The 5083 H111 seamless aluminum tube tubing is a high-magnesium alloy tube with good strength, good corrosion resistance, and machinability in non-heat treatable alloys. The surface is beautiful after anodizing. The arc welding performance is good. The main alloying element in 5083 alloy is magnesium, which has good corrosion resistance and weldability, as well as medium strength. The excellent corrosion resistance makes the 5083 alloy widely used in maritime applications such as ships, as well as automotive, aircraft welding parts, subway light rail, pressure vessels that require strict fire protection (such as liquid tank trucks, refrigerated trucks, refrigerated containers), refrigeration devices, TV towers, Drilling equipment, transportation equipment, missile parts, armor, etc.

The production process of 5083 H111 seamless aluminum tube tubing  

1.1. Hot-rolled 5083 H111 seamless aluminum tube tubing are generally produced on automatic tube rolling units. After inspection and removal of surface defects, the solid tube blank is cut to the required length, centered on the end surface of the perforated end of the tube blank, and then sent to the heating furnace for heating and perforated on the piercer. While the piercing is continuously rotating and advancing, under the action of the roller and the plug, a cavity is gradually formed inside the tube blank, called a capillary tube. And then sent to the automatic tube rolling machine to continue rolling. After zui, the wall thickness of the whole machine is adjusted, and the diameter is determined by the sizing machine to meet the specifications. It is a more advanced method to produce hot-rolled 5083 seamless pipes using a continuous pipe rolling unit.
1.2 If you want to obtain 5083 H111 seamless aluminum tube tubing with smaller size and better quality, you must use cold rolling, cold drawing or a combination of the two. Cold rolling is usually carried out on a two-roll mill. The steel pipe is rolled in a circular pass composed of a variable-section round hole groove and a fixed conical head. Cold drawing is usually carried out on a single-chain or double-chain cold drawing machine of 0.5-100T.
1.3. The extrusion method is to put the heated tube blank in a closed extrusion cylinder. The perforated rod and the extrusion rod move together so that the extrusion is extruded from the smaller die hole. This method can produce 5083 H111 seamless aluminum tube tubing with smaller diameters.
