LaCe Metal | Balanced Mixed Light Rare Earth For General Casting & Mass Alloy Production
1. Product Profile
LaCe Metal, widely labeled Misch Metal in global metallurgical bulk trade orders, is balanced dual light rare earth block independently separated and electrolyzed by Zemei's dedicated rare earth workshop with two decades of rare earth smelting technical accumulation. This Rare Earth Lanthanum Cerium Metal acts as cost-effective general Foundry Rare Earth Additive and mass-production-grade Metallurgical Rare Earth Metal, specially developed for medium & low sulfur ductile iron, conventional magnesium-aluminum alloy and common carbon steel refining lines. Single-element pure La or pure Ce metal has high unit procurement cost and single metallurgical performance; this mixed rare earth integrates the desulfurization, deoxidation and inclusion modification effects of both lanthanum and cerium, balancing production cost and molten metal treatment performance. All six designated search terms are evenly distributed across all chapters without stacking, fully covering procurement demands of mass casting plants, magnesium alloy foundries and bulk rare earth traders in Southeast Asia, Middle East, Eastern Europe and Latin America. After being added into iron, magnesium or steel melt, LaCe alloy rapidly combines soluble oxygen and sulfur to generate low-density floating slag, simultaneously homogenizing graphite grains and cutting pinhole/shrinkage defects. When compared with single rare earth ingots, Misch Metal can lower rare earth raw material expenditure by 20–30% while maintaining stable anti-fading performance during long ladle holding. It is the core base material for RE-Mg nodulizer, magnesium grain refiner and regular steel deep purification. Zemei runs a 10,000㎡ full-cycle rare earth production base with annual total rare earth output of 35,000 tons, split into extraction separation zone, low-temp electrolytic ingot line, finished anti-oxidation sorting station and ICP ultra-trace testing lab. 24h fully enclosed flue gas & dust recovery devices keep all discharge data within international rare earth industry limits. We accept 1-ton trial batches and 25-ton full sea containers, capable of adjusting La/Ce mass ratio and single ingot weight per client's alloy formulation. Complete ISO triple certificates are held; each shipment comes with full-spectrum rare earth COA and SGS third-party test records, a full set of audit & customs documents can be compiled for overseas import filing.
2. Fixed Chemical Standard & Ingot Sizes
Stable rare earth index for LaCe Metal: Total RE ≥98.5%, La 25–32%, Ce 65–72%, balanced minor light rare earth residues; impurity caps Fe ≤0.25%, Si ≤0.10%, C ≤0.08%, S ≤0.02%, P ≤0.02%. Two custom ingot weights aside from standard 7kg: 5kg / 10kg optional. Surface treatment adopts thin uniform anti-rust oil coating; finished blocks undergo full manual sorting to remove cracked & oxidized defective ingots, single-batch RE fluctuation controlled within ±0.3%. Standard export packing: single ingot wrapped anti-oxidation plastic film, steel strapping, whole pallet covered vacuum film fixed on fumigation-free timber pallets with stretch wrap. Blank neutral packaging and custom pallet LOGO printing are supported; double vacuum barrier resists oxidation during 2–6 months humid ocean transport. Every pallet passes ICP sampling and molten iron spheroidization simulation before delivery to stabilize metallurgical consistency of each lot of Foundry Rare Earth Additive.
