Nickel-Chromium-Iron Alloys(ALLOY 600 series)resistance wire heating wire
Product Description
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. CX601is 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.
| Applications |
CX600 is usually selected for applications which require resistance to corrosion like wire mesh, filters, fasteners for chemical industry, high temperature applications such as industrial furnaces.
CX601 is used in many different applications like thermal processing, chemical processing, pollution control, aerospace, and power generation.
