FAQs About This Product

What Is A KA1 Fused Coil?

KA1 Fused Coil is a pre-made, precision-crafted wire component that is used in numerous heating applications. The alloy is made from KA1, a type of iron-chromium-aluminum (FeCrAl) with high heat and oxidation resistance. As the name implies, this coil is constructed from two strands of 28 AWG wire that have been bonded together by wrapping a thinner 32 AWG wire around them. Using this design allows the coil to heat quickly and evenly, offering a resistance of 0.45 ohms, which is ideal for applications that require a controlled and stable temperature. Since they come premade and ready to install, these coils are popular due to their durability, performance, and ease of use.

How Quickly Do KA1 Fused Coils Heat Up?

KA1 Fused Coils are designed to heat up rapidly due to their construction and the materials used. The dual-core of 28 AWG wires wrapped with a 32 AWG wire allows for a quick ramp-up time, meaning the coil reaches the desired temperature swiftly once power is applied. The precise heat-up time can vary depending on the power source and the specific application in which the coil is used. However, users can generally expect a prompt response and consistent performance from these coils, making them suitable for uses that require a quick and reliable heat source.
