The forging of aluminum or aluminum alloy is called aluminum forging.
Aluminum is a metal element, the element symbol is Al, which is a silver-white light metal. There is malleability. Commodities are often made into rods, flakes, foils, powders, ribbons and filaments. It can form an oxide film to prevent metal corrosion in humid air. Aluminum powder can burn violently when heated in the air and emit a dazzling white flame. It is easily soluble in dilute sulfuric acid, nitric acid, hydrochloric acid, sodium hydroxide and potassium hydroxide solution, but hardly soluble in water. The relative density is 2.70. Melting point is 660°C. The boiling point is 2327°C. The content of aluminum in the earth's crust is second only to oxygen, ranking third, and it is the most abundant metal element in the earth's crust. The development of the three important industries of aviation, construction, and automobile requires the characteristics of materials to have the unique properties of aluminum and its alloys, which greatly facilitates the production and application of this new metal aluminum. The application is extremely wide.
Aluminum alloy is an alloy based on aluminum and added a certain amount of other alloying elements, which is one of the light metal materials.
Because forging technology has technical advantages that other production methods cannot match, it compensates for the gaps left in the casting process and other defects. The crystals in the metal become fine and compact, which makes the parts have more advantages in the high-pressure fatigue working environment in use. Long service life. This also makes the use of forgings very extensive, aircraft, automobiles, diesel engines, weapons, petrochemicals, mining and other aspects are applied to forgings.
There are many applications for forgings in many precision mechanical parts. For example, the proportion of forgings used in airplanes is very high, and up to 85% of aircraft components are forgings. Most of the main parts of the aircraft engine, the ribs of the fuselage, the landing gear and other important parts are obtained after forging. There are also many forging parts on automobiles, which have the common characteristics of light weight, poor working conditions, complex appearance, and high safety requirements.
