Deoxidising agents for Copper & Copper based alloys. D.O.TUBES are individual copper based tubes containing a variety of reagents. D.O.TUBES are specially designed to remove dissolved oxygen formed during the melting process. If this dissolved gas is allowed to remain in the melt it can seriously reduce mechanical properties and pressure tightness of the casting. Thus, D.O.Tubes are used to maintain the mechanical properties and reduce rejections due to defects.
Upon completion of the melting process using the appropriate covering and cleaning agents, the melt should be deoxidised to remove dissolved oxygen.
