•It contains no heavy metals such as lead or cadmium, and brings no contamination to the environment.
•The light dead weight is convenient for transportation with low energy consumption.
•Its modular design with less utilization of welding process is able to reduce environmental pollution.
•Comparing with iron, aluminum is better in heat/electric conduction and has greater magnetic permeability, which means it has better heat dissipation effect and helps in releasing static electricity and avoiding magnetic disturbance.
•The melting point of aluminum is relatively low. As a result, it will bring little influence to the environment under recovery processing.
