High-Quality Uncoated Aluminum Powder from China Suppliers | Spherical Aluminum Pigment Powder Factory

TJWX, a leading factory in China, boasts over twenty years of experience in producing high-quality spherical aluminum powder. Our atomized spherical aluminum powder, characterized by its silver-gray appearance, is derived from aluminum ingots with a purity of over 99.8%. This process involves melting the aluminum in a furnace at high temperature and pressure, resulting in a highly active product with a significant specific surface area, After atomization, our spherical aluminum powder develops a thick layer of alumina on its surface, which protects the active aluminum inside, ensuring optimal performance. As a trusted supplier in the industry, we prioritize the safe and stable production of our products. For more information, please reach out to us at info@hnjwx.com

Product Details

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.
