Core less non-ferrous metal melting refractory series: DRA-NC/NG
The NC series and NG series are used for low-temperature alloys such as copper/copper alloys and rare earth magnesium, respectively. Their excellent sintering performance ensures the strength of the lining material throughout the heating process. At the same time, this series of products has strong resistance to penetration, cracking, wetting and erosion, corrosion resistance, and volume stability.
