China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Bar magnets are a common type of magnet, also known as rectangular magnets or block magnets. They are widely used in various fields such as educational tools, door magnets, sensors, toys, motors, and packaging. Their cost is influenced by multiple factors, as detailed below.
The main factors affecting the cost of bar magnets include material, size and volume, grade, tolerance, coating (surface treatment), special processing, and minimum order quantity.

To reduce the cost of bar magnets, ferrite is the preferred material (ferrite bar block magnets). Ferrite is much less expensive and is suitable for applications that do not require high magnetic strength.
In terms of bar magnet dimensions, the more material used, the higher the cost. To reduce costs, you can choose smaller, thinner bar magnets.
In addition to size, tolerances also affect unit prices. If tolerances are strict (e.g., only positive or negative tolerances are allowed), unit prices will be slightly higher.
Let's talk about coatings. Not only neodymium magnets can be electroplated, but ferrites can too. Of course, neodymium magnets are usually electroplated. In terms of coating types, zinc is cheaper than nickel, and nickel is cheaper than epoxy.
In terms of processing difficulty, ordinary straight bars are inexpensive to produce, but if special processing such as drilling holes, chamfering, or slotting is required, the processing cost will be higher.
There is another issue that many people tend to overlook, which is the grade. Whether it is neodymium, ferrite, or samarium cobalt, there are many performance grades, and the higher the grade, the higher the price.
