Drawn aluminum tube is a type of aluminum tubing that is made by drawing a solid aluminum billet through a die. This process is also known as cold drawing. The billet is first heated to a temperature that makes it soft and ductile. Then, it is drawn through a series of dies that reduce its diameter and increase its length. The final product is a tube with a smooth, uniform wall thickness. Drawn aluminum tube is available in a variety of sizes and shapes, and it is used in a wide range of applications.
How is Drawn Aluminum Tube Made?
The process of making a drawn aluminum tube can be divided into the following steps:
- Preparation: The aluminum billet is first prepared by cutting it to the desired length and removing any burrs or defects.
- Heating: The billet is then heated to a temperature that makes it soft and ductile. The exact temperature depends on the type of aluminum being used.
- Drawing: The heated billet is drawn through a series of dies that reduce its diameter and increase its length. The dies are made of a hard material, such as steel, and they are tapered so that the tube is drawn smoothly.
- Annealing: After the tube has been drawn, it is annealed to relieve the stresses that were created during the drawing process. Annealing is done by heating the tube to a lower temperature and then slowly cooling it.
- Finishing: The finished tube is then cut to the desired length and may be further processed, such as by bending, flattening, or threading.
What are the Benefits of Drawn Aluminum Tube?
Drawn aluminum tube has a number of benefits, including:
- Strength: Drawn aluminum tube is strong and durable. It can withstand a lot of stress without breaking or deforming.
