Recently, the National Standards Committee issued the second batch of recommended national standards plan and the second batch of national standard sample research and copy plan project notices in 2021. Southwest Aluminum Melting and Casting Plant undertook the development of 9 single-point spectral standard samples and 3 spectral standard samples. Copy work.
The 9 spectral single-point standard sample development projects are aluminum alloy 6005A, 5083, 7B50, 5754, 7136, 8021, cast aluminum alloy 336Z.1, 355Z.2, 356Z.2, and the 3 spectral standard sample copy projects are pure Aluminum, aluminum alloy 2219, aluminum alloy 3003 (including Pb).
As a national non-ferrous metal standard sample research and development unit, Southwest Aluminum has been developing aluminum and magnesium alloy standard samples based on the production needs of the enterprise and the development trend of new materials in the non-ferrous industry for many years. After more than 30 years of development, it has gradually grown into the research and development of the non-ferrous industry. Leading enterprise of standard samples.
The project approved this time is a national standard sample developed by Southwest Aluminum based on the development trend of new aluminum alloy materials in the country and the gap in the national standard sample of aluminum alloy, combined with the actual development and production of Southwest Aluminum’s new material. Among them, they are used in aerospace, aviation, etc. Aluminum alloys in key areas also include civil aluminum alloys used in railway traffic, automobiles and ships, electromechanical equipment and other fields. The approval and issuance of the above aluminum alloy standard samples not only provides traceability for the chemical composition analysis of these aluminum alloy materials, but also facilitates the development of aluminum materials, and also provides technical support for accelerating the localization of my country’s high-tech aluminum alloy materials.
