14 20 24 AWG 16SWG FeCrAl Alloy 0Cr13Al4 Electric Resistance Wire For Oven Heating
What is 0Cr19Al3 wire?
0Cr19Al3 wire is a type of iron-chromium-aluminum (FeCrAl) alloy wire with a specific composition. The composition of 0Cr19Al3 wire typically includes:
19% Chromium (Cr)
3% Aluminum (Al)
Iron (Fe) and trace amounts of other elements.
This alloy is known for its high resistance to oxidation and corrosion at elevated temperatures, making it suitable for various applications where heat resistance is required. 0Cr19Al3 wire is commonly used in heating elements, industrial furnaces, and electrical applications due to its excellent properties.
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.
Popularity in the Indian Market:
These FeCrAl alloys are popular in the Indian market due to their excellent properties such as high temperature resistance, oxidation resistance, and good mechanical strength.
They are commonly used in various applications including heating elements for industrial furnaces, ovens, electric heaters, and appliances.
The alloys are cost-effective compared to some other high-temperature alloys, making them a preferred choice in the Indian market for heating applications.
The alloys are readily available, easy to work with, and exhibit good performance in high-temperature environments, which contributes to their popularity in India.
Overall, the slight differences in composition between 0Cr19Al3 and 0Cr21Al4 result in variations in their properties, with both alloys being popular in the Indian market due to their reliability, cost-effectiveness, and suitability for a wide range of heating applications.
