Introduction:
0Cr23Al5 furnace wire is a high-temperature alloy material commonly
used in applications such as electric furnace heating elements,
thermocouples, and resistance wires. It is composed of elements
such as chromium (Cr) and aluminum (Al), of which the chromium
content accounts for about 23% and the aluminum content accounts
for about 5%. This furnace wire is known for its excellent
antioxidant properties and high temperature resistance.
0Cr23Al5 furnace wire has excellent high temperature resistance and
can operate stably for a long time in high temperature
environments. It has a high melting point (about 1500 degrees
Celsius) and can withstand extremely high operating temperatures.
In addition, the furnace wire has excellent anti-oxidation ability
and can resist oxidation, corrosion and deformation at high
temperatures, extending its service life.
The alloy furnace wire also has a low linear expansion coefficient,
allowing it to maintain good stability during thermal cycling. Its
thermal conductivity is high, which helps to conduct heat quickly
and improve heating efficiency. In addition, 0Cr23Al5 furnace wire
also has high tensile strength and yield strength, and can
withstand mechanical stress in high temperature environments.
