Nickel powder mainly used in chemical catalyst, flux cored wire, magnetic materials, diamond tools. Based on nickel adding other elements called nickel alloy composition of the alloy.
Nickel has excellent mechanical, physical and chemical properties, to add a suitable element can improve its oxidation resistance, corrosion resistance, high temperature strength and improve certain physical properties. Nickel alloys as electron tubes, precision alloy (magnetic alloy, precision resistance alloys, electric alloys, etc.), nickel-based superalloy, nickel-based corrosion resistant alloys and shape memory alloy. Energy development, chemicals, electronics, marine, aviation and aerospace sectors, nickel alloy has a wide range of uses.
As the surveys by metal powder supplier, nickel can compose of a variety of alloys like copper, iron, manganese, chromium, silicon, magnesium. The nickel-copper alloy is famous monel, its high strength, good plasticity, 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 main alloying elements are chromium, tungsten, molybdenum, cobalt, aluminum, titanium, boron, zirconium, etc.. Which chromium has the effect of antioxidant and anti-corrosive, the other elements have strengthening effect. Under a high temperature of 650 to 1000 ° C has a high strength and anti-oxidation, anti-gas corrosion resistance is the most widely applied in the high-temperature alloys, high temperature and the highest intensity of a class of alloys. Used in the manufacture of aircraft engine blades and rocket engines, temperatures on parts of the nuclear reactor, energy conversion devices.
Nickel-based corrosion resistant alloys: the major alloying elements are copper, chromium, and molybdenum. Has a good overall performance, resistance to acid corrosion and stress corrosion. The first application is the nickel-copper alloy, also known as monel; in addition to there are also have the nickel-chromium alloy, nickel-molybdenum alloys, nickel-chromium-molybdenum alloy, etc. Used in the manufacture of a variety of corrosion-resistant parts.
A nickel-base wear-resistant alloy: the main alloy elements are chromium, molybdenum, tungsten, also contains a small amount of niobium, tantalum, and indium. Except for the wear resistance performance, it also with good anti-oxidation, corrosion, welding performance. Can be manufactured wear parts, can also be used as the coating material to be coated on the surface of the other base material through the surfacing and spraying process.
The nickel-base the precision alloy: nickel-based soft magnetic alloys, nickel-based precision resistance alloys and nickel-based alloys for electrical heating. The most commonly used soft magnetic alloy containing about 80% nickel, permalloy, its maximum permeability and the starting high permeability, low coercive force, is the core material which important to the electronics industry. The main alloy element is chromium, aluminum, copper nickel base precision resistor alloy, this alloy has a high resistivity and low temperature coefficient of resistivity and good corrosion resistance, for the production of resistors. Nickel base electrothermal alloy is nickel alloy containing 20% chromium, has a good oxidation resistance, corrosion resistance, long-term use at a temperature of 1000 ~ 1100 .
Nickel-based shape memory alloys: a nickel alloy containing 50% titanium. Its response temperature is 70 ° C, the shape memory effect is good. The small changes in the ratio of nickel-titanium composition, the recovery temperature can be varied within the range of 30 ~ 100 . And more used in the manufacture of the spacecraft automatically open structural parts, the self-excitation fasteners aerospace industry, bio-medical use of the artificial heart motor.

The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
Exploring the Potentials of Nano-Aluminum Powder
Nano-aluminum powder, a material with remarkable properties due to its minuscule particle size, is revolutionizing various industries with its high reactivity and large specific surface area. Unlike its bulk counterpart, nano-aluminum powder begins to oxidize at a lower temperature of 550°C, compared to the 950°C oxidation point of ordinary aluminum. This lower ignition energy and full combustion without apparent cohesion make it a superior choice for applications requiring high energy and efficiency. The unique characteristics of nano-aluminum powder, such as faster burning rates and greater heat release, are largely influenced by its synthesis method, which determines its particle size, surface area, and shape.
