Overview of Nickel Resources

Nickel is a ferromagnetic metal element with excellent properties such as corrosion resistance, high temperature resistance, oxidation resistance, and good ductility. It is widely used in metallurgy, chemical industry, aerospace and other fields, and is an important raw material for the preparation of stainless steel, high-temperature alloys, power batteries and other materials. It is a key strategic metal resource. The world's nickel resources are mainly distributed in Indonesia, Australia, Brazil, and Russia, while the proportion of nickel reserves in China is insufficient3%It belongs to a typical "low nickel" country.

Definition of nickel based alloys

generallyNiContent exceeds30wt%The alloy is called nickel based alloy, which is a common productNiThe content exceeds50wt%Due to its superior high-temperature mechanical strength and corrosion resistance, it is collectively referred to as a superalloys with iron-based and cobalt based alloys(Superalloy)Usually applied in540High temperature environments above ℃, with different alloy designs selected according to their usage scenarios, are often used for special corrosion-resistant environments, high-temperature corrosive environments, and equipment that requires high-temperature mechanical strength.

Application of nickel and nickel alloys

Nickel and nickel alloys are an important strategic material with excellent properties, such as extremely good corrosion resistance, thermal strength, excellent processability, as well as special functional properties such as electromagnetics and memory. Their processed materials are high value-added products and are one of the hot metals in research at home and abroad.

Nickel alloys can be divided into high-temperature alloys, corrosion-resistant alloys, memory alloys, wear-resistant alloys, and precision alloys according to their intended use. Nickel alloys have excellent corrosion resistance, high temperature strength, oxidation resistance, and some special alloys also have special functions such as memory and excellent electromagnetics. Therefore, they are widely used in industrial fields such as military aerospace, aerospace, electrical and electronic engineering, petrochemicals, and new energy.

Characteristics of nickel based alloys

Nickel based alloys are the most widely used and high-strength materials in superalloys. The name superalloys comes from the characteristics of the material.

including:

Superb performance

High strength can be maintained at high temperatures, and it has excellent mechanical properties such as resistance to creep and fatigue, as well as oxidation and corrosion resistance, and good plasticity and weldability.

Alloy addition is extremely complicated

Nickel based alloys often add more than ten alloying elements to enhance their corrosion resistance in different environments; And it also has the effects of solid solution strengthening or precipitation strengthening.

The working environment is extremely harsh

Nickel based alloys are widely used in various harsh operating conditions, such as high-temperature and high-pressure parts of aerospace engine gas chambers, structural components in nuclear, petroleum, and marine industries, corrosion-resistant pipelines, etc.
