Copper (Pure)CW024A (C106) Sheet & Tube

A phosphorous deoxidised non-arsenical copper that is 99.9% pure.

C106/CW024A is the preferred grade for non-electrical purposes such as fasteners, roofing sheet, plumbing tube and other general engineering and constructional applications. The alloy comes into its own where the manufacture of the component or plant involves welding or brazing.

This grade of copper is not susceptible to hydrogen embrittlement which can be a serious risk with non-deoxidised grades.

Used in architectural applications, C106 has asaethetic value and and can also be used for plating and polishing.
