Alumina Zirconia Blast Media
ZA25 and ZA40 Zirconia fused alumina are manufactured using an advanced melting process and have a service life that is 3 to 6 times longer than traditional sandblasting media, which can significantly reduce the need for particle embedding and waste disposal. ZA25 has stronger cutting force and is suitable for heavy cleaning, scale removal, and high-pressure sandblasting equipment; ZA40 has greater toughness and durability, and is suitable for high-precision processing and applications with high surface finish requirements, especially for low-pressure sandblasting equipment.
