Cerium Rare Earth Metal | High Sulfur-Adapted Single Ce Rare Earth For Heavy Ductile Iron & High-Duty Alloys

1. Product Profile

Cerium Rare Earth Metal, abbreviated Ce Metal by global casting factories, is single-component high-activity pure cerium rare earth ingot via multi-stage impurity separation and low-temperature electrolytic refining of Zemei's professional rare earth production line with 20 years of smelting technology reserve. This Rare Earth Cerium Metal serves as high-efficiency Foundry Cerium Additive and heavy-duty grade Metallurgical Rare Earth Metal, mainly applied to high-sulfur recycled molten iron, thick-wall heavy ductile iron and high-strength alloy steel refining. Different from lanthanum metal which focuses on ultra-clean low-impurity alloys, Pure Cerium Metal owns superior sulfur-oxygen binding affinity, showing outstanding long anti-fading performance in high-sulfur molten metal environments. Six fixed cross-border keywords evenly distributed in all paragraphs, fully matching procurement demands of heavy machinery foundries, high-sulfur scrap iron casting plants and alloy steel manufacturers across Middle East, Southeast Asia and Eastern Europe. After being added into iron/magnesium/steel melt, Ce Metal rapidly reacts with sulfur & oxygen to form large floating composite slag, fundamentally eliminate subcutaneous pinhole and graphite coarsening defects on thick heavy castings, extend effective spheroidization holding time above 25 minutes. While LaCe mixed rare earth can only cope with medium-sulfur raw materials, single cerium targets severe high-sulfur recycled iron, cutting thick casting reject rate by 25–38%. Zemei's 10,000㎡ full-cycle rare earth base has annual output of 35,000 tons, equipped with dedicated cerium separating workshop, low-temp electrolytic ingot line, anti-oxidation finishing station and ICP full-spectrum testing lab. 24h closed flue gas & dust recovery meets international heavy casting environmental standards. We accept 1-ton trial batches and 25-ton full sea containers, customizable single ingot weight based on high-sulfur nodulizer formulas. Complete ISO triple certifications are ready; each shipment attaches full rare earth COA and SGS third-party inspection reports, full customs & audit documents can be sorted for overseas import filing.

2. Fixed Chemical Standard & Ingot Sizes

Stable purity standard of Ce Metal: Ce ≥99.90%, total RE ≥99.93%; impurity limits La ≤0.07%, Fe ≤0.02%, Si ≤0.01%, C ≤0.01%, S ≤0.008%, P ≤0.008%. Standard 7kg cerium ingot, optional 5kg / 10kg custom weights. Thin uniform anti-rust oil surface treatment; full manual sorting removes oxidized & cracked defective blocks, single-batch cerium fluctuation controlled within ±0.03%. Standard export vacuum packing: single ingot independent anti-rust plastic film, steel strapping, whole pallet vacuum film fixed on fumigation-free timber pallets. Neutral blank & pallet brand LOGO printing supported; dual vacuum anti-oxidation layer works for 2–6 months humid ocean transportation. Every pallet undergoes ICP sampling + high-sulfur molten iron spheroidization simulation before delivery to guarantee stable purification capacity of each lot of Foundry Cerium Additive.
