Nichrome (NiCr, nickel-chrome, chrome-nickel, etc.) is any of variousalloys of nickel, nichrome and often iron (and possibly other elements). The most common usage is as resistance wire, although they are also used in some dental restoration (fillings) and in a few other applications.
Ni70Cr30 rod is a high-temperature alloy material composed of 70% nickel and 20% chromium. It offers a range of functional advantages, as described below:
1/High Temperature Stability: The Ni70Cr30 rod exhibits excellent high-temperature stability, allowing it to withstand extreme temperature conditions. It can operate at temperatures as high as 1200 degrees Celsius without significant deformation or oxidation, making it highly suitable for use in high-temperature environments.
2/Corrosion Resistance: This alloy rod demonstrates outstanding corrosion resistance, effectively resisting oxidation, sulfidation, and other corrosive media. This property makes the Ni70Cr30 rod widely applicable in industries such as chemical manufacturing, petroleum refining, and other environments that require corrosion-resistant materials.
3/Mechanical Strength: The Ni70Cr30 rod possesses good mechanical strength, enabling it to withstand high stress and pressure. Even at elevated temperatures, it maintains high hardness and strength, making it well-suited for applications that require load-bearing capabilities, such as heating elements, furnace components, and furnace tubes.
4/Thermal Conductivity: The alloy rod exhibits excellent thermal conductivity, efficiently transferring heat. This characteristic makes it highly useful in heating and thermal management applications, including heating elements, electric furnaces, electric heaters, and heat exchangers.
5/Oxidation Resistance: The Ni70Cr30 rod demonstrates outstanding oxidation resistance, forming a stable oxide layer at high temperatures to protect its surface from oxidation damage. This attribute contributes to its longevity and reliability in high-temperature heating and elevated temperature environments.
