UNS C95200
ZCuAl10Fe3 (C95200) is an iron-bearing cast aluminium bronze, nominally 10 % Al with 3 % Fe, in which the iron refines the grain and forms hard kappa particles that raise wear resistance.

What is ZCuAl10Fe3?
ZCuAl10Fe3 (C95200) is an iron-bearing cast aluminium bronze, nominally 10 % Al with 3 % Fe, in which the iron refines the grain and forms hard kappa particles that raise wear resistance. It is a widely used casting grade offering 200 MPa yield, 540 MPa tensile, 20 % elongation and 120 HB (70 HRB) with useful strength to about 300 °C and good seawater corrosion resistance, available as sand, chill, centrifugal and continuous castings. Machinability is moderate (score 45) and the abrasive Fe/kappa particles wear tooling. For higher strength choose ZCuAl10Fe3Mn2, or ZCuAl8Mn13Fe3Ni2 for heavily loaded marine work. ZCuAl10Fe3 has a density of 7.5 g/cm³ (0.271 lb/in³), lighter than 98% of copper alloy grades. It melts at 1,045°C (1,913 °F). ZCuAl10Fe3 has a yield strength of 200 MPa (29 ksi) and a tensile strength of 540 MPa (78.3 ksi) — weaker than 54% of copper alloy grades. Elongation at break is 20% and the elastic modulus is 110 GPa (16 Msi).

Working with ZCuAl10Fe3
Is ZCuAl10Fe3 easy to machine?
Machines like a tough bronze — rigid setup, sharp positive-rake carbide, moderate speed with generous coolant; hard κ/Fe particles cause abrasive tool wear and long stringy chips.
Can ZCuAl10Fe3 be welded?
Weldable by GTAW/GMAW with matching Cu-Al filler (e.g. ERCuAl-A2), 150–250 °C preheat, argon shielding and thorough oxide removal; avoid overheating to limit brittle γ2 phase.
Can ZCuAl10Fe3 be formed, bent or molded?
A casting alloy only — pour at 1150–1200 °C with quiet bottom gating, generous risers and degassing; the alumina film makes turbulence-free filling essential.
ZCuAl10Fe3 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

|---|---|---|
| Al | 8.5 – 11 | 10 |
| Fe | 2 – 4 | 3 |
| Mnimpurity/optional | ≤ 1 | 0.3 |

| Cubalance, total impurities ≤1.0 % | balance |
What surface finishes work on ZCuAl10Fe3?
Polishes to a golden lustre and can be shot-blasted or passivated; electroplating and soldering require aggressive oxide removal or a nickel strike.

ZCuAl10Fe3 — frequently asked
What is ZCuAl10Fe3 used for?
ZCuAl10Fe3 is typically used for propellers, worm gears, bushings and valve seats. In short: workhorse aluminium bronze; wear- and seawater-resistant; abrasive on tooling.
What is the yield strength of ZCuAl10Fe3?
ZCuAl10Fe3 has a typical yield strength of 200 MPa (29 ksi) and a tensile strength of 540 MPa (78.3 ksi) — weaker than 54% of copper alloy grades. Strength varies by condition: see the 4 listed tempers.
Is ZCuAl10Fe3 easy to machine?
Reasonably — machinability is rated fair (45/100, better than 64% of copper alloy grades). Machines like a tough bronze — rigid setup, sharp positive-rake carbide, moderate speed with generous coolant; hard κ/Fe particles cause abrasive tool wear and long stringy chips.
Can ZCuAl10Fe3 be welded?
Yes — weldability is rated good (60/100). Weldable by GTAW/GMAW with matching Cu-Al filler (e.g. ERCuAl-A2), 150–250 °C preheat, argon shielding and thorough oxide removal; avoid overheating to limit brittle γ2 phase.

What is the maximum service temperature of ZCuAl10Fe3?
ZCuAl10Fe3 is rated for continuous use to about 300°C (572 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ZCuAl10Fe3-S and ZCuAl10Fe3-Li?
S is the default condition — general-purpose condition for larger, one-off or low-volume castings such as valve bodies, worm wheels and bearing housings. Li: best for bushings, sleeves and worm-wheel rims: dense, porosity-free wall with the highest strength and wear life. Yield strength is 200 MPa in S versus 240 MPa in Li.
