Compare all 4 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
SDefault Sand cast | Choose the general-purpose as-sand-cast state for medium and large worm gears, bearing sleeves and structural castings in one-off or small-batch production at 480 MPa tensile. | 195 | 480 | 25 | 105 HB | 21 % IACS |
Permanent (metal) mould cast | Pick metal mould casting for volume production of small and medium parts: fast cooling and a fine structure give 510 MPa tensile and 115 HB, above sand cast, with 22 % elongation. | 230 | 510 | 22 | 115 HB | 20.5 % IACS |
Continuous cast | Choose continuously cast bar and tube stock when a uniform, dense structure is to be machined directly into sleeves, nuts and guide parts at 515 MPa tensile and 22 % elongation. | 230 | 515 | 22 | 115 HB | 20.5 % IACS |
Centrifugal cast | Use centrifugal casting for sleeve, bearing shell and worm-gear blanks: the dense structure with few pores or inclusions reaches 520 MPa tensile, equal to or better than permanent mould. | 235 | 520 | 22 | 118 HB | 21 % IACS |
What is ZCuZn35Al2Mn2Fe1?
ZCuZn35Al2Mn2Fe1 is a high-strength complex cast brass alloyed with aluminium, manganese and iron, comparable to EN CC765S. Default-condition properties are 195 MPa yield, 480 MPa tensile, 25% elongation and about 105 HB, with service to 200 °C, so it is used for sand, permanent-mould, centrifugal and continuous castings that carry load and slide against steel. Machinability is moderate at roughly 30% of free-cutting brass and the iron-rich hard phases abrade tooling; fusion welding is limited to repair. For higher strength and hardness in the same family, step up to ZCuZn26Al4Fe3Mn3. ZCuZn35Al2Mn2Fe1 has a density of 8.5 g/cm³ (0.307 lb/in³), lighter than 65% of copper alloy grades. It melts at 880°C (1,616 °F). ZCuZn35Al2Mn2Fe1 has a yield strength of 195 MPa (28.3 ksi) and a tensile strength of 480 MPa (69.6 ksi) — weaker than 56% of copper alloy grades. Elongation at break is 25% and the elastic modulus is 100 GPa (14.5 Msi).

Working with ZCuZn35Al2Mn2Fe1
Is ZCuZn35Al2Mn2Fe1 easy to machine?
Machinability is about 30% of free-cutting brass, and the iron-rich hard phases wear cutting edges. Use carbide tooling with a large positive rake at moderate speed with ample coolant.
Can ZCuZn35Al2Mn2Fe1 be welded?
Repair welding is possible by GTAW/GMAW with aluminium-bronze or silicon-bronze filler. Preheat to 150-200 °C, control zinc evaporation and the aluminium oxide film, and cool slowly after welding to avoid cracking.
Can ZCuZn35Al2Mn2Fe1 be formed, bent or molded?
Casting alloy: pour at approximately 1000-1050 °C using bottom gating and steady mould filling, with enough feeders to prevent slag entrapment and shrinkage porosity. Keep wall-thickness transitions gradual.
ZCuZn35Al2Mn2Fe1 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.

What surface finishes work on ZCuZn35Al2Mn2Fe1?
Can be machined and polished to a mirror finish, nickel- or chrome-plated, or chemically passivated. Not anodizable; in seawater service combine with sacrificial anodes to limit dezincification.

ZCuZn35Al2Mn2Fe1 — frequently asked
What is ZCuZn35Al2Mn2Fe1 used for?
ZCuZn35Al2Mn2Fe1 is typically used for gears, bushings and worm wheels. In short: high-strength complex brass; good wear resistance; moderate machinability only.
What is the yield strength of ZCuZn35Al2Mn2Fe1?
ZCuZn35Al2Mn2Fe1 has a typical yield strength of 195 MPa (28.3 ksi) and a tensile strength of 480 MPa (69.6 ksi) — weaker than 56% of copper alloy grades. Strength varies by condition: see the 4 listed tempers.
Is ZCuZn35Al2Mn2Fe1 easy to machine?
Not especially — machinability is rated fair (35/100, better than 51% of copper alloy grades). Machinability is about 30% of free-cutting brass, and the iron-rich hard phases wear cutting edges. Use carbide tooling with a large positive rake at moderate speed with ample coolant.
Can ZCuZn35Al2Mn2Fe1 be welded?
With care — weldability is rated fair (35/100). Repair welding is possible by GTAW/GMAW with aluminium-bronze or silicon-bronze filler. Preheat to 150-200 °C, control zinc evaporation and the aluminium oxide film, and cool slowly after welding to avoid cracking.

What is the maximum service temperature of ZCuZn35Al2Mn2Fe1?
ZCuZn35Al2Mn2Fe1 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 ZCuZn35Al2Mn2Fe1-S and ZCuZn35Al2Mn2Fe1-Li?
S is the default condition — choose the general-purpose as-sand-cast state for medium and large worm gears, bearing sleeves and structural castings in one-off or small-batch production at 480 MPa tensile. Li: use centrifugal casting for sleeve, bearing shell and worm-gear blanks: the dense structure with few pores or inclusions reaches 520 MPa tensile, equal to or better than permanent mould. Yield strength is 195 MPa in S versus 235 MPa in Li.
