Mercury metal (from latin hydrargyrum = liquid silver) is shiny and silvery and the only metal that is liquid at room temperature. Mercury metal is known since ancient times, when it was believed to be something magical and also a cure for everything. More recently Mercury metal was and still is used in thermometers and barometers and in amalgams as filling for our teeth. Elemental mercury and many of its compounds are very toxic, so it should be avoided and not be used, if there are alternatives. Mercury metal can be sold only in small quantities and perfectly sealed for laboratory or display use.

Cobalt powder is gray and irregular, soluble in acid, magnetic, easy to oxidize in wet air. It is widely used in aviation, aerospace, electrical, mechanical manufacturing, chemical and ceramic industries. Cobalt based alloys or cobalt containing alloy steels are used as high temperature heat-resistant parts and important metal materials in atomic energy industry as blades, impeller, conduit, jet engine, rocket engine, missile component and chemical equipment of turbine. As a binder in powder metallurgy, cobalt can ensure the toughness of the hard alloy. Magnetic alloys are indispensable materials in modern electronics and mechanical and electrical industries, which are used to make various components of sound, light, electricity and magnetic materials. Cobalt is also an important part of permanent magnetic alloys. In chemical industry, cobalt isused in high alloy and anticorrosive alloy, and also used in colored glass, pigment, enamel, catalyst and desiccant. Application -Water atomized cobalt powder has a relatively coarse grain size, which can be used in welding materials to improve its toughness, impact resistance and wear resistance. -Reduced cobalt powder is in fine size and high purity, can be widely used in diamond tools, powder metallurgy,

* A214 is a steel grade produced according to American ASTM standards, which belongs to American standard. * Now the common round steel processes are hot rolling, forging and cold drawing. The steel quality and application scope of these three processing modes will also have some differences. For example, the specification of hot rolling is generally 5.5-250MM, and the appropriate steel can be selected according to the actual needs. * Generally, parts are manufactured by machinery or used as seamless steel pipe blanks, and steel is also used in some building construction. Round steel has relatively high strength, high hardenability and very good toughness, so its pressure bearing capacity is also guaranteed. Even if it is used at high temperature, the creep strength is high and the durability is also guaranteed.
