Jun 05, 2017

Shan nickel-base Superalloy. The main alloying elements are chromium, tungsten, molybdenum, cobalt, aluminum, titanium, boron, zirconium and so on. Among them, chromium plays an important role in antioxidation and corrosion resistance and other elements. It has high strength, anti-oxidation and gas corrosion resistance at high temperature, and is the most widely used alloy in high-temperature alloy with the highest 650. The shortage of talent in this area is mainly concentrated in the steel Network of excellence. It is used for the manufacture of high temperature components on aero-engine blades and rocket engines, nuclear reactors and energy conversion equipment.

Shan nickel based corrosion resistant alloy. The main alloying elements are copper, chromium and molybdenum. Has good comprehensive performance, can withstand all kinds of acid corrosion and stress corrosion. Nickel-copper alloys, also known as Monel alloys, are the first to be used, as are nickel-chromium alloys, nickel-molybdenum alloys, and nickel-chromium-molybdenum alloys. Used for manufacturing various corrosion resistant parts.

Shan Nickel base wear-resisting alloy. The main alloying elements are chromium, molybdenum and tungsten, and contain a small amount of niobium, tantalum and Indium. In addition to wear-resistant properties, its antioxidant, corrosion resistance, welding performance is good. Can be manufactured wear-resistant parts, can also be used as a coating material, through the surfacing and spraying process to cover the surface of other substrates material.

Shan nickel base Precision alloy. Including nickel-based soft magnetic alloy, nickel-based precision resistance alloy and nickel-based electrothermal alloy. The most commonly used soft magnetic alloy is about 80% of the ni-mo alloys, its maximum permeability and initial permeability is high, the coercivity is low, is an important iron core material in the electronic industry. The main alloying elements of Ni-based precision resistance alloy are chromium, aluminum and copper, which has high resistivity, low resistivity temperature coefficient and good corrosion resistance, and is used for making resistors. Ni-based electrothermal alloy is a nickel alloy containing chromium 20%, has a good antioxidant, corrosion resistance, can be used in the 1000 1100 temperature for a long time.

Shan nickel-based shape memory alloy. Nickel alloy containing titanium (at)%. Its response temperature is 70 Shan, shape memory effect is good. A small change in the proportion of Ni-ti composition can change the response temperature within the 30 range. Used in the manufacture of spacecraft on the use of automatic open structural parts, aerospace industry, the use of self-excitation fasteners, biomedical applications of artificial heart motor.
