Drawn Aluminum Tube

Drawn Aluminum Tubes/Profiles Introduction

Precision-drawn aluminum tubes are the lightweight solution for standard heat exchangers manufactured with mechanically expanded round tubes, flat oval tubes, and other shapes of the tube as customized specifications.

The high-precision drawn aluminum tube (also called aluminum cold drawn tube) is widely used for heat exchangers, including aluminum round tube, internal thread tube (inner grooved tube), seamless collector tube (header pipe), old drawn aluminium tube, seamless drawn aluminum tube, capillary tube, peanut tube, etc. It is the key material for terminal products, such as home and commercial air conditioning evaporators and condensers, automobile air conditioning evaporators, radiator condensers, water tanks, etc.

CHAL Aluminium Corporation is a fully integrated aluminum company that provides all kinds of aluminum products and technical solutions. The extrusion and drawn tube project started in 1998, CHAL is a high-tech enterprise specializing in the R&D and production of high precision aluminium drawn tube and profiles. We have advanced equipment, and adopt advanced extrusion and drawing technology, CHAL is committed to providing innovative aluminum solutions with higher performance, better quality, and valued fabrication service.

Manufacturing Procedures of Drawn Aluminum Tube

The manufacturing operation includes extrusion, cold drawing, zinc coating, and heat treatment(annealing), finishing dimension forming, degreasing and cleaning.

Quality Control

To get good quality, we must strictly control each step. 

  • Raw material: we produce aluminum bars by ourselves, and detect each batch, ensuring that the aluminum bar is pure, free of impurities, and the chemical composition meets customer requirements.
  • Drawing and tooling: the importance of tooling is to ensure dimensional accuracy, through cold drawing to get high precision of dimension and tolerance. 
  • Zinc coating: the tube with zinc spraying can greatly improve the corrosion resistance of aluminum tubes.
  • Annealing: through annealing, the tube will get better elongation and better bending performance.
