High-Temperature Stability & Mechanical Strength FeCrAl Alloy
OhmAlloy145 0Cr27Al7Mo2 Heating Resistance Wire
General Introduction:
0Cr27Al7Mo2 is another type of electrical resistance heating alloy
wire. It is an iron-chromium-aluminum alloy with the addition of
molybdenum in its composition. The numbers in the name represent
the approximate composition of the alloy (0% iron, 27% chromium, 7%
aluminum, 2% molybdenum).
This alloy wire is known for its high-temperature resistance,
oxidation resistance, and corrosion resistance, similar to other
iron-chromium-aluminum alloys. The addition of molybdenum can
enhance certain properties of the alloy, such as improved
mechanical strength and stability at high temperatures.
0Cr27Al7Mo2 wire is commonly used in applications where
high-temperature heating is required, such as industrial furnaces,
electric ovens, and heating elements in various industrial
processes. Its properties make it suitable for environments where
the wire is exposed to heat and potentially corrosive elements,
ensuring reliable performance and durability under demanding
conditions.
What is the feature of 0Cr27Al7Mo2 wires against other FeCrAl type
wire?
0Cr27Al7Mo2 wire, as compared to other FeCrAl type wires, offers
some distinct features and advantages due to the addition of
molybdenum in its composition. Here are some key features of
0Cr27Al7Mo2 wire compared to other FeCrAl type wires:
1. Improved High-Temperature Stability: The presence of molybdenum in 0Cr27Al7Mo2 wire can enhance its
high-temperature stability and mechanical strength compared to
traditional FeCrAl wires. This can result in improved performance
and durability at elevated temperatures.
2. Enhanced Corrosion Resistance: The addition of molybdenum in 0Cr27Al7Mo2 wire can provide better
corrosion resistance, especially in more aggressive environments.
This can extend the lifespan of the wire and maintain its
performance in corrosive conditions.
3. Increased Oxidation Resistance: The molybdenum content in 0Cr27Al7Mo2 wire may contribute to
enhanced oxidation resistance, making it more resistant to
oxidation at high temperatures compared to some other FeCrAl wires.
4. Mechanical Strength: The presence of molybdenum can improve the mechanical strength of
0Cr27Al7Mo2 wire, making it more robust and durable in applications
where mechanical stress is a concern.
5. Potential Cost: Due to the additional alloying element molybdenum, 0Cr27Al7Mo2
wire may be slightly more expensive compared to traditional FeCrAl
wires. However, the enhanced properties it offers may justify the
cost in certain applications where superior performance is
required.
Overall, 0Cr27Al7Mo2 wire stands out from other FeCrAl type wires
due to its improved high-temperature stability, corrosion
resistance, oxidation resistance, mechanical strength, and
potential cost considerations. These features make it a suitable
choice for applications that demand superior performance under
challenging conditions.
