CZ126 (CW707R) is an arsenical brass available in tubular form. It contains 70% copper 30% zinc with a small addition of arsenic, which improves the corrosion resistance without affecting the ductility and forming characteristics of the material. With reasonable strength levels this alloy is utilised in heat exchangers, condensers and in other components requiring general purpose tube. This material offers a good workability and can be manipulated by a number of techniques. It also lends itself to soldering and brazing.
