① Nickel base Superalloy. The main alloy elements are chromium, tungsten, molybdenum, cobalt, aluminum, titanium, boron, zirconium and so on. Chromium oxidation and corrosion resistance, other elements to strengthen the role. At 650~1000℃ high temperature, it has high strength, anti-oxidation and corrosion resistance, which is the most widely used and high temperature alloy in high-temperature alloys. More scarce talent in this area is mainly concentrated in the steel Network of excellence. For the manufacture of aero-engine blades and rocket engines, nuclear reactors, energy conversion equipment, high temperature components.
② nickel base corrosion resistant alloy. The main alloying elements are copper, chromium and molybdenum. With good comprehensive performance, can withstand all kinds of acid corrosion and stress corrosion. The first application is nickel-copper alloy, also known as Monel alloy, in addition to nickel-chromium alloy, nickel-molybdenum alloy, nickel-chromium-molybdenum alloy. For the manufacture of various corrosion-resistant parts.
③ nickel base wear-resistant alloy. The main alloying elements are chromium, molybdenum and tungsten, and also contain a small amount of niobium, tantalum and Indium. In addition to wear resistance, its antioxidant, corrosion resistance, welding properties. It can make wear-resistant parts, also can be used as cladding material, and is covered by surfacing and spraying process on other substrate material surface.
④ nickel base Precision alloy. Including nickel based soft magnetic alloy, nickel-based precision resistance alloy and nickel-based electric alloy. The most commonly used soft magnetic alloy is nickel containing about 80% of the vitrified, its maximum permeability and initial permeability high, low coercivity, is an important iron core materials in the electronics industry. The main alloying elements of nickel-based precision resistance alloys are chromium, aluminum and copper, which have high resistivity, low resistivity temperature coefficient and good corrosion resistance, and are used for making resistors. Ni-based electrothermal alloy is chromium 20% nickel alloy, with good anti-oxidation, corrosion resistance, can be used in 1000~1100℃ temperature for a long time.
