Complete knowledge of nickel base alloys you don't know
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.

What are the classification and characteristics of nickel base corrosion resistant alloys?
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.
Performance comparison between pure nickel and copper nickel alloy
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.
History of nickel base alloys
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.
Cost performance of imported electric heating wire and domestic alloy wire
As we all know, the most important thing to buy a thing is its cost performance. The cheaper it is, the better it is, and the more expensive it is, the more suitable it is. When selecting a product, we should analyze its cost performance. The price is appropriate and the quality is excellent.
