CX600 Nickel Chromium Iron Heating Wire Used In Chemical And Heat Treatment Industries
CX600 is a nickel-chromium-iron alloy that provides superior resistance to oxidation at temperatures up to 1000 °C. It also provides good resistance against stress corrosion cracking in chloride environments. This alloy also offers good mechanical properties and workability. Owing to its good corrosion resistance properties at high temperatures, it is widely used in chemical and heat treatment industries. Since it maintains good mechanical properties at high temperatures, it is also used in the aeronautical industry to manufacture various aircraft and engine components.
CX601 is a nickel-chromium-iron alloy with a substantial chromium content that provides resistance to many corrosive media and high temperature environments. Oxidation resistance is further enhanced by addition of aluminum.

Some key features of CX600 alloy include:
The combination of Nickel, Chromium, and Iron provides CX600 with relatively high electrical resistivity, making it ideal for use as a heating element. The wire produces heat efficiently when an electric current is passed through it, which is crucial in electric heating applications.
CX600 can withstand high operating temperatures (up to around 1100°C or 2012°F), making it suitable for use in high-temperature environments like ovens, furnaces, toasters, and industrial heating elements.
The Chromium content in the alloy provides excellent oxidation resistance, allowing CX600 wire to retain its strength and resist degradation at high temperatures. This is especially important for heating elements that need to maintain their structural integrity over extended use.
CX600 has good mechanical strength, allowing it to be drawn into thin wires while maintaining durability. This strength is essential in preventing breakage under mechanical stress or when the wire is coiled for use in heating elements.
The combination of high resistance to oxidation, corrosion, and mechanical stress gives CX600 an extended lifespan in heating applications, even under constant high temperatures.
