A high-tech group limited company registered capital is 75 million yuan, established in May 1993, was initiated by the Original Metallurgical Department, the Steel Research Center, Metallurgy Automation Research and Design, Beijing University of Science and Technology and other ten research institutes And the university share, the enterprise group registered in the National Industry and Commerce Bureau. With the deepening of the national economic system reform and research institutes, in August 2002, Xinye Group was reorganized by the Ten Scientific Research Institutes, which was mainly based on the steel research terminal (now China Steel Research Technology Group Co., Ltd.). In the past five years, in the past five years, the company has transformed and upgrading, and it has actively developed energy-saving and environmental protection, new materials and new energy fields. It has developed fiber laser application technology, new carbide, tire regeneration Circular utilization and artificial sapphire long crystal and other technologies and occupy a leading position at home and abroad.
Metal powder introduction:
Metal powder refers to a metal particle group having a size of less than 1 mm. Including a single metal powder, alloy powder, and some difficult-melted powder having metal properties, is the main raw material of powder metallurgy. Metal mononas is generally silver white. When the metal is under certain conditions, it is black powder. Most metal powders are black.
Metal powder belongs to a loose substance, and its performance is comprehensively reflecting the properties of the metal itself and the characteristics of the characteristics of individual particles and the characteristics of the particle group. The performance of the metal powder is generally divided into chemical properties, physical properties and process performance. Chemical properties refer to metal content and impurity content. Physical properties include the average particle size and particle size distribution of the powder, the specific surface and true density of the powder, the shape of the particles, the surface morphology, and the internal microstructure. Process performance is a comprehensive performance, including the fluidity, loose density, resonance density, compression, formability and sintering dimension, and the like. In addition, the powder is also required to have other chemical and physical properties such as catalytic performance, electrochemical activity, corrosion resistance, electromagnetic properties, internal friction coefficients, and the like. The performance of the metal powder depends to a large extent on the production method of the powder and the process of making it. The basic properties of the powder can be determined by specific standard detection methods. There are many measuring methods for powder particle size and their distribution, generally screened (> 44 μm), settling analysis (0.5 to 100 μm), gas permeability, microscopy, and the like.
