AgCu28 powder is suitable for brazing, additive manufacturing, laser cladding and other application processes, with the characteristics of controllable particle size, low oxygen content, low impurity content, and batch stability. 1. Material standard The composition meets the requirements of GB/T 18762-2017 specification for precious metals and their alloys. 2. Controllable particle size According to different application processes, batch supply can be provided: -500 mesh, -300 mesh, -200 mesh, 15-53 μm, 45-105 μm, 75-150 μm and other particle size powders, can also be customized according to customer requirements. 3. Low oxygen content The core oxygen content control technology can control the oxygen content of powder according to the specific application technical requirements, and the minimum can be controlled below 200ppm. 4. Low impurity content The overall impurity content of the powder can be controlled below 0.01% (except gas content), and the purity ≥ 4N9. 5. Micromorphology The morphology of the powder is mainly spherical, which helps to ensure that the powder has good dispersion and fluidity. 6. Fluidity For 15-53μm powder for additive manufacturing, Hall fluidity ≤ 15s/50g.
