Abstract We describe the procedure to obtain composites made of a nickeliron alloy and magnetite. A KOH concentration of 14 mol/liter is required. Metal diffraction lines are broad, due to heterogeneous composition and bad crystallization. Balls of metal μm wide stuck to magnetite octahedra are easily observed by SEM and TEM.
This work concerns the effect of final heat treatment on the structure and magnetic properties of tapes,, and mm thick of softmagnetic alloys 79NM, 50N, and 50NP in constant and alternating fields with a frequency of 509600 Hz. The chemical composition of the alloys is given in Table 1.
iron, cobalt, nickel, and others. Not only metals are magnetic. Any element with unpaired electrons will be paramagnetic to some degree. At room temperature however, the only three metals that are ...
About Iron Nickel Cobalt Alloy. Iron Nickel Cobalt is one of numerous metal alloys sold by American Elements under the trade name AE Alloys™. Generally immediately available in most volumes, AE Alloys™ are available as bar, ingot, ribbon, wire, shot, sheet, and foil. Ultra high purity and high purity forms also include metal powder,...
a type of rock that is commonly found with gold and has a magnetic charge, thus it is called magnetite. Also, it contain iron ore, or iron oxide (Fe2 O3) so the color is usually reddish brown. the ...

Oct 27, 2015· Permanent magnets. The most common metals used for permanent magnets are iron, nickel, cobalt and some alloys of rare earth metals. There are two types of permanent magnets: those from "hard" magnetic materials and those from "soft" magnetic materials. "Hard" magnetic metals tend to stay magnetized over a long period.
Iron, the most ubiquitous of the transition metals and the fourth most plentiful element in the Earth's crust, is the structural backbone of our modern infrastructure. It is therefore ironic that as a nanoparticle, iron has been somewhat neglected in favor of its own oxides, as well as other metals such as cobalt, nickel, gold, and platinum.
The nickeliron alloys possess the highest permeability by far of all the soft magnetic alloys. They generally have been used in the most discerning, often scientific applications where parts are intricately involved and frequently where low weight, limited space and/or miniaturization are important factors.
Oct 29, 2003· Stainless steels. The most common stainless steel is the 304 grade with 8% nickel and 18% chromium and the balance iron. This is used for such common items as spoons and forks, saucepans and kitchen sinks. Where extra corrosion resistance is required, such as for roofing in marine applications, type 316 is used.
