CA104 / BSB23 / DTD197A


CA104 / BSB23 / DTD197A

CA104 / BSB23 / DTD197A is the most commonly used grade of aluminium bronze in the United Kingdom. It is mainly utilised for its high strength and its excellent resistance to erosion and corrosion in seawater and many other aggressive environments. In addition, the alloy offers very good wear and abrasion resistance, an ability to withstand shock loading and the retention of properties at cryogenic temperatures.

Purchased by Columbia Metals to conform to British standard CA104, the aerospace standards BSB23 and DTD197A and the European standard BS EN12163:CW307G, this material is available to four releases to ensure the customer has the exact specification they require.
