Drawn Aluminium Tube/Profiles

 

Drawn Aluminium Tubes/Profiles Introduction

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

 

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

 

CHAL Aluminium Corporation is a fully integrated aluminium company that provides all kinds of aluminium 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 producing of high precision aluminium drawn tube and profile. We have advanced equipment, adopt advanced extrusion and drawing technology, CHAL is committed to providing innovative aluminium solutions with higher performance, better quality, and valued fabrication service.

Manufacturing Procedures

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 aluminium bar by ourselves, and detect each batch, ensure that the aluminium 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 aluminium tubes.

● Annealing: through annealing, the tube will get better elongation and better bending performance.
