Answer One description: A process used to determine if a head is cracked. The head is magnatized using a powerful electromagnet, then iron filings are sprayed on the head to check for cracks. Patterns in the filings indicate either a cracked or normal head. This process works on cast iron heads but not on aluminum heads.
The answer given above is incorrect. Magnaflux is a product use to check for cracks and other discontinuities, but it has nothing to do with Magnetization. Magnaflux is a (3) part process using (a) Cleaner (b) Penetrant (c) Developer. The answer given above would be for the question, "What is Mag-particle Testing"?

Will magnaflux work on aluminum?
First; will a magnet stick to aluminum? Next, google, "Magnaflux". Thank you.
The magnaflux process can used to detect cracks in?
Cast iron heads.
How do I detect cylinder block cracks?
You can "Magnaflux" the block assuming the block is cast iron or steel and the block is stripped down and cleaned for rebuilding.
How do you recondition crankshaft?
You get it out, clean it, check that it's straight, magnaflux it for cracks, clear out the oil channels. If needed, grind down the bearing surfaces to the next standard dimension.
How do you tell if you have a cracked block Chevy 350?
A physical inspection can often reveal obvious cracks on the sides. Also, you can get a magnaflux inspection which uses iron powder and an electromagnet to identify cracks. Short of that, check for leaks.
What is the advantages of the magnetic strip?
Motors and generators are useful devices that use the magnetic effect in a positive way. Several manufacturing processes also use the effect for separating out ferrous metals and detecting flaws in metals. Magnaflux is one example.
Piston's seized in block?
Disassemble it as far as you can then take it to an automotive machine shop. They'll need to magnaflux and bore the engine and head(s) before you can trust it. They'll get the piston out and if the block isn't damaged beyond repair they can help get your engine back into shape.
Determining a head gasket problem 1988 ford ranger?
== == I used to stick the "sniffer" of a smog machine into the radiator (after draining out some coolant) while in the manual gas reading mode. any HC's and you know you got a problem. Only way to tell if it's a cracked head or just a gasket is to pull it and magnaflux/dye test the head
What do all the barrel markings on a Remington model 721 30.06 mean?
Markings typically include model, The Remington trademark, date of manufacture, test marks, inspectors, and proof mark. In some cases it may be a factory repair mark, or indication of Magnaflux testing. See the link below for an illustration of barrel code markings. Note these are for REMINGTON only.
How do you fix a cracked head in the engine?
Depends where it's cracked. This was a common problem with the 6.2 Detroit Diesels that GM used from 1984 - 1993. You'd have to magnaflux the head, find the cracks, drill a hole and tap it, fill it with a bolt, cut off the remainder of the bolt, then smooth it all down. Not someone you really want to "learn as you go" on your own vehicle.
Which weld test method would be most useful in detecting internal defects?
X - Ray It would depend on the thickness of material. Xray is best of course but very expensive to have done. Magnaflux is probably the most popular and fairly inexpensive. It can detect defects up to approx 1/4" deep. On weld joints thicker than that every 1/4" layer can be done. Surface defects can be detected by Dye penetrant test. Very useful for fine cracks and porosity.
How do you tell if your engine is cracked form a blown headgasket?
Generally, if the headgasket is blown the rest of the engine is probably ok. The only way to determineif the block and/or head is cracked is to pull the head and have the machine shop "magnaflux" the head and/or block. Most often you can get by just machining the head (to make it flat again) then put it all back together. While it's apart it's common AND RECOMMENDED that you have the valves and guides reconditioned. It's relatively cheap while the head is off and can save problems later.
