More Nickel Suppliers

Nickel is utilized across various applications, including product coating, electroless nickel plating, metal alloy creation, and fabrication. It also plays a role in ensuring clean drinking water, and supporting power, heating, and lighting systems.

Nickel is supplied to diverse industries such as military and defense, electronics, coinage, food and beverage, aerospace, marine, architecture, chemistry, and industrial manufacturing. Additionally, while some jewelers incorporate nickel into their designs, they typically reserve it for lower-cost items due to its potential to cause allergic reactions in some individuals.

History of Nickel

Isolated and identified as a chemical element in 1751, nickel, a silvery-white metal, has been found in tools dating back to 3500 BC. Archaeologists discovered these ancient tools, containing at least 2% nickel, in ruins in present-day Syria. Chinese manuscripts indicate the use of cupronickel (an alloy of copper and nickel) between 1700 BC and 1400 BC, referred to as “white copper” or baitung. By around 1095 AD, the scholar Ho Wei documented the cupronickel production process. The Hellenistic society also utilized nickel; between 180 BC and 170 BC, Greco-Bactrian kings, such as Agathocles, Pantaleon, and Euthydemus II, minted coins with about 20% nickel. It is speculated that these kings may have imported nickel from China, though this remains unconfirmed.

Nickel, named after a mischievous sprite from German mythology, was first identified by Swedish chemist Axel Cronstedt in 1751. He derived the name from the ore now known as nickeline or niccolite, which medieval miners in the Ore Mountains had named kupfernickel. “Kupfer” means copper, and “nickel” referred to the sprite, reflecting the miners’ disdain for the ore that hindered copper extraction and caused illness due to its arsenic content. Cronstedt dropped the “kupfer” from the name when he isolated nickel.

In the 1800s, nickel became widely used in plating and coin production. The creation of nickel silver, an alloy of nickel, zinc, and copper (despite its name, it contains no actual silver), marked a significant development. In 1866, the American government began minting nickel-based coins (75% copper, 25% nickel) to economize following the Civil War. Previously, coins like half dimes were made from more expensive silver. By 1881, Switzerland introduced its first pure nickel coins. Nickel’s role expanded in the 20th century with its inclusion in stainless steel, enhancing its corrosion and temperature resistance. Today, nickel is integral to various industries, from chemical plants to everyday kitchen items, and is used in the coinage of many countries, including the United States and the European Union.

Nickel Production Process

The process of converting nickel ore into usable products begins with its extraction from the earth. Nickel ore is found in two primary forms: laterites and magmatic sulfide deposits. Laterites, which are encountered in tropical weathered soils, are predominantly composed of minerals such as garnierite and nickeliferous limonite. In contrast, magmatic sulfide deposits, formed from cooling magma, are mainly made up of pentlandite, a crucial ore mineral.

Once the nickel ore is extracted, it undergoes extractive metallurgy to refine and purify it. This phase involves techniques such as pyrometallurgical extraction and hydrometallurgy. These methods are essential for transforming the raw ore into a more purified form. During the roasting and reduction stage, traditional techniques yield nickel with a purity level exceeding 75%. For a higher degree of purity, the Mond process is employed, which converts nickel oxides into nearly pure nickel using carbon monoxide, resulting in a compound known as carbonyl nickel.

Nickel Fabrication

After the refining process, nickel is subjected to various fabrication techniques to achieve the desired specifications. Key methods include electroless nickel plating, which applies a nickel layer onto surfaces; cold drawing, where the metal is shaped by pulling it through dies at ambient temperatures; and extrusion, a process that forces the metal through a die to produce specific shapes and profiles. These fabrication methods are vital for producing nickel products that meet a wide range of application requirements.

Electroless nickel plating is a meticulous chemical reduction process that achieves the deposition of nickel onto a surface without reliance on electrical energy. This process begins with immersing the surface into a carefully prepared aqueous solution that contains a chemical reducing agent. As the nickel interacts with the solution, a catalytic reduction reaction occurs. This reaction facilitates the even deposition of nickel ions onto the surface of the product. The outcome is a nickel plating that is remarkably uniform, with consistent thickness, shape, and size across the entire surface, ensuring a high-quality finish.

Cold drawing is a methodical process employed to refine the dimensions of nickel wire or tubes. In this technique, manufacturers pass the nickel material through a series of progressively smaller dies, all while maintaining ambient temperatures. This process, free from heat application, effectively reduces the diameter of the nickel, allowing for precise control over the final dimensions and properties of the material.

Extrusion, though less frequently utilized, is a notable method for shaping nickel. During extrusion, manufacturers either melt the nickel or apply significant force to push it through a die. This process enables the production of various forms such as rods, sheets, bars, and tubing. Although extrusion is not as common as other methods, it remains a valuable technique for creating specific shapes and sizes, catering to specialized requirements in the manufacturing process.

Alloys

Nickel ore suppliers often blend nickel with elements like copper, aluminum, titanium, and chromium to create compounds and alloys suitable for various applications. Common alloys include Nickel 200, stainless steel, Kovar, Invar, Monel, Nichrome, Inconel, and various Hastelloys.

Nickel 200 is a specialized alloy consisting of 99.6% pure nickel, known for its exceptional corrosion resistance and stability. To tailor its properties for specific applications, it is alloyed with a range of elements such as copper, iron, carbon, silicon, sulfur, and magnesium. These additions enhance its mechanical strength and performance, making it suitable for demanding environments where high purity and resistance to oxidation are crucial.

Stainless steel is primarily made of iron, with notable additions of 18% chromium and 8% nickel. This composition endows stainless steel with remarkable durability and resistance to corrosion, making it an indispensable material in countless industries. Its versatility and resilience have established it as the most commonly used nickel alloy, favored for its ability to maintain structural integrity and appearance under harsh conditions.

Kovar is a specialized ferrous nickel alloy primarily composed of nickel and cobalt, with small amounts of copper, manganese, and silicon. This alloy is renowned for its compatibility with the thermal expansion characteristics of borosilicate glass, making it ideal for a wide range of applications. Kovar’s unique properties make it particularly suitable for use as electroplated conductors in critical system components, such as x-ray tubes and vacuum tubes.
