The temperature gradation from the inner wall of the mould to the outside face of the mould can cause serious distortion problems, and Metallurgical Copper Mould Tube is imperative that the correct alloy is chosen for the various operating conditions. Square Copper mould tube STANDARD MATERIALS Phosphorus de-oxidised copper This alloy has been proven to be excellent for the manufacture of moulds in the continuous casting of billets. The main composition of this alloy are Cu +Ag 99.90min, P0.0015 / 0.040. Copper -Silver alloy The addition of a small amount of silver, whilst not increasing the melting point of copper, does increase the recrystallisation temperature by almost 100â??, and also helps to give better thermal conductivity at the operating temperatures. This alloy is normally used in moulds for the continuous casting of blooms and slabs .In this case, the moulds are much thicker than in the billet moulds, and the moulds temperature can be higher. The main composition of this alloy are Cu+Ag99.90 min. Ag 0.08 / 0.12 O 0.004 / 0.012.
