Demagnetization is the process of removing magnetism from an object. Magnetism can stick around in steel and cast iron pieces for various reasons. Regardless of its origin, this residual magnetism (aka residual magnetization) can be a real pain, so it’s worth knowing how to get rid of it.
Welding becomes a nightmare: The welding arc goes wherever it pleases. You want to weld here, but you’re actually welding there.
Surface treatments go south: Nickel and chrome plating get messed up. You get deposits, and the finish looks like a amateur job.
Production grinds to a halt: Magnetized parts attract chips and stick together. Instead of nice, clean chips that flow away smoothly, you get a sticky mess.
Parts become unsellable: Customers might reject them for non-compliance. Nobody wants them because they cause issues in subsequent processing.
Disclaimer: We’re only talking about demagnetizing steel and cast iron. Want to demagnetize something else? We can’t (yet) help you.
Tubes and bars: Demagnetization is crucial here
Industrial components: gears, shafts, wheels, screws, molds
Steel forming and punching dies: Magnetism makes scrap stick to dies, preventing precise and smooth operation
Just call us – we’ll help you figure it out.
There are various demagnetization technologies, all aimed at removing residual magnetization.
Here’s the fancy explanation: Electrical systems create magnetic induction that interacts with internal magnetic domains in ferromagnetic materials, shifting Wells domain boundaries to achieve finer magnetic grain texture within the metal matrix; simultaneous randomization of magnetic vector directions makes the vector sum of all magnetic field vectors approach zero.
Simple, right? Yeah, no. That’s why we’re here – we handle this part.
In the end, we can say that there are more or less complex methods to accomplish this, which are selected based on the type of part, its size, the required productivity, and a bunch of other factors that would be pointless to list here.
