Aluminum Bronze Sheet Plate ZCuAl03Sn09 Metal Panel 6mm-40mm Thick, 100x100mm

Start with the thickness closest to your finished bore depth plus at least 2–3mm of machining allowance on each face. For most small bushings (wall thickness 4–10mm), the 10mm or 12mm plates are a practical starting point. For heavier-duty bearing seats requiring walls above 15mm, step up to the 20mm or 25mm option to leave adequate stock for boring and facing.

ZCuAl03Sn09 aluminum bronze typically offers higher tensile strength (490–590 MPa) than most phosphor bronze grades (C51000/C54400 range: 310–520 MPa) and comparable or better hardness. It also outperforms phosphor bronze in corrosion resistance in seawater and oxidizing environments, making it the preferred choice for marine and chemical-processing applications.

Yes. The aluminum content in ZCuAl03Sn09 promotes the formation of a stable aluminum oxide surface layer that resists seawater corrosion, biofouling, and many chloride-containing environments. It is widely used for marine shaft bushings, propeller hubs, and underwater hardware where long service life without coating is required.

TIG and MIG welding are both feasible using a compatible aluminum bronze filler rod (e.g., ERCuAl-A2). Pre-heat to approximately 150–200°C for thicker sections (20mm+) to reduce thermal stress. Brazing is possible with silver-based filler at appropriate flux. Avoid oxyacetylene welding, which can cause porosity in aluminum bronze alloys.

Carbide-tipped or solid carbide tooling is recommended for best surface finish and tool life. ZCuAl03Sn09 machines similarly to other aluminum bronzes — use moderate cutting speeds (typically 60–120 m/min for turning), adequate coolant, and positive rake angles to prevent built-up edge. HSS tooling can be used for light cuts but will wear faster on thicker sections.

The 100×100mm blank is intended as a starting stock for parts that fit within that footprint after machining. If your finished part requires a larger footprint, contact us — we may be able to source larger plate sizes or custom-cut dimensions. For parts smaller than 100×100mm, you can saw or mill the blank down to your required outline before further machining.

These plates are supplied in a mill/saw-cut condition, meaning surface flatness and parallelism are as-cut rather than ground or lapped. For applications requiring tight thickness tolerances (±0.1mm or better), plan to face-mill or surface-grind both sides before using the plate as a reference datum. For general structural or wear-plate applications, the as-cut finish is typically adequate.
