① Nickel base superalloy. The main alloying elements are chromium, tungsten, molybdenum, cobalt, aluminum, titanium, boron, zirconium and so on. Among them, chromium plays an anti-oxidation and anti-corrosion role, and other elements play a strengthening role. It has high strength, oxidation resistance and gas corrosion resistance at 850 ~ 1300℃. It is the most widely used alloy with the highest high temperature strength. Used in the manufacture of aero-engine blades and high-temperature components for rocket engines, nuclear reactors and energy conversion equipment.
② Nickel base corrosion resistant alloy. The main alloying elements are copper, chromium and molybdenum. It has good comprehensive properties and can resist various acid corrosion and stress corrosion. The earliest application is nickel-copper alloy, also known as Monel alloy; In addition, there are nickel-chromium alloy, nickel-molybdenum alloy, nickel-chromium molybdenum alloy and so on. Used for manufacturing various corrosion resistant parts.
③ Nickel base wear resistant alloy. The main alloying elements are chromium, molybdenum and tungsten, with small amounts of niobium, tantalum and indium. In addition to wear resistance, its oxidation resistance, corrosion resistance, welding performance is good. It can be used to manufacture wear-resistant parts, or as coating material, which can be coated on the surface of other matrix materials by surfacing and spraying process.
④ Nickel base precision alloy. Including nickel base soft magnetic alloy, nickel base precision resistance alloy and nickel base electric heating alloy. The most commonly used soft magnetic alloy is the bose alloy containing about 80% nickel, which has high maximum permeability and initial permeability, low coercivity, and is an important iron core material in the electronics industry. The main alloying elements of nickel-based precision resistance alloy are chromium, aluminum and copper. This alloy has high resistivity, low resistivity temperature coefficient and good corrosion resistance, and is used for making resistors. Nickel-based electric heating alloy is a nickel alloy containing 20% chromium, has good oxidation resistance, corrosion resistance, can be used in 1000 ~ 1100℃ temperature for a long time.
Nickel base shape memory alloy. Nickel alloys containing 50 (at)% titanium. Its recovery temperature is 70℃, shape memory effect is good. The recovery temperature can be changed from 30 ℃ to 70 ℃ by changing the composition ratio of ni to Ti. It is mainly used in the manufacture of automatic opening structures used in spacecraft, self-excitation fasteners used in aerospace industry, artificial heart motors used in biomedicine and so on.
