ZCuAl03Sn09 Solid Aluminum Bronze Sheets 100mm*100mm Thick:6/8/10/12/15/16/20mm

ZCuAl03Sn09 is a Chinese national standard designation for a copper alloy containing approximately 3% aluminum and 9% tin. The addition of tin distinguishes it from simpler aluminum bronzes (such as C95400), giving it improved corrosion resistance in seawater and industrial fluids, as well as better sliding wear characteristics. It is commonly used for bushings, bearing liners, and wear plates where both strength and corrosion resistance are required.

For light-duty bushings with thin walls (2–4 mm finished wall), the 6 mm or 8 mm plate gives enough stock for boring and finishing. Medium-duty applications with 4–6 mm finished walls typically start from 10 mm or 12 mm stock. Heavy-duty or large-bore bushings requiring walls above 6 mm should use 15 mm, 16 mm, or 20 mm plate. Always add at least 1–2 mm of machining allowance to your finished wall dimension when selecting thickness.

Yes. ZCuAl03Sn09 machines well with both carbide-tipped and HSS tooling. A band saw or cold saw with a bi-metal blade handles cross-cutting cleanly. For milling and turning, use sharp tooling, moderate cutting speeds, and a suitable cutting fluid (soluble oil or neat cutting oil) to achieve smooth surface finishes and extend tool life. Avoid dry cutting on heavier passes.

Yes. The combination of aluminum and tin in the copper matrix provides solid resistance to seawater corrosion and atmospheric oxidation. It is widely used in marine hardware, propeller shaft bushings, and offshore equipment components. For prolonged immersion in aggressive chemical environments, contact us to confirm suitability for your specific application.

The 100 × 100 mm (3.94 × 3.94 in) format is a standard small-plate blank suited for components up to roughly 90–95 mm in their largest dimension after machining allowance. Common uses include square wear pads, round bushings up to ~90 mm outer diameter, and small bearing liners. If your finished part exceeds these dimensions, contact us — larger plate sizes may be available.

Order 1 piece if you are making a single component or testing the material for a new design. Order 2 or 3 pieces if you need spares for a matched set (such as paired bearing liners), want a backup blank in case of a machining error, or are producing a small batch of identical parts. Ordering multiple pieces in one transaction is more economical per unit than separate orders.

Standard brass (CuZn alloys) offers good machinability but lower strength and wear resistance than aluminum bronze. Phosphor bronze (CuSn with phosphorus) has good fatigue resistance but is softer under heavy sliding loads. ZCuAl03Sn09 aluminum-tin bronze sits between these in terms of hardness and wear resistance, offering better load-bearing capacity than brass and comparable or better corrosion resistance than phosphor bronze in many environments. It is the preferred choice when both wear resistance and corrosion resistance are required simultaneously.
