CMReasons-For-Choosing-Us

Product Description

A channel magnet consists of neodymium magnets encased within a steel channel, significantly enhancing the protective force of the magnet when in direct contact with an object. This design shields fragile magnets from repeated impacts and damage. The magnet is coated to prevent corrosion.

Key Features:
- *Magnetic Force:* The maximum pulling force ranges from 5 kg to 80 kg.
- *Size:* The length varies from 15 mm to 120 mm.
- *Installation:* Countersunk holes allow for secure attachment using countersunk screws. They can also be easily inserted into grooves.
- *Magnetism:* Neodymium magnets are highly magnetic, with their strongest force exerted in the vertical direction.
- *Placement Surface:* The surface must be clean and flat to ensure optimal magnetic performance. Any irregularities or dirt on the surface can reduce the magnet's effectiveness.

FAQ
Q1: Can I place the magnets nearby cellphone or other electronic products?

A: It is no problem for for the magnet in small size such as D8x1mm. But for bigger one such as D50x30mm, we do not suggest you to place the magnets nearby the cellphone. Please be cautious that keep all magnets far away from pacemaker!


Q2: Do you have finished magnets in stock?

A: There are too many specifications of magnets. Different customers needs different grades, sizes, shapes, magnetization orientation, plating, tolerance. So we often make the quantity as customer ordered. For the long-terms customers who frequently buy the same magnets from us, we may have some in stock. Please contact us if you want to know what we have in stock.


Q3: What is the max. and min. size of magnet you can make?

A: We can make the magnet in size from 1x1x0.5mm to 200x100x60mm in block shape and from D1x1mm to D200x50mm for disc magnets. Our sales guy is ready to provide you size details if you need.


Q4: Could magnets be delivered by air for urgent demand?

A: Magnetic shield is necessary for the magnets to be delivered by air. We will put iron plates inside the carton to shield the magnetic force. So you need to inform us if the magnets are delivered by air.


Q5: Is surface treatment necessary for neodymium magnets?

A: The composition of neodymium magnets is mainly neodymium, Iron and boron. The percentage of iron is up to 60%. So it is easy for neodymium magnets to get rusty. The normal plating of neodymium magnets is Zinc, NiCuNi, Epoxy etc. Zinc plating works in dry and clean condition. NiCuNi and Epoxy could be used in humid or bad working condition.


Q6: How to choose the grade of neodymium magnets?
A: The magnetic properties of neodymium magnets could be reduced in the working temperature that exceeds the magnet could stand. So working temperature is a very important factor to decide the grade of neodymium magnets. For example, if the magnets work in the temperature of 110 degrees, you need to buy neodymium magnets at least in H grade.  If the working temperature of magnet exceeds 200 degrees, SmCo magnets or AlNiCo magnets is the best solution.

Br is another factor you need to take into consideration. Higher Br is necessary if you need very powerful magnet. We are always glad to give you professional suggestions about how to choose the grade of magnets

Application Location

Channel magnets are extremely strong and have a wide range of applications due to their powerful magnetic field. They are commonly used in everyday items and situations, such as:
1. Household and Workshop: Neodymium magnets are often used in garages and workshops to hold tools and fasteners securely. They can be attached to toolboxes, walls, or metal surfaces to keep small metal parts like screws, nuts, and bolts organized and within reach.
2. Gardening: Magnets can be used to pick up stray nails or other metal debris from the garden.
3. Automotive: They are used as magnetic brackets for vehicle license plates, holding banners or signs on vehicles, and securing items inside vehicles.
4. Furniture and Appliances: Magnets can be used on doors, cabinets, shelves, and other furniture to create magnetic closures or to hold items in place.

5. Miscellaneous Applications: They are used in various fixed applications where a strong magnetic field is needed, such as in craft projects, DIY repairs, and more.

Neodymium channel magnets are particularly popular because they maintain their magnetic strength over time and can lift or hold significant weight relative to their size. However, they should be handled with care due to their strength and potential to cause injury if not used properly.
