welding.
What surface finishes work on EN AC-43200?
Takes hard/protective anodizing with a dark grey appearance; chromate/phosphate conversion coats, powder coating and painting are the usual routes for corrosion protection.
Can EN AC-43200 be formed, bent or molded?
Excellent fluidity and low hot-tearing tendency for sand, permanent-mould and pressure die casting; design uniform sections and adequate feeding to avoid shrinkage porosity — cold forming is not possible.
What is the maximum service temperature of EN AC-43200?
EN AC-43200 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-43200-F and EN AC-43200-T6?
F is the default condition — standard as-cast condition for general-purpose housings and brackets where cost and dimensional stability matter more than peak strength. T6: choose when maximum strength and hardness are needed from sand or permanent-mould castings; ductility stays low and distortion from quenching must be allowed for. Yield strength is 100 MPa in F versus 220 MPa in T6.
How much does EN AC-43200 cost?
