Molybdenum wire standard and molybdenum wire grade
Release time:
2024-03-27
The standard and grade of molybdenum wire are mainly reflected in many aspects. The following is a specific introduction to these aspects:
Standard for 1. Molybdenum Wire
Dimensional tolerance standard: according to the national standard GB/T4182-2003 "molybdenum wire", the specification range of molybdenum wire is Φ0.02mm ~ Φ12.0mm.
Other standards: there are some other national standards related to molybdenum wire, such as GB/T4181-2006 "molybdenum wire", GB/T4182-2008 "molybdenum wire resistor", GB/T4184-2008 "molybdenum wire luminous electrode" and GB/"molybdenum wire vacuum corona discharge". These standards specify the technical requirements of the molybdenum wire itself, the technical indicators of the molybdenum wire resistor, the quality requirements of the molybdenum wire light-emitting electrode, and the application specifications of the molybdenum wire in the field of vacuum corona discharge.
2. molybdenum wire grade
Surface finish grade: the surface finish grade of molybdenum wire is divided into 1~5 grade, the smaller the number, the higher the surface finish. For example, a molybdenum wire with a surface finish of Class 1 is numbered Mo1a, and a molybdenum wire with a surface finish of Class 2 is numbered Mo1b.
Tensile strength grade: the tensile strength level of molybdenum wire is also divided into 1~5 grade, the larger the number, the higher the tensile strength. For example, a molybdenum wire with a tensile strength of grade 1 is numbered Mo1c, and a molybdenum wire with a tensile strength of grade 5 is numbered Mo5c.
In addition, according to the different chemical composition, molybdenum wire can also be divided into pure molybdenum wire, lanthanum molybdenum wire, yttrium molybdenum wire and silicon aluminum potassium molybdenum alloy wire, etc.; according to the different uses, can be divided into cutting molybdenum wire, spraying molybdenum wire, high temperature molybdenum wire, etc.; according to the different colors, can be divided into white molybdenum wire and black molybdenum wire.
In short, the standards and grades of molybdenum wire involve many aspects, covering dimensional tolerances, surface finish, tensile strength, and different classifications. These standards and grades help ensure the quality and performance of molybdenum wires to meet the needs of various application scenarios.
