Product Characteristic
1. Regular particle shape
Production technique of atomization method taken by us decides that our magnesium powder is solid and spherical, and particle shape is regular.
2. High spherical rate
Atomized aluminum magnesium alloy powder has high spherical rate, the reaction activity of each point on the surface of the particle is similar or same, with stable reaction. At the same time, sphere surface lowers the friction sensitivity of powder, compared with milling magnesium powder, it is safer from the aspects of handling transportation and production blending.
3. Large apparent density
The more the apparent density is, the higher the upper limit of explosive payload is, the more the active ingredient content participating in reaction is, and the wide the adjustable range of the explosive payload is.
4. Good liquidity
Even particle shape and high spherical rate decide its good liquidity, the better the liquidity is, the more even the blending property with other medicament is, the more stable the reaction and the better is compatibility is.
5. High active Mg +Al content
The more the active Mg+Al content, the more the active ingredient content participating in reaction is, and the better the controllability of main reaction is, which not only can save cost, but also can reduce side reaction.

Frequently Asked Questions (FAQ)
What are the main particle size distributions and alloy ratios available for this powder?
The particle size distribution is within 30-1000 meshes (15um—500um), and tailor-made granulation is available. The alloy matching range is mainly Al-Mg 5:5, Al-Mg 8:2, Al-Mg 6:4, and Al-Mg 4:6.
Why is atomized aluminum magnesium alloy powder safer than mechanical milling powder?
Due to its high spherical rate (≥95%), the spherical surface lowers the friction sensitivity of the powder. This makes it safer than mechanical milling powder during handling, transportation, and production blending.
How does the apparent density affect the performance of the powder?
A larger apparent density (≥1.2 g·cm⁻³ compared to 0.826 g·cm⁻³ of mechanical powder) raises the upper limit of the explosive payload, increases the active ingredients participating in the reaction, and widens the adjustable range of the explosive payload.
What advantages does the high active Mg + Al content provide?
The higher active Mg + Al content (99.25% in atomized powder compared to 90.58% in mechanical powder) means more active ingredients participate in the reaction, leading to better controllability of the main reaction, reduced side reactions, and cost savings.
What is the difference in moisture absorption and impurity levels between atomized and mechanical powder?
Atomized powder has a significantly lower moisture absorption rate of 0.01% compared to 0.09% of mechanical powder. Additionally, the impurity content (such as Fe, Cu, Cr, and Zn) is substantially lower in the atomized powder, guaranteeing higher purity.
