The size of Large Magnets are limited because of the brittleness and magnetized direction.Many products need large magnets to work.
6"x4"x1" large ferrite magnets is regular size for seperators.
We manufacture the magnets for regular customers every month.
It seems 6" is popular size , our company manufacture D6"x1" and D4"x1" large disc magnets for new type tester on 2009. Since 2011 , we have manufactured D6"x1" in batch.
To block large magnets,maximium size for magnetization direction is 60mm and maximium length is 180mm, but the grade can be not high , so the size of large magnets is not free to choose.
To the ring, the mini. wall thickness and height can be 3 -4mm , and the out diameter and inner diameter can be 150-100mm. But when be magnetized, we need fixture tool.
To the arc magnets, we have manufactured length 80mm irregular shape for motors.
Relying on Mature Production Process, we manufacture kinds of large magents for users.
