The chemical composition is pure: high carbon, low sulfur, tiny nitrogen, slightly less harmful impurity.
Physical form: look clean, without impurities, absorption quick, high absorptivity.
The microstructure form: fine quality of crystal, effectively improve casting brand and performance.
Product properties stable: increase carbon stable effect, absorption effect is good, and the temperature effect is clear, and don't return slag.
