Material Introduction

Refractory metals have a melting point higher than 1,650°C, and are irreplaceable basic materials and strategic resources for modern industry. At the beginning of the founding of the People's Republic of China, advanced materials were urgently needed by the country at that time, but refractory metal materials were almost in a blank state. In 1958, we began to explore materials such as tungsten, molybdenum, tantalum, niobium, and rhenium. We found that "refractory" metals are also "difficult to use" metals; they are "difficult" right the way from material forming to deformation processing! After several generations of arduous efforts, we have carried out a lot of pioneering work in materials, technology, equipment and other aspects. We invented China's first "hot and cold isostatic press", the first "2000-2300 ℃ large-scale sintering furnace for tungsten heating elements through hydrogen", the first "vacuum one-pass hydrogen infiltration furnace", and many others. We also invented tungsten-rhenium thermocouple wire and tungsten-infiltrated copper material. In the long course of development in the field of refractory metals, we have led the industry and contributed our strength. Due to their excellent properties of "high temperature resistance, ablation resistance, and creep resistance", our materials solve a variety of problems in national strategic fields such as aerospace, electronic power, and equipment manufacturing. As the national economy develops, our materials have become increasingly widely used in emerging industries such as nuclear energy, nuclear medicine, LEDs, semiconductors, large scale integrated circuits, and new energy vehicles, due to their excellent properties such as "radiation resistance, outstanding shielding performance, low thermal expansion rate, high thermal conductivity, and good electrical conductivity". To meet market demand, our materials closely link the functional integration design of materials with users, and have formed six major material systems, covering "tungsten and tungsten alloysa", "molybdenum and molybdenum alloys", "rhenium and rhenium alloys", "tantalum niobium and its alloys", "ceramic products" and "composite materials", to provide advanced refractory material design and manufacturing solutions.
