Aluminium is a material that is very popular in many industries. It is light, stable and has excellent thermal and electrical conductivity. On the other hand, aluminium is a sustainable material that is 100% recyclable. Aluminium components are ideal for the production of heat sinks, heat exchangers and cables and have countless applications in electronics and electrical engineering.
