Working with EN AC-43200-T5

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.

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.

EN AC-43200-T5 — frequently asked

What is EN AC-43200-T5 used for?

EN AC-43200-T5 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-T5?

EN AC-43200-T5 has a typical yield strength of 130 MPa (18.9 ksi) and a tensile strength of 200 MPa (29 ksi) — weaker than 73% of aluminum grades. Strength varies by condition: see the 4 listed tempers.

Is EN AC-43200-T5 easy to machine?

Reasonably — machinability is rated good (60/100, worse than 51% 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-T5 be welded?

With care — weldability is rated fair (42/100). 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-T5?

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-T5 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-T5?

EN AC-43200-T5 is rated for continuous use to about 160°C (320 °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.
