Our aluminum 90 degree elbows can be divided into: 1060 aluminum elbow, 6061 aluminum elbow, 6063 aluminum elbow, 6082 aluminum elbow, 5083 aluminum elbow according to the material. Aluminum 90 degree elbows are widely used in various industries, such as: automobiles, ships, aerospace, electrical appliances, agriculture, electromechanical, and so on.

The hardness of aluminum elbows of different alloy models is very different. For example, the hardness of the 6061 and 1060 aluminum elbows is very different. The 1060 aluminum elbow has moderate hardness and can adapt to common processing conditions, such as bending, while the 6061 aluminum elbow has a good hardness and is widely used in places with high hardness requirements.
The aluminum elbow we produce is a seamless aluminum elbow. The seamless aluminum elbow is made of seamless aluminum tube. It has the following advantages: hygienic, non-toxic, light weight, good heat resistance and good corrosion resistance. Good heat preservation, good impact resistance and long service life.

The seamless aluminum 90 degree elbows forming process has hot push, stamping, extrusion and the like.

Hot push forming
The hot-bending aluminum elbow forming process adopts a special elbow pushing machine, a core mold and a heating device, so that the blank placed on the mold moves forward under the push of the pusher, and is heated and bent during the movement. The deformation characteristic of the hot-rolled aluminum elbow is to determine the diameter of the tube blank according to the law of the volume change of the metal material before and after plastic deformation. The diameter of the tube blank used is smaller than the diameter of the elbow, and the deformation process of the billet is controlled by the core mold to make the inner arc portion,The flow of the compressed metal compensates for other portions that are thinned by the expansion of the diameter, thereby obtaining an aluminum elbow having a uniform wall thickness.

The hot-bending aluminum elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and suitable for mass production, and thus becomes the main forming method of carbon steel and alloy aluminum elbow.

The heating process of the forming process includes medium frequency or high frequency induction heating (the heating coil can be multi-turn or single turn), flame heating and reverberatory furnace heating, and the heating method is determined by the forming product requirements and energy conditions.

Stamping
Stamping forming elbow is the earliest forming process for mass production of seamless elbows. It has been replaced by hot push or other forming processes in the production of elbows of common specifications, but in some specifications of elbows due to the number of production Less, so the wall thickness is too thick or too thin.
The product is still in use when it has special requirements. The stamping of the aluminum elbow is performed by using a tube blank equal to the outer diameter of the elbow, and is directly press-formed in the mold using a press.

Before the stamping, the tube blank is placed on the lower mold, the inner core and the end mold are loaded into the tube blank, the upper mold is moved downward to start pressing, and the elbow is formed by the constraint of the outer mold and the support of the inner mold.

The aluminum 90 degree elbows manufactured by the inner and outer mold cold extrusion process has beautiful appearance, uniform wall thickness and small dimensional deviation, so the aluminum elbow, especially the thin-walled aluminum elbow forming, is mostly manufactured by this process. The precision of the inner and outer molds used in this process is high; the wall thickness deviation of the tube blank is also demanding.

We have rich experience in the production of aluminum elbows. The aluminum 90 degree elbows produced are sold at home and abroad. Compared with some low elasticity in the market, it is easy to break, easy to corrode, easy to rust, not resistant to high pressure and short in life. Elbow products, our products are durable and quality guaranteed, you can buy with confidence. If you want to know more, please call us or email us.([email protected])
