Introduction:

0Cr21Al6 furnace wire is a high-temperature alloy material, mainly composed of chromium (Cr) and aluminum (Al), with a chromium content of approximately 21% and an aluminum content of approximately 6%. This alloy has excellent oxidation resistance and high temperature resistance, and is often widely used in fields such as electric furnace heating elements and thermocouples.

0Cr21Al6 furnace wire has good chemical stability and is not prone to oxidation, corrosion and deformation in high temperature environments. It has a high melting point (about 1500 degrees Celsius) and can withstand long-term use under high temperature conditions. In addition, the grate bar has a low coefficient of linear expansion, allowing it to maintain good stability during thermal cycling.

The alloy material has high thermal conductivity, which helps to conduct heat quickly and improve heating efficiency. It also has high tensile strength and yield strength, and can withstand large mechanical stress at high temperatures. At the same time, the grate bar has a certain elongation rate, making it more flexible and easier to operate during processing and installation.
