In the hierarchy of magnesium products, Magnesium Ingots represent the primal, elemental form—the building block from which all other magnesium products are derived. As India’s manufacturing sector expands across automotive, aerospace, metallurgy, and chemical industries, the strategic procurement of high-quality magnesium ingots has become a critical concern for procurement managers and production heads. Unlike processed forms like granules or powder, ingots offer stability, cost-effectiveness, and versatility for various downstream applications.
This definitive guide provides comprehensive insights into purchasing magnesium ingots in India, covering everything from international standards to pricing dynamics, with expert perspective from Pentaphos.com, a leading supplier to India’s core industries. Whether you’re an alloy producer, chemical manufacturer, or metal trader, understanding the ingot market is essential for competitive advantage.
Understanding Magnesium Ingots: More Than Just Metal Blocks
Magnesium ingots are solidified blocks of pure or alloyed magnesium, typically produced via electrolytic or thermal reduction processes. They serve as the primary raw material for:
- Producing magnesium granules, powder, and turnings
- Manufacturing aluminum-magnesium alloys
- Creating magnesium-based sacrificial anodes
- Direct use in certain metallurgical processes
Physical Characteristics:
- Shape: Standard trapezoidal (pig) shape or customized
- Weight: Typically 7.5 kg per ingot (varies by standard)
- Surface: Should be clean with minimal oxidation, folds, or inclusions
- Markings: Heat/batch numbers, purity grade, manufacturer logo
Global Classification Systems: Understanding What You’re Buying

Frequently Asked Questions (FAQ)
Q1: What is the difference between primary and secondary magnesium ingots?
A: Primary ingots are produced directly from ore/brine. Secondary ingots are from recycled scrap. Primary has more controlled chemistry; secondary may have higher impurity levels but is more economical for some applications.
Q2: Why do ingot prices fluctuate so much?
A: Magnesium production is energy-intensive (14-16 MWh/ton), so energy prices directly impact costs. Chinese production (85% of global supply) is sensitive to environmental policies, power tariffs, and export regulations, causing volatility.
Q3: What are the payment terms typically available?
A: For new customers: 100% advance or LC. For established relationships: 50% advance, 50% before dispatch. Credit terms (7-30 days) available for large, regular customers with good credit history.
Q4: Can we get custom-sized ingots for our melting furnace?
A: Yes, Pentaphos offers ingots in various weights (5kg, 7.5kg, 10kg, 15kg) and can provide notched or T-bar ingots for easier handling and melting.
Q5: How do I verify the purity of magnesium ingots upon receipt?
A: We provide MTC with each batch. For additional assurance, you can:
- Send a sample to an independent lab (NML, BARC, or private labs)
- Use portable XRF for quick verification (less accurate for light elements)
- Perform simple acid dissolution and titration for approximate Mg%
Q6: What is the typical wastage/melting loss when using ingots?
A: With proper melting practice under flux cover, losses should be 2-5%. Higher losses indicate poor melting technique or contaminated charge material.
Q7: Are there any government regulations or licenses needed to buy magnesium ingots?
A: For industrial use, no special license is needed. However, large quantities may require storage approval from local fire department. Transport follows standard hazardous material rules (not Class 1 explosive).
Q8: What is the lead time for non-standard grades or large orders?
A: Standard grades: 3-7 days from our stock. Special grades: 15-30 days depending on sourcing. Container loads (20+ MT): 30-45 days if import required.
Q9: Do you offer cutting services for ingots?
A: Yes, we can provide ingots cut to specific weights or sizes for an additional charge, minimizing your handling and melting losses.
Q10: How does Pentaphos ensure consistent quality across batches?
A: We source from approved primary producers with established quality systems. Every inbound lot is verified against specifications. We maintain detailed traceability from producer to customer.
