Sustainability as Alumasa's foundation

Our commitment to sustainability is a fundamental part of our corporate culture. We are convinced that it is the best way to ensure the long-term success of our business.



Reduce greenhouse gas emissions


Recycle of scrap materials


Our raw material consists of aluminum waste compatible with our alloys. Soda cans, car license plates, car radiators, cables…

Continuous casting

Once we have controlled the alloy, we feed the continuous 04 casts with the alloyed metal to obtain aluminum coils with an average thickness of 6 mm.


Once we have the desired final thickness, we need to smooth or flatten the material to release any tension and achieve a flat and smooth surface suitable for painting.

Rotary Kilns

With a melting point of 750 degrees, we can melt aluminum waste, separating the other metals with higher melting temperatures from our metal. The result is impurity-free aluminum ready for alloying.

Cold rolling

With cold rolling, we reduce the thickness of our cast coils so that we can use them in the rest of the processes. The final thicknesses depend on the final application of the product, with the lowest thickness being 0.20 mm.

Coating and cutting

We paint the aluminum continuously through rollers with the 08 "coil coating" technique. Once lacquered, we cut it to the width required by the customer.

Melting Furnaces and Maintainers

In the melting furnaces, we can melt ingots, clean scraps, or recover liquid metal from the rotary furnace. Once we have the metal in this furnace, we verify the alloy and adjust the composition.


It is an intermediate step between rolling passes. It is a thermal process that softens the material since after several passes of rolling it hardens and becomes brittle.
