| INTRODUCTION: |
carbon brush block for brush
Isostatic graphite block is a new type of material.Graphite block is usde in precision tool,aerospace industry ,war industy ,chemical industry.ect .They are of high-strength ,high purity,low resisticity ,resistance to high temperature ,good resistance to shake and oxidation ,and tend to be processed elaborately.
Advantages of carbon brush block :
1,high strength,high hardness
2,good heat-resistance, low porosity
3,anti-abrasion,anti-scour
4,high purity graphite
Application of carbon brush block :
1, photovoltaic industry
2,Precision casting industry ,coper continuous parts
3, EDM graphite, brush
4, crucible for melting rare metals
5,machine analysis container
6, alloy industry, sintering molds
