Product information:
1) Our hollow conductors are made from high-conductivity,oxygen-free copper,which is a high puritycopper with an electrical conductivity of at least 100%IACS,material alloy number in C10100,C10200 and C11000.Our products have high electrical and thermal conductivity and braze-ability and weld-ability.And also in highly precisionof diameter tolerance.
2) Copper hollow conductors re most commonly used in the industry of magnet,electric motors and generators.And it applied for following products:
1 Coils for induction furnaces
2 Coils for induction heaters
3 Magnet coils for proton synchrotrons
4 Coils for welding machines
5 Field coils for generators
6 Stator coils for generators
7 Conductors for rectifiers
8 Magnet coils for plasma research equipments
9 Ahielded pipe for vacuum electeic equipmrnt
