The national standard of "High Entropy Alloy Powder for Additive Manufacturing" led by Jiangsu Wellary New Material Technology Co., Ltd. of Xukuang Group has been officially implemented recently.
It is reported that this standard fills the gap in the national standard system of high-entropy alloy powder for additive manufacturing, so that the high-entropy alloy powder for additive manufacturing in mainland China has technical indicators, and the standard can be followed and documented, and it will actively promote the progress of high-entropy alloy powder production, process and technical standards, and better serve the high-quality development of industrial applications such as aero engines and marine engineering.
As a state-level high-tech enterprise cultivated by Xuzhou Mining Group, Jiangsu Willary New Material Technology Co., Ltd. is a rising "star" among the state-owned science and technology enterprises in the province.
As a test field for the emerging industries of Xuzhou Mining Group, the company was selected as a "Science and Technology Reform Demonstration Enterprise" for the reform of state-owned enterprises of the State Council, and was rated as a national-level specialized and special new "Little Giant" enterprise. It has created "three uniques" in the field of metal powders: the only enterprise in the country that produces aluminum alloy powder with Hall flow velocity in atmospheric environment, the only enterprise in China that has the technology to stably produce CuCrZr powder, and the only enterprise in the country that has the production technology of multi-system high-entropy alloy. In 2022, the company successfully held a mixed-ownership reform investment contract and signed the "first order of mixed-ownership reform" in the province that year, taking a solid step towards the listing of the Science and Technology Innovation Board.
In 2023, the company will complete two rounds of financing of 350 million yuan A and B, better serve the strategy of manufacturing power, and strive to build a model for the reform of state-owned science and technology enterprises and a pioneer in independent innovation.
The "new standard" drives development
Compared with traditional alloys, high-entropy alloys have excellent comprehensive properties such as high strength, high hardness, corrosion resistance, wear resistance, high temperature resistance, radiation resistance and soft magnetism, and have a wide range of applications, especially in the application of complex metal parts in the engine industry, hard tool industry, marine engineering, nuclear industry and other industrial fields.
The national standard "high-entropy alloy powder for additive manufacturing" is applicable to high-entropy alloy powder for additive manufacturing prepared by gas atomization, plasma rotating electrode and other processes, the standard stipulates the chemical composition, particle size, loose density, tap density, fluidity and other key performance testing indicators and process performance parameters of the powder, covering the grade and classification of powder, test methods, inspection rules and signs, packaging, transportation, storage, accompanying documents and order forms, etc.
The relevant person in charge of Jiangsu Wellary New Material Technology Co., Ltd. introduced: "The formulation of the national standard will guide the research and development of high-entropy alloys to be carried out in an orderly manner, strengthen the technical understanding and communication between supply and demand, guide and standardize the production and sales of the product, and meet the different needs of relevant fields in the market." ”
"Hard power" leads the way
As a national high-tech enterprise cultivated by Xuzhou Mining Group, Jiangsu Wellary New Material Technology Co., Ltd. resolutely shoulders the mission and responsibility of state-owned enterprises, takes the initiative to undertake national scientific research tasks, and actively participates in the formulation of national standards.
Up to now, the company has a total of 2 technical appraisals to the international leading level, 2 national projects are progressing smoothly, 5 materials research and development has made new breakthroughs, the establishment of 4 company-level research and development platforms, self-built and co-built 2 provincial research and development platforms, the country's first self-designed single-furnace charging capacity of 500kg VIGA equipment has been put into production, a total of 144 authorized patents, including 56 invention patents, led or participated in the drafting of 22 national standards, 13 have been released. In 2023, it will obtain 13 national brand honorary qualifications such as "China's Good Technology" and "China's Top Ten Advances in Nonferrous Metals", and win 11 science and technology awards at or above the provincial level.
The "Little Giant" is in the spotlight
Since last year, the technical strength and market prospects of Jiangsu Wellary New Material Technology Co., Ltd. have won wide attention and capital favor.
On September 25, 2023, Jiangsu Willary New Material Technology Co., Ltd.'s vivid practice of promoting the R&D and manufacturing of metal powders was reported by the leading column of CCTV's financial channel "Economic Information Network".
From November 7th to 10th, 2023, Jiangsu Willary New Material Technology Co., Ltd., as the world's leading provider of metal additive manufacturing solutions, brought a variety of metal powder products and application solutions to the Formnext-Frankfurt International Precision Forming and 3D Printing Manufacturing Exhibition, showing the cutting-edge products and scientific and technological strength of the century-old Xu Mine to global users.
Since entering 2024, the company's achievements have been quite impressive, with production, consumption, and research going hand in hand. In terms of R&D, breakthroughs have been made in the mechanical properties of high-temperature alloy powder GH4099, and the first domestic top-pouring gas atomization powder furnace has a stable batch production capacity.
"With firm confidence, solid measures and pragmatic style, we will find the correct positioning, shoulder heavy burdens and contribute to the overall development of the group company and the cultivation of new quality productivity. The head of the company said with confidence.
