Global Magnesium Ingot Supply: Applications, Sizing Options, and Market Dynamics

Magnesium ingots serve as a fundamental primary material across non-ferrous metallurgy, chemical production, and iron founding. With China supplying over 90% of the world's primary magnesium, securing a reliable, direct factory supply chain is essential for industrial plants operating across Europe, the Americas, the Middle East, and Asia.

 

Key Customer Groups & Industrial Applications

Pure magnesium ingots (typically 99.90% to 99.95% purity) are tailored to meet the strict metallurgical requirements of three primary downstream sectors:

  • Magnesium Alloy Manufacturers: Pure magnesium ingots form the base metal for producing lightweight structural alloys (such as AZ91D and AM60B) widely used in automotive die-casting, aerospace components, and 3C electronics.

  • Magnesium Powder Plants: High-purity ingots are milled, atomized, or ground into reactive magnesium powder. These powders are critical for hot metal desulfurization in steelmaking, pyrotechnic manufacturing, and chemical reagents.

  • Nodulizer & Ferroalloy Producers: Magnesium is the core active element in manufacturing Rare Earth Ferrosilicon Magnesium (FeSiMg) nodulizers. Ductile iron foundries rely on these additives to change graphite structures from flakes into spheres. Learn more about our Ferrosilicon Magnesium Nodulizer solutions.

Standard Ingots vs. Small Ingots: Understanding the Price Premium

While standard 7.5 kg (± 0.5 kg) ingots remain the global benchmark for bulk remelting, smaller ingot sizes (ranging from 100g, 200g, 500g, to 1kg and 3kg) are increasingly favored by specialized producers.

Small magnesium ingots command a higher market price per ton than standard blocks due to several operational advantages:

  • Processing & Casting Costs: Manufacturing small pigs requires specialized continuous casting molds, higher labor inputs, and precise weight management.

  • Rapid Melting Rate: The higher surface-area-to-volume ratio drastically reduces melt times in induction furnaces, lowering operational energy consumption.

  • Precise Batch Dosing: Small ingots allow foundry technicians and nodulizer plants to make fine weight adjustments without the safety hazards and labor of manually breaking large blocks.

  • Reduced Handling Equipment: Eliminates the need for heavy secondary crushing or mechanical breaking lines at powder and alloy facilities.

Technical Specifications & Chemical Composition

Our primary magnesium ingots are smelted from high-grade dolomite using advanced thermal reduction processes, ensuring minimal residual impurities:

  • Magnesium (Mg): 99.90% Min / 99.95% Min

  • Iron (Fe): ≤ 0.04%

  • Silicon (Si): ≤ 0.02%

  • Nickel (Ni): ≤ 0.001%

  • Copper (Cu): ≤ 0.004%

  • Aluminum (Al): ≤ 0.02%

  • Standard Sizing: 7.5kg ± 0.5kg standard ingots, or customized small ingots (100g – 3kg).

Global Logistics & Export Packaging

To prevent surface oxidation and transit damage during long-distance ocean freight, all shipments adhere to export-grade packaging standards:

  • Palletizing: Ingots are stacked on sturdy magnesium or wood pallets, bound with high-tensile steel strapping.

  • Moisture Protection: Wrapped in double-layer heavy-duty polyethylene shrink film with anti-corrosion desiccant packs.

  • Custom Shipping: Available in 20ft container loads, packaged for safe handling via forklift at destination ports.
