Aluminum is one of the most common metals in the world. We can precisely machine aluminum into a variety of shapes.
Characteristics of aluminum
Aluminum is one of the lighter metals, lighter than steel. The demand of aluminum is continuing to increase in products that require lightweight construction, such as trains and automobiles. Aluminum also has a strong oxide film on its surface, making it resistant to corrosion. Furthermore, plating can be applied to improve durability. Aluminum has low processing hardness and a low linear expansion coefficient, making it one of the most suitable materials for precision machining. Aluminum is non-magnetic and not affected by magnetic fields, so it is used in compasses and other products. Aluminum has three times the thermal conductivity of steel. On the other hand, it also has the ability to cool quickly. That is why it is used in radiators and air conditioners. Compared to other metals, it is largely available and low inventory risk, making it an easy-to-obtain, inexpensive material.
