High Purity Magnesium Ingot is manufactured via thermal reduction (Pidgeon process) or electrolytic refining, followed by fluxless refining and precise casting. Designed for critical metallurgical applications, it delivers a minimum purity of 99.90% with tightly controlled transition metal impurities to prevent intergranular corrosion in downstream alloys.
Key Features
Low Iron & Nickel Content: Minimized levels of Fe and Ni prevent galvanic corrosion in structural magnesium and aluminum alloys.
Fluxless Refining Technology: Reduces non-metallic inclusions and chloride residue within the ingot matrix.
Uniform Grain Structure: Controlled solidification rates ensure consistent melting behavior and recovery rates in alloy furnaces.
Clean Surface Finish: Free from heavy oxidation, oil, slag, and embedded foreign matter.

Applications
Aluminium Alloy Production
Alloying element for 5xxx and 6xxx series structural aluminum used in marine and automotive sectors.
Titanium Production
Acting as a reducing agent in the Kroll process for sponge titanium extraction.
Magnesium Die-Casting Alloys
Base material for formulating AZ91D, AM60B, and ZK60 automotive and 3C electronic housings.
Chemical Synthesis
Grignard reagent preparation and metallurgical reduction of rare metals.
Cathodic Protection
Raw material for sacrificial anode casting to prevent pipeline and hull corrosion.
Quality Control & Manufacturing Capability
Production Capacity: Stable annual output supporting long-term enterprise supply agreements and consistent volume commitments.
Melting & Refining: Multi-stage vacuum distillation and protective gas shielding (SF6/CO2 mixture) prevent atmospheric oxidation during casting.
Analytical Testing: Every production lot is sampled and analyzed using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) to guarantee trace element compliance.
Traceability: Each bundle is stamped with heat numbers corresponding directly to the batch Mill Test Certificate (MTC).
Packaging & Shipping
Palletization: Stacked on ISPM 15 compliant heat-treated wooden pallets or fumigation-free composite export pallets to streamline international customs clearance.
Strapping: Secured with heavy-duty galvanized steel or PET bands.
Moisture Protection: Wrapped in multi-layer moisture-barrier plastic film with desiccant pouches inside sealed outer covers to prevent surface oxidation during ocean transit.
Standard Bundle Weight: Approx. 1,000 kg or 500 kg per pallet.

FAQ
Q: How do you prevent oxidation of the ingots during ocean freight?
A: Ingots are tightly wrapped in corrosion-inhibited plastic film, sealed against moisture ingress, and loaded into dry containers with embedded desiccants.
Q: Can you provide third-party inspection reports?
A: Yes. Pre-shipment inspection by SGS or Bureau Veritas can be arranged upon request prior to dispatch.
Q: What is the exact sampling method used for the chemical analysis?
A: Samples are drilled from top, middle, and bottom ingots of each specific heat lot and consolidated for multi-point ICP-OES testing.
