This pipe is made from a 7000 series aluminium alloy and formed by cold drawing, which pulls the metal through a die at room temperature rather than pressing it out hot. The result is a straight, small diameter tube with an even outside profile and a consistent wall along its length. Cold drawing works the metal rather than only shaping it, so the tube keeps a clean surface and regular dimensions, which matters when it has to slide into a fitting or be joined end to end with other parts.
The 7000 series family is one of the stronger aluminium alloy groups, so a pipe made from it can carry a load while staying far lighter than a comparable steel tube. That balance is why it is chosen for tubular parts that have to move, be carried, or be mounted on a structure that cannot afford extra weight.
The pipe can be supplied as a formed part rather than a plain length. Bending turns the straight tube into a shaped run that follows the line of a frame, a handle or a support, while welding closes joints, adds fittings, or joins the pipe to another component. Working from a cold drawn starting tube means the bend stays true to the planned angle and the welded joint is not fighting a warped section. Parts that would otherwise be cut and joined from several short pieces can often be produced as one continuous shape.
A protective surface treatment is applied to the finished pipe to limit scratching and corrosion. Handling, stacking and shipping all expose bare aluminium to marks and to the moisture that starts surface oxidation, so the treatment keeps the tube in good condition until it reaches the assembly line. The treated surface also gives the part a more uniform look.
Because the pipe is offered with bending and welding services, the finished part can follow the drawing or sample the buyer supplies. Lengths, bend positions and welded assemblies are handled as one job, so the pipe arrives as a component rather than a raw length still to be cut and joined in house.
