GB/T 4193 Molybdenum Wire For Electric Light Source
1. Description Of GB/T 4193 Molybdenum Wire For Electric Light Source:
Electric light source molybdenum wire is mainly used as the filament holder and the core wire of the tungsten helix. Therefore, the molybdenum wire is required to have a uniform diameter, good straightness, high strength, and stable high temperature performance. It is also required that the molybdenum wire of the electric light source has a certain flexibility, and its elongation rate should reach 15%~25%.
Molybdenum wire is divided into different types of molybdenum wire according to the application range, including spray molybdenum wire, electric light source molybdenum wire, heating furnace molybdenum wire, electronic device molybdenum wire and electric spark cutting molybdenum wire, etc. The quality of molybdenum wire mainly depends on its chemical composition, mechanical properties, surface finish, unit weight and dimensional tolerance, etc., and the quality and performance requirements of different molybdenum wire products are somewhat different.
