Ni powder is used in industrial applications worldwide such as rechargeable batteries, manufacturing and powder metallurgy. But there's more to nickel powder, some things you probably haven't heard of until now. Did you know that it is also a type of High temperature alloy powder?
l What are the characteristics of nickel powder?
l What types of nickel powder are there?
l Where can nickel powder be used?
1. Ni powder is further divided into carbonyl nickel powder, which is gray irregular powder and is easily oxidized in humid air. Mainly nickel powder, carbonyl nickel powder is used in coatings and plastics as conductive pigments to shield electromagnetic interference and radio frequency interference, used in various high-gloss decorative paints and plastics, and replace aluminum powder as anti-corrosion paint in water systems. Fine spherical nickel powder can be used in conductive inks.
2. Metal pigments with nickel as the main component, including nickel powder and flake nickel powder, are obtained by steam decomposition of purified nickel carbonyl [Ni(CO)4] by distillation. Nickel particles of suitable shape are formed by controlling the temperature, diluting with carbon monoxide and in the presence of gaseous additives (oxygen and nitrogen). Carbon monoxide was washed off with carbon dioxide gas, and the oxygen content on the particle surface was controlled to 0.065%. The latter is high-purity nickel carbonyl powder that is ground in a ball mill with steel balls in the presence of a suitable lubricant and liquid medium to form sheets of suitable thickness.
Ni powder is used in the preparation of non-ferrous alloys, high temperature and oxidation resistant materials, magnetic materials, chemical reaction hydrogenation catalysts, etc. The packaging is made of plastic bags, cloth bags and iron drums lined with protective gas. nickel powder can be divided into electrolytic nickel powder, reduced nickel powder and atomized nickel powder.
1. It has a wide range of uses in different fields. Electrolytic nickel powder and reduced nickel powder are the main raw materials of powder metallurgy. These powders are widely used in synthetic diamond tools, cemented carbide, electrometallurgy, machinery, energy and other industrial sectors. Atomized nickel powder is irregular in shape, mainly used for high specific gravity alloy, diamond diamond, special welding rod, surface coating and powder metallurgy parts.
2. nickel powder is controlled by its particle size and apparent density range. The combination of fine particle size, dendritic surface, high purity and unique shape enables a range of applications including high purity magnetic alloys, silver nickel electrical contacts, welding electrodes, anti-seize lubricants, friction parts, nickel catalysts, compacted ribbons and organonickel compounds.
Superalloys are iron, nickel, and cobalt-based metal materials, which can work for a long time at temperatures above 600 ° C and under certain stress, with excellent high temperature strength, good oxidation resistance and hot corrosion resistance, good fatigue performance, fracture toughness And other comprehensive properties, also known as "super alloy".If you are looking for a supplier of High temperature alloy powder with good quality and reasonable price, Guangzhou Sailong Additive Manufacturing Co., Ltd. is a good choice.
