Aluminum flat wire is also known as aluminum flat wire, flattened line, flat Angle wire or ultra-narrow strip, refers to the section of approximately rounded rectangle of the opposite sex wire, thickness from 0.025mm to 2mm, width is generally less than 5mm, the width ratio from 2:1 to 5:1, because the flat wire shape like ribbon, sometimes known as ultra-narrow flat strip. Compared with the common round wire, the form of aluminum flat wire has unique advantages in heat dissipation, welding contact area, resistance to fatigue, hardness control and so on. Below, a simple introduction to its production method.

The first thing to say is that the special-shaped die drawing method is similar to the production process of round wire. The rectangular special-shaped die is used for drawing, but this way can only produce aluminum flat wire with low width-to-thickness ratio, and is easy to cause uneven deformation or even fracture of the alloy wire, and can not produce high-precision and surface quality products.

At present, this method is the most common for aluminum flat wire. This process uses a slitting unit to cut strips of large width and obtain a narrow strip with a min width of about 3mm. The advantage of strip slitting process is that the processing difficulty is small and the processing cost is low in the case of large width, while the disadvantage is that the number and cost of cutting tools increase rapidly as the width decreases. As a result, it is not possible to produce ultra-narrow silk with a width less than 2mm. Another disadvantage is that the transverse tension in the process of cutting the knife and it is easy to cause sickle bending and wire twisting, which makes the product unqualified. In addition, the products obtained by the longitudinal shear method must be assembled by disk, and the market weight cannot be obtained by transverse winding.
