Tungsten and tungsten alloy materials have demonstrated excellent performance in various industrial fields, and their affordable prices have also increased demand for them year by year. Nuts and bolts are connecting materials used to fasten key components and are mainly made by powder metallurgy and high-temperature sintering processes. In mid-September, we safely sent the completed Tungsten Nuts And Bolts and Tungsten Heavy Alloy Bolt to Mexican customers via international express. At the same time, they spoke highly of the quality and processing of our products, and prepared the required professional certificates. They are also very complete and express their willingness to cooperate with us in the next stage.
