ASTM B88, ASTM B88m, ASTM B280, BS EN standards, SWG.

The copper used in the manufacture of tubes is phosphorus deoxidized copper Cu-DHP defined by British Standard BS. 6017: 1981. This also corresponds to the ISO denomination Cu-DHP.

The minimum copper content is 99.85% and the residual phosphorus content is between 0.013 and 0.050%. This deoxidized copper is not affected by reducing atmospheres and consequently is well suited to welding and brazing. The density of copper is 8.9 g/cm³. its melting point is 1083 ⁰C and its coefficient of linear expansion is 16.8 x 10^-6 per ⁰C (between 20^oC and 100^oC).
