FAQs About This Product

Can KA1 Hive Coils Handle Continuous Operation?

Yes, KA1 Hive coils are built to handle continuous operation within their specified ratings. In addition to its high temperature resistance and structural integrity, FeCrAl A1 is also designed to maintain its structure and resistance over extended periods. In order to prevent overheating and damage to the coils, it is essential to ensure that they are operated within the recommended voltage and temperature limits, and always incorporate them into well-designed circuits that allow for proper heat dissipation.

Is There An Oxidation Risk With KA1 Hive Coils?

KA1 Hive coils, made from FeCrAl A1 wire, are engineered to be resistant to oxidation, especially at high temperatures, which is a common challenge in heating applications. KA1’s composition includes aluminum, chromium, and iron, which contribute to its ability to form a protective layer of aluminum oxide when heated. This layer acts as a barrier against further oxidation, enhancing the wire’s longevity and maintaining its electrical resistance over time. Therefore, under normal operating conditions, the risk of oxidation with KA1 Hive coils is minimal, making them suitable for projects where consistent performance and durability are essential.
