Castings Have Excellent Physical Properties

- Jul 20, 2017 -


The use of castings is very extensive, has been used in hardware and the entire machinery and electronics industry, and its use is becoming a growing trend. Concrete use, construction, hardware, equipment, engineering machinery and other large machinery, machine tools, ships, aerospace, automobiles, locomotives, electronics, computers, electrical appliances, lamps and other industries, many are ordinary people contact all day, Casting Parts but do not know the metal objects.

Castings are metal forming objects obtained from various casting methods, that is, the smelting of liquid metal, with pouring, injection, inhalation or other casting methods into the prepared mold, after cooling through the sand, cleaning and treatment, etc., the resulting in a certain shape, Casting Parts size and performance of the object.

Casting History:

Casting has a long history of application. Ancient people used castings for coins, sacrificial, weapons, tools and some living utensils. In modern times, castings are mainly used as blanks for machine parts, some precision castings can also be used directly as parts of machines. Castings in the mechanical products occupies a large proportion, such as tractor, casting weight about the total weight of the $number, Casting Parts agricultural machinery accounted for 40~70%, machine tools, internal combustion engines, such as Tatsu $number. All kinds of castings, the most mechanical castings, the most complex shape, the largest amount, about 60% of the total production of castings. The second is the metallurgical ingot mold and engineering pipeline.

Castings are also closely related to daily life. For example, the use of door-lock, door locks, radiators, water pipes, iron pans, gas stove racks, irons, etc., are castings.

Casting Category:

Castings have a variety of classification methods: According to the different metal materials used, it is divided into steel castings, cast iron parts, cast copper parts, cast aluminum parts, cast magnesium parts, cast zinc parts, titanium castings and so on. Each type of castings can be further divided into different types according to their chemical composition or metallographic structure. Casting Parts such as cast iron parts can be divided into gray iron parts, ductile iron parts, vermicular graphite cast iron parts, malleable cast iron parts, alloy castings, etc. according to the different casting molding method, the castings can be divided into ordinary sand-type castings, metal-type castings, die castings, centrifugal castings, continuous casting parts, investment castings, ceramic-type castings, Electroslag remelting castings, bimetal casting and so on. Among them, the most commonly used sand castings, about 80% of the total production. Aluminum, magnesium, zinc and other non-ferrous metal castings, mostly die castings.

Casting Performance and use:

Castings have excellent mechanical and physical properties, it can have a variety of different strength, hardness, toughness, combined with the comprehensive performance, Casting Parts but also a combination of a variety of special properties, such as wear resistance, high temperature and low temperature, corrosion resistance.

Casting weight and size range are very wide, the lightest weight of only a few grams, the heaviest can reach 400 tons, the wall thickness of the thinnest only 0.5 mm, the thickest can be more than 1 meters, the length can be a few millimeters to more than 10 meters, can meet the requirements of different industrial sectors.
