                        The graphite block can be widely used in Mechanical Industry, as the carbon strip and carbon brushGraphite block, as one of the most important graphite products, is widely used in such field as metallurgy, mechanical,electronics and chemical industry and so on. It is vibration molded or extruded, molded, isostatic.carbonized and graphitized under precise technical control. Specificities 1. high strength 2. bearing high tempereture 3. anti-oxidant 4. corrosion-resistant 5. good thermal and electric conductivity 6. chemical stability 7. easy to be machining progressed 8. high lubricity Level Physical characteristics Granularity Body density Flexural strength Compressive strength Resistivity Thermal expansion Ash mm g/cm3 Mpa Mpa μΩ-m ×10-6/℃ % ZI-A3 ≤0.8 ≥1.74 ≥14.0 ≥32 ≤7.0 ≤2.5 ≤0.3 ZI-A2 ≥1.72 ≥13.5 ≥30 ≤7.5 ZI-A1 ≥1.68 ≥13.0 ≥28 ≤8.0 ZI-B2 ≤2.0 ≥1.72 ≥13.5 ≥32 ≤8.0 ZI-B1 ≥1.68 ≥13.0 ≥30 ≤8.5 ZI-B ≥1.58 ≥12.0 ≥25 ≤9.0 ZI-C1 ≤4.0 ≥1.68 ≥13.0 ≥30 ≤8.5 ZI-C ≥1.58 ≥12.0 ≥25 ≤9.0 Specification 400 x 400 x 1800mm,500 x 500 x 1900mm,540 x 450 x 2200mm,540 x 350 x 2700mm 520 x 400 x 2200mm,560 x 560 x 1850mm,400 x 630 x 2200mm,280 x 530 x 2800mm 630 x 630 x 2200mm,Ø600-Ø1500 x 450mm,Ø300-Ø500 x 1200-2200mm
