The resistance of nichrome wire

Are you interested in the resistance of the nichrome wire? Supplier KMZ offers to buy at a economical price from the manufacturer of nichrome wire in stock. Supplier guaranteed prompt delivery of products at any address specified by the consumer.

Electrical properties

Resistivity of nichrome according to different sources, is 1.0…1.5 mcomm. The difference is explained by the different brands used nichrome alloys and different temperatures at which the research was conducted. Because nichrome has high heat resistance (will retain its operating characteristics up to temperatures of 1450…1460°C), it is used as electric heating elements for low and medium power. Due to the high cost of chromium, which is included in the composition of the alloy, nichrome heaters on the prevalence of inferior by Kopelev (resistivity Kopel is about 1.7 mcomm).


Produced two types of nichrome wire, the chemical composition, the first contains 80% Nickel and 20% chromium in the chemical composition of the second — 60% Nickel, 16% chromium and 24% iron.

Nichrome, which includes 18−29,% iron, is cheaper, has a higher specific resistance but it is less stable when heated, has a lower mechanical strength in tension and has a lower melting point. Be purchased at economical price from manufacturer nichrome wire provider offers KMZ. Supplier of guaranteed delivery of products anywhere in the application installed by the client.

Transcript of grades,

After the letter X indicates the percentage of chromium in the alloy, and after the letter N, the percentage of Nickel. Also available brands CR20NI80 nichrome-N, H15N60-H, which as an alloying element includes zirconium. GOST 12766−1-90 provides that in the name of the alloy can be given information about the technology of its smelting. In particular, the nichrome H15N60-CR20NI80 VI and-VI are made by technology of vacuum-induction remelting.
