High-Quality Uncoated Aluminum Powder from China Suppliers - Spherical Aluminum Pigment Factory
It was collected by sealing atomization, classification, blending and sieving process. During the production process, it is controlled by strict controlling method to keep the particle size distribution and consistent appearance; The particle size of spherical aluminum powder used for aluminum powder is narrow, which ensures good reflectivity, good brightness and hiding power.

Frequently Asked Questions (FAQ)
Q1 What is the active aluminum content of this spherical aluminum powder?
Depending on the grade and particle size (JWX models from 1~2µm up to >32µm), the active aluminum content is strictly maintained at ≥98% to ≥99%, with low impurity content (Fe ≤ 0.2%, Si ≤ 0.2%, Cu ≤ 0.015%, and H2O ≤ 0.1%).
Q2 What packaging options and container capacities are available?
The material is supplied in 25Kg/Iron drums, 160Kg/Iron drums, or 200Kg/Iron drums with pallets. For standard 20FCL shipping, load volumes can be configured at 12.8 tons, 16 tons, or 18 tons.
Q3 What precautions should be taken when storing and handling aluminum powder?
Strictly avoid contact with water, acids, alkalis, and halogens. Operations must avoid dust spraying into the air and implement proper anti-static grounding measures to ensure safe handling.
Q4 How is product quality and particle distribution controlled during production?
Production is governed under GB/T19001:2016 / ISO9001:2015 quality control systems. Testing includes ICP for raw aluminum ingot impurities, laser diffraction testing machines for particle size (D50), moisture testers for water content, and dedicated oxygen content machines.
Q5 What are the typical end-use applications and industries for this powder?
It is primarily used to produce non-leafing and leafing aluminum pastes. Target application fields include industrial paints (automobile, marine, anti-corrosion), printing inks (packaging coatings), plastics (toys, electrical parts), cosmetics (nail oil, eye shadow), and architectural paints.
Q6 What is the annual production capacity and expected delivery lead time?
Our annual production capacity is 8,000 tons. The standard delivery time is 2~3 months, which includes Export License (EL) application processing and full quality inspection.
