CX1201 The Durable and Flexible Alloy Wire Strand for Household Heaters and Electric Pipes
19-Strand Nickel-Chrome Wire refers to a specific type of wire made from a combination of Nickel (Ni) and Chromium (Cr), designed for various high-performance applications. The "19-strand" designation indicates that the wire is made up of 19 individual strands, which are twisted or braided together to form a single wire.
19-Strand Nickel-Chrome Wire is a high-performance material used primarily for its resistive heating capabilities in various industrial and household applications. The combination of high electrical resistivity, thermal stability, corrosion resistance, and flexibility makes it ideal for environments that demand reliable, long-lasting performance at high temperatures.

Some key features of 19 Strands Alloy Nickel Chrome Wire include:
Typically consists of around 80% Nickel (Ni) and 20% Chromium (Cr), though the exact composition can vary depending on the specific alloy used (such as NiCr 80/20, or other similar variants).
Nickel offers excellent resistance to oxidation, corrosion, and high-temperature environments.
Chromium enhances the alloy's resistance to high temperatures and improves the material's durability and tensile strength.
High Resistivity: The wire has a relatively high electrical resistivity, which is why it is commonly used in heating elements (e.g., electric ovens, toasters, industrial furnaces) where it is heated by electrical current.
Stable Resistance: The resistance of Nickel-Chrome alloys remains stable over a wide temperature range, making them ideal for use in resistive heating applications.
Good Tensile Strength: The 19-strand configuration gives the wire higher flexibility and strength compared to single-strand wire, making it durable and resistant to mechanical stresses.
Enhanced Flexibility: The multiple strands in the wire improve its flexibility, which is beneficial when the wire needs to be coiled, bent, or twisted in different applications.
The alloy maintains its structural integrity and resistance properties at elevated temperatures, often exceeding 1000°C (1832°F), depending on the specific alloy variant.
It is widely used in high-temperature environments where other materials would degrade.
Nickel-chromium alloys are resistant to oxidation, corrosion, and scaling at high temperatures, making them suitable for long-term use in harsh environments.
Applications:
Used in electric heaters, furnaces, toasters, and heat guns due to its ability to generate heat efficiently when an electrical current is passed through it.
Employed in precision resistors, where stable and consistent resistance is needed.
Often used in shunt resistors for current sensing applications.
Used in industrial equipment, laboratory heating coils, and other devices where precise temperature control and high heat resistance are required.
Occasionally used as part of the thermocouple wire for high-temperature measurements, though other alloys like Platinum are more commonly used for thermocouples.
Due to its high strength, corrosion resistance, and thermal stability, it is also found in certain aerospace and automotive applications requiring high-performance materials.
