3103 H14 Cold Drawing Extruded Aluminium Tube Is Used For 0.35mm With Outer Diameter Of 12.5mm

The Art of Aluminum Tube Cold Drawing: Boosting Tube Quality & Dimensionality
The aluminum tube cold drawing process expertly fabricates aluminium rods to exact specifications. Each cold drawing step compacts the rod's cross-section, ensuring superior surface finish and precise dimensions. Valued for its ability to produce top-notch aluminium alloy tubes, this methodology finds substantial application across various industries like aviation, automobile, rail transit, electronics among others.

Discovering the Steps to Cold Drawing in Aluminum Tube Fabrication.
For our understanding, cold drawing of aluminum tubes involves a systematic sequence - choosing suitable rodstock, pre-treatments, starting the first draw, drying, executing mid-draws, undergoing hot treatments, performing final draws, rectifying, preparing for pickle and performing cold processing. Initially, we will position the aluminum rod onto the machine for the initial draw to initiate deformation. Mid-draw is intended to mold the steel bar in the center to acquire an ideal shape dimension for the tubing. Lastly, the last deep draw aims at refining burrs on the tube, heightening both surface quality and dimensional precision.

The cold extrusion method employed on our aluminium tubes offers several advantages:
1. Excellent Precision: The aluminium alloy tubing's cold drawing technique achieves a surface flatness of less than 0.02 millimeters and dimensional accuracy around 0.05 millimeters.;
2. Complex Shapes Created Easily: The aluminium tube cold drawing process unlocks the ability to craft diverse intricate shapes, including non-uniform and thin walled tubes;
3. Improved Aesthetic Quality: This cold drawn aluminium tube process significantly diminishes surface burrs, heightening its overall visual appeal.

The underscored process of cold drawing aluminum tubes produces superior caliber, sophisticated aluminum alloy tubes for numerous sectors such as:
1. Aviation industry: Building aircrafts, rockets, and high-speed vehicles;
2. Transportation sphere: Employing aluminum alloys in automobiles, trains, subways, etc.;
3. Electronic world: Packaging electronic products and crafting conductive pipes, just to name a few.

【 Conclusion 】

The Advantages and Market Prospects of the Aluminum Tube Cold Drawing Process: Cold drawing process of aluminum tube is an essential method for fabricating high-precision aluminum tubes. This process demonstrates high attributes, superior surface smoothness, precise size precision and minimal machining burr of aluminum tubes, rendering it advantageous in diverse industries such as aviation, automotive, rail transit, electronics, and so forth.
