Nano-Cobalt

Technical Parameters

Note: according to user requirements of nano particle can provide different size products.

Application direction

        1 High-density magnetic recording materials: using nanometer cobalt powder record high density and high coercive force (up to 119.4 KA/m), signal-to-noise ratio and oxidation resistance as well as good, can significantly improve tapes and large capacity hard disk performance;

        2 Magnetic iron, cobalt, nickel alloy powder production of magnetic and outstanding performance, can be widely applied in medical apparatus and instruments, sealing damping, sound, light show;

        3 Absorbing materials of nano metallic electromagnetic wave absorb have special effect. Iron, cobalt, zinc oxide powder and carbon bag as military use metallic powder materials, high-performance millimeter-wave invisible infrared stealth materials and visible - stealth materials, and structured mobile phone radiation shielding materials.

Storage conditions

        This product should be stored in dry, cool and sealing of the environment, can not be exposure to air, in addition should avoid the heavy pressure, according to ordinary goods transportation.

Sub-micron Cobalt
