Nickel alloys can be used as materials for electron tubes, precision alloys (magnetic alloys, precision resistance alloys, electric heating alloys, etc.), nickel-based high-temperature alloys, nickel-based corrosion-resistant alloys and shape memory alloys. Nickel alloys are widely used in sectors such as energy development, chemical industry, electronics, navigation, aviation and aerospace.

According to the introduction of Meng Quansheng, vice president of the China Petroleum and Chemical Industry Association, the construction of the four major standards systems includes: Energy Conservation and Emission Reduction Standard System. In September this year, the China Petroleum and Chemical Industry Association proposed 144 standards (repair) requirements, mainly related to energy-saving emission reduction products, clean production, water quotas, energy consumption quotas per unit and other standards; consumer product safety standards system. In the "Consumer Product Safety Standards System Framework" currently being revised by the National Standards Committee, the Association will make (amend) 41 standards for paints, adhesives, and dyes, and food safety standards. The association participated in the preparation of the "Eleventh Five-Year Plan for Development of Food Standardization" and proposed the establishment (repair) of 113 food additive standards; the standard method of testing methods. At present, the association has organized 46 declarations (repairs) of testing method standards, converted 32 REACH regulatory testing method standards, and developed 6 PFOS testing method standards.
It is understood that in recent years, China's chemical standardization has made great progress. The chemical industry currently has 59 standardization technical committees, including 50 national standardization technical committees and sub-technical committees; the chemical industry has a total of more than 4,000 standards, including nearly 2,000 national standards and 2,200 industry standards. Since 2005, the Petroleum and Chemical Industry Association has approved 1,718 chemical standard project plans issued by the competent department of standardization, including 1,107 national standard project plans and 611 industrial standard project plans. At the same time, it has also organized review and approval of 475 chemical industry standards.
The reporter learned from the 2007 National Conference on Chemical Standardization and Quality Inspection held in Xi'an on November 7-8 that chemical standardization work should focus on safety, health, and environmental protection in the near future. 4 major standards system construction; At the same time, will also study and formulate low-toxic high-efficiency pesticides, new varieties of chemical fertilizers, low pollution coatings basic standards, tires, rubber processing machinery safety and environmental protection standards.
