The optimal copper alloy for propeller manufacturing, in just the necessary amounts and with a short delivery time.
In the marine propeller industry, materials that balance corrosion resistance and strength are in demand. It is particularly important to be resistant to corrosion and wear in seawater environments and to maintain performance over long periods. Inappropriate material selection can lead to early deterioration of the propeller and a decline in performance, potentially resulting in increased operating costs and safety issues. Our company offers the optimal materials for propeller manufacturing, including phosphor bronze, nickel silver, and beryllium copper, to meet our customers' needs. We also provide long products and can cut and sell them to the necessary length for shafts. 【Application Scenarios】 - Propeller manufacturing - Ship component (shaft) manufacturing - Marine equipment manufacturing 【Benefits of Implementation】 - Balancing corrosion resistance and strength - Ability to purchase only the necessary amount of materials - Short delivery times - Cost reduction
