Nichrome Heating Wire Cr20Ni80 Nickel Chrome Resistance Heat Element Wire Gadget

Nichrome wire Cr20Ni80 is a high resistance material with special purpose, widely used in industrial electric heating elements and high temperature resistors due to its excellent resistance performance and stability.

Material: 80% Ni 20% Chrome (Cr20Ni80)

Metal: Nickel-chromium alloy

Maximum Service Temperature: 1200℃

Melting Pointing: 1400℃

Application: Nichrome wire is widely used as resistance material in metallurgy, household appliances, machinery manufacturing and other heating elements and electrical industries. It can also be used for sculpture, wire weaving, decoration, crafts, beading, jewellery making, flower arranging, horticulture, fence restoration, wire shaping or packaging for amateur education.

Features:

High Temperature Resistance:Cr20Ni80 is capable of operating at temperatures up to 1200°C and has excellent high temperature oxidation and corrosion resistance. In high temperature environments, Cr20Ni80 has a small change in resistivity, which allows it to maintain precise control in applications with a wide range of temperatures.

Mechanical Properties: Cr20Ni80 has a high tensile strength, usually above 650 MPa, and an elongation between 15-25%, depending on the specific processing and heat treatment conditions. This alloy has good forming ability and fatigue resistance during processing.

Oxidation resistance: Cr20Ni80 has excellent oxidation resistance at high temperatures and is able to form a stable protective film of chromium oxide on the surface, effectively preventing further oxidation. This oxidation resistance makes Cr20Ni80 still maintain good performance after long time high temperature operation.

Corrosion resistance: Cr20Ni80 not only has good oxidation resistance under oxidising atmosphere, but also shows excellent corrosion resistance in some corrosive gases containing sulphur and chlorine.

Processing performance: Cr20Ni80 has good cold deformation plasticity and weldability, and will not produce brittle fracture in long-term use. This makes it suitable for use in the manufacture of electric heating elements of various shapes, such as wires, wires, strips and bars.

Magnetism: Cr20Ni80 is a non-magnetic material, which is an important property in some applications.
