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.
