Nickel has excellent mechanical, physical andchemical properties, to add a suitable element can improve its oxidationresistance, corrosion resistance, high temperature dth drill bits strength and improve certainphysical properties. Nickel alloys as electron tubes, precision alloy (magneticalloy, precision resistance alloys, electric alloys, etc.), nickel-basedsuperalloy, nickel-based corrosion resistant alloys and shape memory alloy.Energy development, chemicals, electronics, marine, aviation and aerospacesectors, nickel alloy has a wide range of uses.

As the surveys by metal powder supplier, nickel cancompose of a variety of alloys like copper, iron, manganese, chromium, silicon,magnesium. The nickel-copper alloy is famous monel, its high strength, goodplasticity, in the atmosphere below 750 degrees the chemical stability is good,and widely used in the electrical industry, vacuum tubes, chemical industry,medical equipment and sailing ship industrial.

The nickel base superalloys: the eccentric drill bits mainalloying elements are chromium, tungsten, molybdenum, cobalt, aluminum,titanium, boron, zirconium, etc.. Which chromium has the effect of antioxidantand anti-corrosive, the other elements have strengthening effect. Under a hightemperature of 650 to 1000 ¡ã C has a high strength and anti-oxidation, anti-gascorrosion resistance is the most widely applied in the high-temperature alloys,high temperature and the highest intensity of a class of alloys. Used in themanufacture of aircraft engine blades and rocket engines, temperatures on partsof the nuclear reactor, energy conversion devices.

Nickel-based corrosion resistant alloys:the major alloying elements are copper, chromium, and molybdenum. Has a goodoverall performance, resistance to acid corrosion and stress corrosion. Thefirst application is the nickel-copper alloy, also known as monel; in additionto there are also have the nickel-chromium alloy, nickel-molybdenum alloys,nickel-chromium-molybdenum alloy, etc. Used in the manufacture of a variety ofcorrosion-resistant parts.

A nickel-base wear-resistant alloy: themain alloy elements are chromium, molybdenum, tungsten, also contains a smallamount of niobium, tantalum, and indium. Except for the wear resistance performance,it also with good anti-oxidation, corrosion, welding performance. Can bemanufactured wear parts, can also be used as the coating material to be coatedon the surface of the other base material through the surfacing and sprayingprocess.

The nickel-base the precision alloy:nickel-based soft magnetic alloys, nickel-based precision resistance alloys andnickel-based alloys for electrical heating. The most commonly used softmagnetic alloy containing about 80% nickel, permalloy, its maximum permeabilityand the starting high permeability, low coercive force, is the core material whichimportant to the electronics industry. The main alloy element is chromium,aluminum, copper nickel base precision resistor alloy, this alloy has a highresistivity and low temperature coefficient of resistivity and good corrosionresistance, for the production of resistors. Nickel base electrothermal alloy isnickel alloy containing 20% chromium, has a good oxidation resistance,corrosion resistance, long-term use at a temperature of 1000 ~ 1100 %3.

Nickel-based shape memory alloys: a nickelalloy containing 50% titanium. Its response temperature is 70 ¡ã C, the shapememory effect is good. The small changes in the ratio of nickel-titaniumcomposition, the recovery temperature can be varied within the range of 30 ~ 100 %3.And more used in the manufacture of the spacecraft automatically openstructural parts, the self-excitation fasteners aerospace industry, bio-medicaluse of the artificial heart motor.
