1. High accuracy with double grading: Good particle size distribution. The product size can be adjusted between 1-45μm accurately with the grading accuracy as ±0.5um.
2. Customized according to your requirements: Our factory can produce the products according to the different customers’ demanding and satisfy their different requirements for the specific powder.
3. Better quality control: Good sphericity , less impurity, 99.85% aluminum content in raw material with more than 98% active aluminum in finished product, produced and packed under the protection of nitrogen, auto-controlling in the producing process for quality assurance.
4. Good collecting rate: We produce the particle size as D50 between 0-75μm, the collecting rate of the powder that less than 10μm(D50≤10um) can be above 85%, which ensures the output of the ultra-fine aluminum powder;
Solar Cell Used Aluminum Powder
With the state of the art technology and hard work of R&D department, our company makes full use of the advanced production technology - nitrogen atomized protection method, to produce the product with the technical specifications in full compliance with national military standard GJB1738-93 and the American military standard MIL-DTL-512B.. It combines the centrifugal grading and whirlwind grading classification to adjust accurately the products particle sizes between 1-45 micron.
