Usages metallic nano iron powder Fe,Cu,Ni,Zn,Ag,Sn,Bi,Co
Appearance: Iron nanoparticles are black, no other color mixed, ball shape, no obvious agglomerate.
High-performance magnetic recording materials: With its advantages including high coercivity, high saturation magnetization intensity (up to 1477km2/kg), signal-to-noise ratio and good oxidation resistance, it remarkably improves the performance of tape, large-capacity hard disk and soft disk.
Magnetic fluid: The magnetic fluid made of iron, cobalt, nickel and its alloy particles provide excellent properties, they are widely used in seal shock absorption, medical equipment, acoustic adjustment, optical display, etc.
Microwave-absorption materials: Metal nanoparticles has special absorbing ability to electromagnetic wave. Iron, cobalt. Zinc oxide particles and its carbon package particles can be used as military high-performance millimeter wave invisible materials, visible light-infrared invisible materials and structural type invisible, and mobile radiation shielding materials.
Magnetic-conductive paste: With the advantages of high saturation magnetization and high magnetic inductivity of iron nanoparticle, magnetic conductive size can be made, it is used for the binding structure of fine magnetic head.
Agent-driven Nano: Some with magnetic nanoparticles, as the carrier made its agent-oriented, will enable the drug under the outer magnetic field gathered at a local body so as to the location of the pathology of the high concentration of drug treatment, particularly for cancer, tuberculosis, and so on.
