Neodymium Ball Magnets 12.7mm

12.7mm is an intermediate dimension for spherical rare earth neodymium magnets, it is also a popular size in the USA market. The pulling strength of N42 neodymium ball magnets of 12.7mm is about 2.7kg. Higher grades can be customized for greater force. Most 12.7mm neodymium sphere magnets bulk are plated with nickel or chromium, other plating (like as Au and Ag) can be customized. If two strong magnetic balls collide, the coating at the contact point will fall off due to the strong impact force. Do not let children play with the magnetic ball alone including neodymium magnetic balls 10mm and 5mm magnetic balls wholesale.
