FAQ
Q1. Do you have any MOQ limit for neodymium magnet order?
A1. Low MOQ, 1pc for sample checking is available
Q2. How do you ship the goods and how long does it take to arrive?
A2. We usually ship by DHL or FedEx. It usually takes 3-5 days to arrive. Airline and sea shipping also optional.
Q3. Why are neodymium magnets coated?
A3. Neodymium magnets coatings are used to protect the neodymium magnets. Neodymium is easy to react to oxygen and oxidizes quickly if untreated. That's why all neodymium magnets are covered with a protective coating, which is so thin that it doesn't have any impact on the adhesive force of the magnet.
Q4. What is the coating on neodymium magnets?
A4. The typical coating for a neodymium magnet is a layer of nickel followed by a layer of copper and then nickel again. However there are many different coatings used with neodymium magnets including gold, rubber and Polytetrafluoroethylene (PTFE).
Q5. What is the difference between nickel plated and zinc plated?
A5. The key difference between zinc and nickel plating is that zinc plating involves applying a thin coating of zinc on a conductive substance whereas nickel plating involves the application of a thin layer of nickel on a metal surface.
