Strong Suction Permanent Rare Earth Neodymium Magnetic Welding Tool Welding Magent Holder
The magnetic frame is made of strong metal that won't melt while welding and is solidly riveted together. These welding magnets are durable, long lasting, and resistant to rust and corrosion.
While you're welding you'll want to make sure that your work doesn't move around. Holds up high magnetic pull strength for sturdiness needed for welding, soldering.
Strong welding magnets stick solidly to any ferrous metal object. Keep your hands free and enable you to focus on achieving precise welding and making excellent works.

Frequently Asked Questions
Q: What are neodymium magnets? Are they the same as "rare earth"?
A: Neodymium magnets are a member of the rare earth magnet family. They are called "rare earth" because neodymium is a member of the "rare earth" elements on the
periodic table. Neodymium magnets are the strongest of the rare earth magnets and are the strongest permanent magnets in the world.
Q: What does the "N rating", or grade, of the neodymium magnets mean?
A: The grade, or "N rating" of the magnet refers to the Maximum Energy Product of the material that the magnet is made from. It refers to the maximum strength that the
material can be magnetized to. The grade of neodymium magnets is generally measured in units millions of Gauss Oersted (MGOe). A magnet of grade N42 has a Maximum Energy Product of 42 MGOe. Generally speaking, the higher the grade, the stronger the magnet.
Q: What is the difference between the different platings and coatings?
A: Choosing different coatings does not affect the magnetic strength or performance of the magnet, except for our Plastic and Rubber Coated Magnets. The preferred coating is dictated by preference or intended application. More detailed specifications can be found on our Specs page.
Nickel is the most common choice for plating neodymium magnets. It is actually a triple plating of nickel-coppernickel. It has a shiny silver finish and has good resistance
to corrosion in many applications. It is not waterproof.
Black nickel has a shiny appearance in a charcoal or gunmetal color. A black dye is added to the final nickel plating process of the triple plating of nickelcopperblack nickel.
NOTE: It does not appear completely black like epoxy coatings. It is also still shiny, much like plain nickel plated magnets.
Zinc has a dull gray/bluish finish, that is more susceptible to corrosion than nickel. Zinc can leave a black residue on hands and other items.
Epoxy is basically a plastic coating that is more corrosion resistant as long as the coating is intact. It is easily scratched. From our experience, it is the least durable of
the available coatings.
Gold plating is applied over the top of standard nickel plating. Gold plated magnets have the same characteristics as nickel plated ones, but with a gold finish.
