Nickel and Nickel Alloys Nickel alloyed with other metals has made significant contributions to our present-day society. Nickel has been used in alloys that date back to the dawn of civilization. Chemical analysis of artifacts has shown that weapons, tools, and coins contain nickel in varying amounts. Nickel in elemental form or alloyed with other metals and materials has made significant ...

Nickel Electroplating* - CASF

electrocrystallization process so that mirror-bright, highly-leveled nickel coatings are deposited directly from solution. Prior to the introduction of the "organic" baths, decorative nickel coatings were produced by polishing nickel-plated parts mechanically, a practice that continued from 1870 to about 1945.

Nickel laterite ore is used to produce nickel metal, predominantly to manufacture stainless steel as well as nickel sulfate, a key ingredient in the batteries that drive electric vehicles. Nickel laterite production is on the rise and surpassing conventional sulfide deposits. The efficiency of mining and processing nickel laterites is defined by their mineralogical composition.

How Neodymium Magnets are Made - K&J Magnetics

The basic compound for most Neodymium magnets is Nd 2 Fe 14 B. In practice, the actual chemical reaction used can be more complicated. A commonly used reaction is: 57 Fe + 8 B + 10 Fe 2 O 3 + 7.5 Nd 2 O 3 + 52.5 Ca -> Nd 15 Fe 77 B 8 + 52.5 CaO. Note that the powder formed by this reaction is slightly different than the Nd 2 Fe 14 B ratio.

Commodity Nickel - Everything you need to know about Nickel

Nickel is most commonly used as an alloy with either iron or copper (about 90% of nickel is used in alloys). It is used for its defining characteristics such as: high resistance against corrosion, better strength at high and low temperatures, and a range of special magnetic and electronic properties.

The nickel advantage | Nickel Institute

Increasing the nickel content reduces the effect, so that whilst the effect can be quite pronounced in Type 301, Type 310 remains non-magnetic after extensive cold work. The lack of ferromagnetism in the austenitic grades makes it easy to separate them from other stainless steel grades and from carbon steel when scrap is being sorted for recycling.

What is a Magnet? - Definition & Examples - Video & Lesson ...

A magnet is a material or object that produces a magnetic field that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets.

Properties and applications of electroless nickel

Electroless nickel plating is a process for depositing a nickel alloy from aqueous solutions onto a substrate without the use of electric current. It differs, therefore, from electro-plating which depends on an external source of direct current to reduce nickel ions in the electrolyte to nickel metal on the substrate.

Plating - Wikipedia

Plating is a surface covering in which a metal is deposited on a conductive surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity ...

A New Process for Cobalt Nickel Separation

A New Process for Co-Ni Separation – ALTA 2010 2 ABSTRACT A new process has been developed jointly by CSIRO and CESL, for separating cobalt from nickel in an impure leach solution. The process uses synergistic solvent extraction (SSX) with commercially available reagents, but in a novel and efficient manner using kinetic factors.

Chapter 2 Magnetic Materials and Their Characteristics

High permeability metal alloys are based primarily on the nickel-iron system. Although Hopkinson investigated nickel-iron alloys as early as 1889, it was not until the studies by Elmen, starting in about 1913, on properties in weak magnetic fields and effects of heat-treatments, that the importance of the Ni-Fe alloys was realized.

What is magnetic separation? - ChemistryRack

The magnetic separation is a physical separation technique which is based mixtures or using the magnetic properties of the material, such as its sensitivity to the attraction or repulsion magnets. It is also known as magnetization, because the objects that can be separated by this technique are magnetized by the magnetic field of the magnets.
