Aluminum alloy welding wire 5154 alloy aluminum wire

First, the weight is light, the density of aluminum is relatively small, and the use of aluminum wire is suitable for scenarios with weight requirements (such as aviation models). Second, good electrical conductivity, aluminum wire can be used in some power transmission scenarios where the requirements for electrical conductivity are not extremely high to help transport current. Third, corrosion resistance is strong, and its surface will form a dense oxide film, which can prevent the internal aluminum from being further corroded, so it can play a role in some wiring situations with a certain corrosive environment. Fourth, it has good ductility and is relatively easy to process into various shapes, such as bending and weaving into different shapes for decoration and other purposes.

The first is the weight, the density of aluminum wire is about 2.7g/cm³, and the density of steel wire is about 7.8g/cm³, and the aluminum wire is much lighter. Aluminum wire is more suitable for weight-sensitive applications, such as aerospace models or some equipment frames that require portable installation. The second is corrosion resistance, aluminum wire can form a dense alumina protective film in the air, prevent further oxidation, and perform better in a certain corrosive environment (such as humid environment). In contrast, steel wire is easy to rust and corrode without protective measures. In addition, aluminum wire conducts electricity better than steel wire. Although the electrical conductivity of aluminum is slightly worse than that of copper, it is much stronger than iron (the main component of steel wire), and in some cases, there are requirements for electrical conductivity and environmental conditions allow, aluminum wire can be used as a conductive material.
