Graphite sintering plates will be used in sintering of Ferro as well as Non ferrous alloys. Graphite Sintering Plates has properties of low resistance, high temperature, low oxidation, low cementite and long lifetime. The Plates and molds can be of desired shape and dimensions within the manufacturing size of blocks.
Good compact construction
High strength, heat resistance
Sodium corrosion resistances
High resistance to thermal shock
Low heat expansion coefficients
The Cathode Carbon blocks will be used in Aluminium, Ferro Alloy and other Allied Industries. The Cathode Carbon Blocks can be provided according to customer request sizes, specifications and Drawings.
