Working with ZL110 F-S
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 F-S — frequently asked
What is ZL110 F-S used for?
ZL110 F-S 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 F-S?
ZL110 F-S has a typical yield strength of 100 MPa (14.5 ksi) and a tensile strength of 135 MPa (19.6 ksi) — weaker than 84% of aluminum grades. Strength varies by condition: see the 7 listed tempers.
Is ZL110 F-S easy to machine?
Reasonably — machinability is rated good (58/100, worse than 54% 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 F-S 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 F-S?
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 F-S 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 F-S?
ZL110 F-S 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 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.
