Our Aluminum-Rare Earth (Al-RE) range helps control microstructure, improve casting quality, and enhance stability at elevated temperatures. It supports both foundry and wrought products. Backed by provincial-level R&D, multi-site production, and certified systems, we deliver consistent chemistry, fast dissolution, and reliable traceability.
Al-La: Lanthanum improves fluidity and lowers hot cracking in casting alloys. Typical La 5–20%, with tight tramp control.
Al-Er: Erbium forms stable dispersoids (e.g., Al3Er) for grain refinement and high-temperature stability. Typical Er 1–10%.
Al-Ce: Cerium aids castability and modifies eutectic Si in Al-Si systems to reduce porosity. Typical Ce 5–20%.
Al-Y: Yttrium enhances high-temperature strength and oxidation resistance. Typical Y 2–10%, tuned to application targets.
Al-Nd: Neodymium supports dispersion strengthening and microstructure refinement. Typical Nd 5–20%.
Grain refinement and structure control: Finer, more uniform grains and dispersoids reduce defects and support dimensional stability.
Silicon modification in Al-Si: La and Ce shift eutectic Si toward a fibrous form, improving machinability and impact response.
Elevated-temperature performance: Er and Y form thermally stable phases that help sustain creep resistance and strength.
Melt cleanliness and corrosion behavior: These elements can tie up impurities, supporting cleaner melts and stable performance.
All grades are available as ingots, waffle ingots, shots, and compact tablets. Geometries are designed to shorten dissolution time and promote uniform distribution with minimal inclusions. Moisture-managed packaging with sealed liners and labeled batches supports safe storage and straightforward lot traceability.
Al-Si die casting and permanent mold: Better fluidity, lower shrinkage porosity, and improved surface consistency in high-throughput lines.
Wrought series (3xxx, 5xxx, 6xxx): Finer recrystallized structures and improved stability in rolled and extruded products.
Electrical and thermal conductors: Balanced additions help maintain conductivity while improving mechanical stability.
With AlTiB grain refiners: Strong nucleation and tight grain size control complement the effects of Al-RE additions.
With AlSr modifiers in Al-Si: La/Ce can fine-tune eutectic morphology alongside Sr for complex geometries.
With refining and degassing fluxes: Cleaner, degassed melts support predictable recovery and performance.
Operations are certified to IATF 16949:2016, ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018. In-line spectral analysis and controlled furnaces verify chemistry and melt cleanliness batch to batch. A multi-site footprint—including Harbin headquarters, Cangzhou plants, and a dedicated Anhui facility for master alloys, AlTiB refiners, and tablets—supports continuity and scalable output. Regional warehouses and distribution centers enable short lead times and responsive replenishment.
Chemistries, element levels, and forms are tailored to furnace type, charge routine, and target alloys to maximize recovery and consistency. Application engineers provide dosing plans, trial support, and guidance on timing, temperature windows, and interactions with refiners and fluxes.
What issues can these additions address? Coarse grains, unstable eutectic Si, hot cracking, and softening at high temperature.
How should dosage be determined? Pilot trials establish economical rates that reduce scrap and rework while meeting property targets.
How are these grades introduced into the melt? Add shots or tablets to the vortex or furnace mouth, hold for the defined time, and skim as needed. Clean, degassed melts improve recovery.
