STANDARD MATERIALSsrus de-oxidised copperThis alloy has been proven to be exnt 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 alloyThe addition of a small amount of silver ,whilst not increasing the melting point of copper ,does increase the recrystallisation temperature by almost 100℃,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.
