This is a kind of high strength Ndfeb square magnet, the length and width of 20mm, thickness is relatively thick, 7mm, thickness direction magnetization, can be used in the environment less than 80℃, if you need to change the high temperature in the environment temperature, such as M, SH grade, mainly used in machinery, industry, if you think the thickness is thick, Can also be processed into 1-3mm thick, so the cost will be lower.

Safety: The magnet is not a toy. Please place it out of the reach of children and ensure that children do not play with the magnet to avoid injury.
Thinner and smaller sizes are recommended;
