14 20 24 AWG 16SWG FeCrAl Alloy 0Cr13Al4 Electric Resistance Wire For Oven Heating
What is 0Cr19Al3 wire?
0Cr19Al3 is an iron-chromium-aluminum alloy wire. It is a type of resistance heating alloy that is commonly used for heating elements in various electrical appliances and industrial furnaces. The "0Cr19Al3" designation indicates the composition of the alloy, with 0 representing the iron content, Cr representing chromium, and Al representing aluminum. The numbers in the designation provide the approximate percentage composition of each element in the alloy.
The 0Cr19Al3 wire exhibits high resistivity and good oxidation resistance at elevated temperatures, making it suitable for applications where consistent and reliable heat generation is required. This type of alloy is known for its durability and performance in high-temperature environments, which is essential for heating elements in ovens, electric stoves, industrial furnaces, and other heating applications.
What is main applications of 0Cr19Al3 wire?
The main application of 0Cr19Al3 is in the manufacturing of heating elements for various electrical appliances and industrial furnaces. This iron-chromium-aluminum alloy wire is commonly used in the following applications:
1. Electrical Appliances: 0Cr19Al3 wire is used in the production of heating elements for electric ovens, toasters, electric stoves, and other household appliances where reliable and efficient heat generation is required.
2. Industrial Furnaces: The alloy is utilized in the construction of industrial furnaces, kilns, and heating systems where resistance to high temperatures and consistent heat output are essential for industrial processes.
3. Resistance Heating: It is employed in applications that require resistance heating, such as in heat treatment processes, industrial drying equipment, and other thermal processing systems.
Overall, the 0Cr19Al3 alloy is valued for its high resistivity and good oxidation resistance at elevated temperatures, making it well-suited for a wide range of heating applications in both household and industrial settings.
What is the difference between 0cr19al3 and 0cr21al4?
The main difference between 0Cr19Al3 and 0Cr21Al4 lies in their composition, specifically in the percentage of Chromium (Cr) and Aluminum (Al) present in the alloy. Here are the key distinctions:
Composition:
0Cr19Al3: Contains 19% Chromium and 3% Aluminum.
0Cr21Al4: Contains 21% Chromium and 4% Aluminum.
Properties:
The higher Chromium content in 0Cr21Al4 provides better oxidation
resistance compared to 0Cr19Al3.
0Cr21Al4 may offer slightly higher temperature resistance due to
its composition.
