For example, if the wire is exposed to high humidity or acidic environments, it may corrode over time. Furthermore, if the wire is not properly protected from environmental elements, it may degrade, which can lead to corrosion. Therefore, it is important to use Nichrome 90 wire in appropriate environments and take proper care to protect it from corrosion.
