Corrosion Resistance
We've discussed the differences between copper and invar when it comes to thermal conductivity, but let's now take a look at how these two materials compare when it comes to corrosion resistance.
When looking at corrosion resistance, there are several factors that come into play: 1) strength of the material; 2) exposure to environmental elements; 3) presence of protective coatings; and 4) maintenance requirements. Here's a closer look at how copper and invar stack up in each category:
- Strength: Copper is known for its excellent malleability, while invar is much harder and more rigid than copper. As a result, copper offers greater protection against corrosion due to its ability to withstand extreme temperatures.
- Exposure: Copper can corrode quickly if exposed to certain environmental elements such as salt water or chlorine-based chemicals, whereas invar is highly resistant to these types of corrosive agents.
- Protective Coatings: Both materials require some type of protective coating in order to protect them from corrosion over time, but copper will need more frequent maintenance than invar due to its tendency towards oxidation when exposed to air or water-based solutions.
- Maintenance Requirements: Invar requires less maintenance than copper since it does not oxidize easily and is not affected by many chemical solutions--so you can expect longer life out of an invar product compared with copper products that will require ongoing upkeep or replacement over time due to wear and tear on the surface coating layer(s).
Overall, both materials have their advantages and disadvantages when it comes to corrosion resistance. But, thanks to its superior strength coupled with low maintenance requirements, invar has become an increasingly popular choice for applications that require long-term stability and durability in harsh environments where other metals may deteriorate rapidly over time.
