Molybdenum alloy extrusion

It is used to crush coarse as-cast grains and improve the processing performance of ingots. It can also be used to produce pipes, bars and profiles. In order to fully crush the as-cast grains, the extrusion ratio should not be less than 4, and the extrusion temperature is usually between 1100 and 1315°C. If products and intermediate products are obtained directly by extrusion, a larger extrusion ratio and higher extrusion temperature should be used. In order to extend the life of the mold and ensure the size and surface quality of the product, the mold should be coated with zirconium dioxide or aluminum oxide refractory, and lubricated with a glass lubricant during extrusion.
