Soundness Rare Earth Alloys With Lower MgO For Automobile Industry
Competitive Advantage:
Unique composition of special nodularizers is welcomed and it can be made and sipplied at convenience.
Supplied in the form of grains(5-25mm) or following special requirement. Packed plastic braids with inner wetresistant plastic film. Per packed parcel is 25kg n.w
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%.
Applications:Mainly used in automobile industry, Mechanical casting, Ductile iron pipes and Other metallurgical industry.The addition of magnesium (Mg) causes spheroidal graphite to grow.
