high purity 38-44% Si, 4-6% Mg, 0.8-1.5% Re, 1.5%max Ca, 1.0% max Al

Soundness in microstructures with omogeneous composition, littlesegregation and lower MgO content. Stable and even lasting with highabsorption of Mg. Much smaller and globular graphite and highnodularization efficency when treted.

Nodularization temperature is recommended at 1400~1450when melted from a cupola, or at 1450~1500 when from anelectric furnace. Added at 1.5~1.8% when sulphur in the liquidcast iron is as high as 0.065~0.09%, or 1.4%~1.5% when sulphur is as high asa 0.05~0.065%.
