Compare all 7 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
F | Cheapest route for low-stress or large one-off sand castings where no heat treatment is applied. | 100 | 135 | 0.5 | 80 HB | 27 % IACS |
F | Chill-cast as-cast condition; finer structure raises strength ~25 % over sand casting with no heat-treat cost. | 120 | 165 | 0.6 | 82 HB | 27.5 % IACS |
T1 | Simple ageing of a sand casting to stabilise dimensions and lift hardness without distortion risk from quenching. | 120 | 155 | 0.4 | 90 HB | 29 % IACS |
T5 | Short low-temperature age used mainly to stabilise dimensions of machined castings with a modest hardness gain. | 135 | 185 | 0.6 | 88 HB | 28.5 % IACS |
T1-JDefault T1 | The usual production condition: chill casting plus ageing gives a good strength/cost balance and dimensional stability for engine and machine parts. | 155 | 210 | 0.5 | 92 HB | 29 % IACS |
T7 | Overaged for maximum dimensional and thermal stability in parts running hot for long periods, at some loss of strength versus T6. | 180 | 225 | 0.8 | 95 HB | 31 % IACS |
T6 | Highest-strength condition; choose for loaded pistons/heads where the quench distortion and extra cost are acceptable. | 215 | 260 | 0.5 | 105 HB | 27 % IACS |
What is ZL110?
ZL110 (ZAlSi5Cu6Mg, close to 333.0) is a GB Al-Si-Cu-Mg casting alloy in which about 5 % Si provides fluidity while a high copper level provides strength and hot hardness. It is produced as sand and permanent-mould castings in F, T1, T5, T6 and T7 conditions; the default data point is 210 MPa tensile, 155 MPa yield, 92 HB and service to 200 °C. Elongation is only 0.5 %, so it suits stiff, statically loaded parts rather than impact loading, and the high Cu content lowers corrosion resistance and makes fusion repair hot-crack prone. Choose an Al-Si-Mg alloy such as ZL114A when ductility or weld repair is required. ZL110 has a density of 2.8 g/cm³ (0.101 lb/in³), heavier than 81% of aluminum grades. It melts at 525°C (977 °F). ZL110 has a yield strength of 155 MPa (22.5 ksi) and a tensile strength of 210 MPa (30.5 ksi) — weaker than 63% of aluminum grades. Elongation at break is 0.5% and the elastic modulus is 72 GPa (10.4 Msi).

Working with ZL110
Is ZL110 easy to machine?
Machines freely with sharp carbide or PCD tooling and high speeds; the eutectic Si is abrasive, so expect tool wear and use flood coolant to avoid built-up edge.
Can ZL110 be welded?
Poor fusion weldability — the high Cu content promotes hot cracking; repair only with 4047/4145 filler, low heat input and preheat, then re-age.
Can ZL110 be formed, bent or molded?
Sand or permanent-mould cast only; good fluidity from the 5 % Si but feed heavily and use chills, as Cu widens the freezing range and raises shrinkage/hot-tear risk.

What surface finishes work on ZL110?
Anodising gives dark, uneven films — use chromate conversion, primer/paint or hard anodise for wear only; shot blasting and impregnation are common for pressure-tight castings.

ZL110 — frequently asked
What is ZL110 used for?
ZL110 is typically used for engine and gearbox housings, machine tool castings, pump and valve bodies, general mechanical castings, brackets and mounting bodies and pressure-tight impregnated castings. In short: high-copper ZL casting alloy; 200 °C service capability; very low elongation.
What is the yield strength of ZL110?
ZL110 has a typical yield strength of 155 MPa (22.5 ksi) and a tensile strength of 210 MPa (30.5 ksi) — weaker than 63% of aluminum grades. Strength varies by condition: see the 7 listed tempers.
Is ZL110 easy to machine?
Reasonably — machinability is rated good (62/100, better than 55% of aluminum grades). Machines freely with sharp carbide or PCD tooling and high speeds; the eutectic Si is abrasive, so expect tool wear and use flood coolant to avoid built-up edge.
Can ZL110 be welded?
Not readily — weldability is rated poor (22/100). Poor fusion weldability — the high Cu content promotes hot cracking; repair only with 4047/4145 filler, low heat input and preheat, then re-age.
What surface finishes work on ZL110?
Anodising gives dark, uneven films — use chromate conversion, primer/paint or hard anodise for wear only; shot blasting and impregnation are common for pressure-tight castings.
Can ZL110 be formed, bent or molded?
Sand or permanent-mould cast only; good fluidity from the 5 % Si but feed heavily and use chills, as Cu widens the freezing range and raises shrinkage/hot-tear risk.
What is the maximum service temperature of ZL110?
ZL110 is rated for continuous use to about 200°C (392 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ZL110 T1-J and ZL110 T6-J?
T1-J is the default condition — the usual production condition: chill casting plus ageing gives a good strength/cost balance and dimensional stability for engine and machine parts. T6-J: highest-strength condition; choose for loaded pistons/heads where the quench distortion and extra cost are acceptable. Yield strength is 155 MPa in T1-J versus 215 MPa in T6-J.
How much does ZL110 cost?
ZL110 is a standard-cost aluminum ($$), cheaper than about 71% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
