Plastic handle: Made of plastic as raw material, plastic is a synthetic polymer compound {polymer}, also known as polymer or macromolecule(macromolecules), also commonly known as plastics or resin, can freely change the shape of the body. The plastic handle is produced by the injection molding machine. The mold is designed according to the shape requirements. […]
Handle, refers to the handle, shake hands; the place where the object is taken up; mechanical parts. In the language of the “Three Kingdoms, Wei Zhi, Zhang Wei Chuan”: “Lun Buzhi Yuan Shao from Zhang Yang also, after leaving, parting, pledge.”
Introduction An alloy of other elements is added based on zinc. Commonly added alloying elements are aluminum, copper, magnesium, cadmium, lead, titanium, and the like. Zinc alloy has low melting point, good fluidity, easy fusion welding, brazing and plastic processing. It is resistant to corrosion in the atmosphere, and the residual waste is easy to […]
Introduction Pure copper is purple-red, so it is also called copper. It has excellent thermal conductivity and electrical conductivity. Its conductivity is second only to silver and second to metal. Copper has excellent chemical stability and corrosion resistance and is an excellent metal material for electricians. classification Copper alloys widely used in the industry include […]
Aluminum is a widely distributed element, which is second only to oxygen and silicon in the earth’s crust, and is the highest in metals. Pure aluminum has a low density of 2.7 g/cm3, good thermal conductivity and electrical conductivity (after Au, Ag, Cu), good ductility and high plasticity, and can be processed in various ways. […]
Ferrosilicon is made from coke, steel scrap, quartz (or silica) and smelted in an electric furnace. Silicon and oxygen are readily synthesized into silica. Therefore, ferrosilicon is often used in steelmaking as a deoxidizer, and at the same time, a large amount of heat is released during the generation of SIO2, and it is also […]
The pig iron is hard and brittle, but it is pressure and wear resistant. Gray iron and ductile iron. The carbon in white iron is silvery white with Fe3C fracture. It is hard and brittle and cannot be machined. It is the raw material for steel making, so it is also called steel pig iron. […]
Steel is an alloy of iron with C, Si, Mn, P, S and a small amount of other elements. In addition to Fe, the content of C plays a major role in the mechanical properties of steel, so it is collectively referred to as iron-carbon alloy. It is the most important and most used metal […]
All types of alloys have the following general characteristics: (1) Most alloys have a melting point lower than the melting point of any of the constituent metals of the composition; (2) The hardness is generally greater than the hardness of any of the components; (Special case: the sodium-potassium alloy is liquid, used for the thermal […]
(1) a mixture alloy (eutectic mixture), an alloy formed by crystallizing the components of the alloy when the liquid alloy is solidified, such as solder, cadmium-cadmium alloy, etc.; (2) a solid solution alloy, an alloy forming a solid solution when the liquid alloy solidifies, such as a gold-silver alloy; (3) An intermetallic compound, an alloy […]
