✅ Product Description
Magnesium Lump is a high-purity, solid metallic form of magnesium typically used in metallurgical, chemical, and industrial applications. With purity grades ranging from 99% to ultra-high 99.999%, these silvery metallic lumps are known for their lightweight nature, strong reducing ability, and excellent thermal and electrical conductivity.
Processed through advanced melting and solidification methods, our Magnesium Lumps are suitable for alloying with aluminum, titanium, and rare earth metals, as well as for use in desulfurization, pyrotechnics, and semiconductor manufacturing. Their controlled lump size and low impurity levels make them ideal for precise industrial usage, ensuring stability and consistency during melting and reaction processes.

💬 FAQs (Frequently Asked Questions)
Q1: What's the difference between 99.9% and 99.999% purity magnesium?
A1: Higher purity magnesium is used in electronics and semiconductors where trace elements must be minimized. Lower purity is sufficient for alloying and metallurgy.
Q2: Can these be used in vacuum melting furnaces?
A2: Yes, especially high-purity and low-gas magnesium lumps are ideal for vacuum and EBM processes.
Q3: Is there a risk of oxidation during shipping?
A3: Our packaging is designed to prevent oxidation, with options for argon flushing or vacuum-sealing.
🧭 How to Choose the Product
For general alloying, 99.9% or 99.95% purity is typically sufficient
For electronic or high-purity needs, select 99.999% Mg
Consider lump size and packaging method based on your furnace or reactor type
📏 Product Standards
Conforms to ASTM, JIS, GB, EN, and BS standards
Additional certifications (ISO, REACH, RoHS) available based on customer requirements
🧪 Production & Quality Control
Each batch undergoes rigorous gas and impurity analysis using ICP-OES and gas chromatography. Controlled-atmosphere casting and cutting minimize oxidation and ensure homogeneity. Final inspection includes visual, dimensional, and chemical evaluations.
