What are the specifications and materials of the heating wire?

Usually when you buy a heating wire, you will say how much G you want. This G means gauge, which is the American standard. So, what is Awg?

1. WG for American Wire Gauge, which is a method of defining the diameter of the wire according to the number of holes that it will eventually pass through when it is cold drawn.

2. In addition to the American wire gauge Awg, there are also the British wire gauge swg, the Birmingham wire gauge bwg, and the national standard.

3. Commonly used, such as 24G corresponds to 0.51mm, 28G corresponds to 0.32mm, 30G corresponds to 0.25mm, 38G corresponds to 0.10mm, and 44G corresponds to 0.05mm. (24G to 44G, 0.5-0.05mm)

4. Generally speaking, single wire is generally used between 24G and 30G

5. Filaments such as Clapton, the main filament is generally between 26 and 32G, and the auxiliary filament is generally between 38 and 44G.

6. The corresponding relationship of its resistance is that the higher the Gauge, the smaller the diameter, and the greater the resistance (in unit length).

7. Commonly used materials such as Ni80 (Ni80201) correspond to the national brand name Cr20Ni80. In addition, Ni9010 is also popular now.

8. As for Kangsi Kanthal A1, it is actually a heating wire brand (Sweden), not a standard brand, generally refers to iron-chromium-aluminum heating wire, its main chemical composition contains Cr22/Al5.8, the corresponding national standard should be 0Cr25Al5 or 0Cr21Al6.

9. Others are 316L (ASME), corresponding to the national plate number S31603, which is 022Cr17Ni12Mo2. There are also Ni200, Ti, etc.
