Nickel is a silvery-white metal with excellent mechanical strength and ductility. It is insoluble in water, has strong resistance to acids and alkalis, but is readily soluble in dilute nitric acid and aqua regia. High-temperature resistant, melting point 1455 °C, boiling point 2730 °C. The density is 8.902g/cm³. It can be used to make currency and so on. When plated on other metals, it can prevent rusting.
Nickel has excellent plasticity, corrosion resistance and magnetic properties, and is therefore mainly used in fields such as steel, nickel-based alloys, electroplating and batteries. It is widely applied in various military manufacturing industries such as aircraft and radar, civil machinery manufacturing and electroplating industries. Nickel composite materials can be used as catalysts in hydrogenation and methane synthesis in petrochemicals. Their advantage is that they are not easily poisoned by H2S and SO2.

Nickel, with an atomic number of 28 and an atomic weight of 58.6934, is located in Group VIII of the fourth period. It is a hard, malleable, ferromagnetic transition metal with a silvery-white luster. Nickel has excellent thermal and electrical conductivity, and possesses outstanding properties such as strong plasticity, high-temperature resistance, corrosion resistance, stable chemical properties, and strong oxidation resistance.

Nickel-iron alloy particles are an alloy material composed of nickel and iron, with the nickel content generally ranging from 20% to 60%. Nickel-iron alloy materials have a relatively high density (8.1 to 8.4 g/cm³), a melting point ranging from 1430 to 1480 degrees, and possess excellent heat resistance and corrosion resistance. It is widely used in magnetic materials, the electronics industry, powder metallurgy, motors and generators, etc.

High-purity nickel particles are silver-white metal in appearance, with a density of 8.902g/cm ³, a melting point of 1453 ° C, and a boiling point of 2732 ° C. They possess magnetic properties and good plasticity. It is a metallic element with good corrosion resistance, being hard, malleable and ferromagnetic. It can be highly polished and resistant to corrosion. It turns green after dissolving in nitric acid. It is mainly used in alloys (such as nickel-steel and nickel-silver) and as a catalyst (such as Raney nickel, especially as a catalyst for hydrogenation).

Nickel alloy is a metal in which a certain proportion of nickel is contained in its elemental composition. Nickel mainly forms alloys with chromium, copper, iron, titanium and molybdenum. Each of these alloy combinations has specific properties that make it suitable for a specific range of applications. For instance, chromium-nickel-iron alloy possesses excellent corrosion resistance, oxidation resistance and high-temperature resistance. Most nickel alloys exhibit good corrosion resistance, oxidation resistance and high-temperature strength properties, but there are some exceptions. Nickel-iron alloys do not have the same level of corrosion resistance and oxidation resistance. Nickel alloys are typically used in extreme working environments, such as those encountered in aerospace, chemical processing and the petroleum industry, but they can also be used in electrical and electronic applications.

Nickel-chromium alloy particles are silver-gray metal particles. They come in various sizes and can be used as evaporation source materials. This alloy has excellent resistance to high-temperature oxidation and corrosion, as well as good wear resistance. Density: 8.65 Mg/m ³, melting point: 937℃, hardness: 6000 MPa.
