CA103 material is a high strength alloy that offers the combination of high wear resistance and corrosion resistance in marine environments and many acidic environments. It is also hot workable and relatively easy to machine, making it a popular choice of aluminium bronze.

This grade is not currently covered by any European specifications but due to its popularity amongst our customers Columbia Metals continues to hold a comprehensive range of sizes in stock ensuring continuity of supply.
