An alloy made of nickel and other elements is called nickel alloy. Nickel has good mechanical, physical and chemical properties. Adding appropriate elements can improve its oxidation resistance, corrosion resistance, high temperature strength and some physical properties. Nickel alloys can be used as materials for electronic tubes, precision alloys (magnetic alloys, precision resistance alloys, electrothermal alloys, etc.), nickel base superalloys, nickel base corrosion resistant alloys and shape memory alloys. Nickel alloys are widely used in energy development, chemical industry, electronics, navigation, aviation and aerospace.
Nickel base alloy is a kind of alloy with high strength, oxidation and corrosion resistance at 650 ~ 1000 ℃. According to the main properties, it is subdivided into nickel base heat resistant alloy, nickel base alloy, nickel base alloy, nickel base precision alloy and nickel base shape memory alloy. According to the different matrix, superalloys are divided into iron-based superalloys, nickel based superalloys and cobalt based superalloys. Nickel base superalloy is called nickel base alloy for short.
Nickel alloy is widely used in desulfurization industry. The main reason is that it has strong acid resistance and strong corrosion resistance to halogen ions. The corrosion resistance of various nickel alloy materials varies with the content of alloy elements.
Since World War II, "superalloy" has been used to describe a group of alloys developed in turbochargers and aircraft turbine engines, which need performance at high temperatures. The application of superalloys has been extended to many other fields, including aircraft and land-based gas turbines, rocket engines, chemical and petroleum plants. They are suitable for these demanding applications. Alloys are based on VIIIB group elements and are usually composed of various combinations of Fe, Ni, CO and Cr and small amounts of W, Mo, Ta, Ti and al. The three main alloys are nickel, iron and cobalt based alloys. Next, xincoral Xiaobian will share with you the development of nickel base alloy.

Nickel can form a variety of alloys with copper, iron, manganese, chromium, silicon and magnesium. Nickel copper alloy is a famous Monel alloy with high strength and good plasticity. It has stable chemical properties in the atmosphere below 750 degrees. It is widely used in electrical industry, vacuum tube, chemical industry, medical equipment and marine industry.

Definition of nickel base alloy

Nickel base alloys are generally called alloys with Ni content of more than 30wt%, and common products have Ni content of more than 50wt%. Due to their high-temperature mechanical strength and corrosion resistance, they are called superalloys together with iron-based and cobalt based alloys. They are generally used in high-temperature environments above 540 ℃, and different alloy designs are selected according to their application occasions. They are mostly used in corrosion-resistant environments, high-temperature corrosion environments Equipment with high temperature mechanical strength is required. It is often used in aerospace, energy, petrochemical industry or electronic / photoelectric fields.
