1.65-1.70g graphite electrode for welding electrode: As a kind of structural material, the fine-grained graphite rod material is made of high quality calcined petroleum coke and modified coal asphalt through a specific formula and hot working process.The maximum particle size of this material is only 0.8mm.
The Fine-grained graphite rod has excellent mechanical property.And the surface becomes smooth and delicate after processing.
The fine grained graphite rod specification,size and property can be machined according to customer's actual demand.
Max.Length:2500mm Max.Width;800mm Max.Height 500mm
Max.Diameter:900mm Max.Length :2200mm
We can supply the demand of product spec.,size and dimension ,according to the customer's requirements
