The machining of aluminium is made from all kind of forms: bar, extrusión, casting of forging. It is material easy to machine. Its main property is the low density; therefore it is possible to produce light components with high grade of mechanical resistance.
It is specially important in cases where the weight is extremely vital, like as automotive, railway, aeronautic and industrial applications.
It presents good electrical properties, and permits the substitution for copper in some sectors. Also it is good termal conductor for applications where it is important the transmisión of heat or its dissipation.
Although its higher costs than the majority of steels, its low weight permits to compete in global costs and performance with Steel. Moreover the addition of other metals in its alloy achieve great improvement in its mechanical properties.
