The drawn tube process provides exceptional dimensional control and a superior surface finish. Drawing also enhances the bending, flaring and formability of tubing.

DRAWN TUBE
     It can be provided in coil or straight length configuration.

"Drawn tube" for most applications is a better material choice than "as extruded tube". Penn Aluminum is a premier drawn tube supplier.

Aluminum tubing are hollow extrusions that are symmetrical with uniform wall thickness except as affected by corner radii. Refer to Pipe and Tubing for the basics.

Drawn tube obtains its mechanical properties, characteristics, and dimensions by drawing "as extruded tube" through a die. In addition to adding strength, the drawing process provides exceptional dimensional control and a superior surface finish that would not be attainable in an extruded product of the same alloy and size. Drawing also enhances the bending, flaring and formability of tubing. Ovality can be controlled more precisely in the drawing process than in the extrusion process. Tempers for non-heat treatable alloys (3xxx series) are imparted through the drawing process (cold work/strain-hardened). The heat treatable alloys (6xxx Series) obtain their temper through heat treating at the conclusion of the drawing process.

Penn Aluminum has developed proprietary processes and practices to provide superior drawn tube to meet the end users applications. The quality of Penn Aluminum's products and services is managed, controlled, and assured by a registered ISO/TS 16949:2002 quality system.

A few of the many applications for drawn tubing are : automotive products, refrigeration lines, HVAC, heat transfer, fluid lines, furniture, lawn and garden, electronics, lighting, outdoor leisure sports, office automation, conveyors, and healthcare products.
