FAQs About This Product

How Are Quad Coils Made?

Quad coils are made by wrapping four separate wires around a rod or mandrel to create a specific shape. These four wires are usually twisted together before they are wrapped around the rod, this creates the quad coil structure. The wires are then heated to a high temperature to anneal them, which makes them more pliable and easier to work with. The wires are then shaped into a specific coil structure, such as a clapton, fused clapton, or alien. The coils are then spaced and secured in place, usually with a small amount of wire or other material. The coils are then heated again to fuse the wire together, creating a strong, stable coil. This process is typically done by hand, although there are machines that can automate the process.

What Is KA1 Wire?

KA1 is a type of iron-chromium-aluminium (FeCrAl) alloy wire that is commonly used in the electronic cigarette industry as a heating element. It is known for its high resistance to oxidation and corrosion, as well as its ability to maintain its strength at high temperatures. The wire is made from a blend of iron, chromium, and aluminium and is typically red in colour. It has a high melting point of around 1425°C (2600°F) which is why customers have found it suitable for E-cig applications as well as other high temperature resistance applications. It is also widely used in industrial furnace, heating elements, and electrical resistance heating applications. It’s widely available in different gauges and can be easily worked with and bent to fit different builds.
