In the realm of industrial heating elements, two materials that often find their way into critical applications are Incoloy 800 vs copper heating elements. Both materials possess unique properties that make them suitable for specific heating requirements. Understanding the differences between these two materials is crucial for ensuring the right choice is made for a given application. In this blog post, let’s take a closer look at the differences between the Incoloy 800 and copper heating elements.
Incoloy 800 vs Copper Heating Elements – What’s the Difference?
Incoloy 925 (N08925) alloy is a nickel base alloy containing molybdenum and copper with excellent hot and cold work properties.
Incoloy 800/800H/800HT the chemical composition of these three are very similar, so all have a very good resistance to reduction, oxidation, nitriding medium corrosion and resistance to redox alternating medium corrosion performance, and in the long term application of high temperature has a high metallurgical stability.
Incoloy 800 vs Copper Heating Elements – 1. Incoloy 800: An Overview
Incoloy 800 is a nickel-iron-chromium alloy that offers exceptional resistance to corrosion and oxidation at elevated temperatures. This material was developed specifically to handle high-temperature applications without sacrificing its mechanical properties. Its composition, which includes nickel, chromium, and iron, among other elements, gives it high ductility and toughness even under severe thermal conditions.
One of the key features of Incoloy 800 is its ability to maintain its mechanical properties at temperatures up to 1300°F (704°C). This allows it to be used in high-temperature heating elements without experiencing significant degradation in performance. Additionally, its resistance to corrosion in oxidizing atmospheres makes it suitable for use in environments where other materials would quickly fail.
Incoloy 800 vs Copper Heating Elements – 2. Copper Heating Elements: An Overview
Copper, on the other hand, is a widely used material for heating elements due to its excellent conductivity. Copper’s high electrical conductivity allows it to transfer heat efficiently, making it a popular choice for applications that require rapid heating. Additionally, copper is relatively inexpensive and easy to work with, further adding to its popularity.
However, copper’s use in high-temperature applications is limited by its relatively low melting point of 1981°F (1083°C). Above this temperature, copper begins to lose its structural integrity, making it unsuitable for sustained use in extreme thermal conditions. Additionally, copper’s susceptibility to oxidation at higher temperatures can lead to corrosion and premature failure.
Comparing Incoloy 800 vs Copper Heating Elements
When comparing Incoloy 800 and copper heating elements, several key differences become apparent:
- Temperature Resistance: Incoloy 800 can maintain its mechanical properties at temperatures well above those at which copper would melt. This makes Incoloy 800 the preferred choice for high-temperature applications.
- Corrosion Resistance: Incoloy 800’s resistance to corrosion in oxidizing atmospheres is superior to copper’s. This allows it to withstand exposure to corrosive environments without premature failure.
- Cost: Copper is generally more cost-effective than Incoloy 800 due to its abundance and ease of processing. However, the longer lifespan and superior performance of Incoloy 800 often justify its higher initial cost.
- Heat Transfer Efficiency: Copper’s high conductivity makes it more efficient at transferring heat than Incoloy 800. This can be advantageous in applications that require rapid heating.

In summary, the choice between Incoloy 800 vs copper heating elements depends on the specific requirements of the application. For high-temperature applications or those that involve exposure to corrosive environments, Incoloy 800 offers superior performance. On the other hand, copper’s cost-effectiveness and excellent heat transfer properties make it a suitable choice for lower-temperature applications that require rapid heating.
