Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 4182-2003 "molybdenum wire". This standard and GB/T 4182-2003 compared to the main changes are as follows.
--- increased the definition of molybdenum wire and white molybdenum wire;
--- increased MoLa, MoY and MoK grades and requirements;
--- increase the line cutting, spraying molybdenum wire at room temperature mechanical performance requirements;
--- increase the diameter of 1800μm ~ 5000μm size requirements;
--- increase the diameter of more than 400μm minimum length requirements;
--- increase the thermal brittleness performance requirements and test methods;
--- increase the shelf life of the storage requirements.
This standard is proposed by China Nonferrous Metals Industry Association.
This standard is owned by the National Committee for the Standardization of Nonferrous Metals (SAC/TC243).
The standard drafting unit. Xiamen Honglu tungsten and molybdenum Industry Co., Ltd., Jinduicheng Molybdenum Co., Ltd., Jinduicheng Molybdenum Industry (Shandong)
Co., Ltd., Zigong Carbide Co., Ltd., Beijing Tianlong Tungsten Molybdenum Technology Co., Ltd., Beijing Mining and Metallurgy Research Institute.
The main drafters of this standard. Peng Fusheng, Li Fengjin, Pan Xiaofeng, Tang Jin, Wu Jianhong, Li Shiwei, Huang Lifeng, Dong Ping, Su Guoping, Zhong Ming,
Wang Luyan, Zhang Shengjie.
This standard replaced the previous version of the standard release.

3 terms and definitions
The following terms and definitions apply to this document.
3.1
After the drawing on the reel or around the wire into the coil of molybdenum metal wire, or diameter less than 0.40mm small length of molybdenum material.
3.2
Through the electrolysis, chemical treatment, annealing, etc. to remove the surface of the graphite coating, the surface was silver or silver-white molybdenum wire.
4 Classification and marking
Classification and classification of molybdenum wire
Molybdenum wire can be divided into three grades according to the diameter tolerance requirements, molybdenum wire processing state can include drawing, straightening, annealing, electrolysis and chemical
Reason. The molybdenum wire grading and classification marking method is shown in Table 1.
