Copper Mould Tube

Materials of CCM Copper Mould Tube：

The materials of copper mould tubes should be the ones with good tensile strength, fatigue strength, proper hardness, low elongation and high heat conductivity coefficient. As a result, material like phosphorous deoxidize copper (CU-DHP) , Silver bearing (CUAG), CR-ZR-CU are widely accepted by users worldwide.

Coatings:Copper has lower hardness which leads to lower anti-abrasive property. Therefore, the area at the lower part of the moulds, where the stress increases drastically due to shells, will be more severely worn. To increase the life time of copper moulds, Uniform mould interior surface plating with suitable hardness is needed. Most of the copper mould tubes for small size billet casting are not used in any casting system where there are rigid casting stream support, therefore they are very sensitive to be worn. We use hard chrome plating to increase the life of mould tubes. The plating thickness will be controlled in the best range. Based on our years of experience, we are able to provide Cr coating, Ni-Cr coating, Ni-Fe coating to meet the various demands of customers both at home and abroad.
