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.
