Cast copper sculpture is the works fabricated with casting technique of a predetermined form, size and performance obtained when metal is smelt into the required liquid that is poured into the casting mould, cooled, solidified and cleared.   

The history of cast copper is very long with mature technique. Cast copper craft is more complex than that of forge copper with better restorability of artistic creation. Therefore it is suitable for materials made into exquisite works and figure stature is the most common in particular.

Firstly, copper has a long life, regarded among the perpetual materials, not easy for efflorescence and corrosion (certainly some verdigris will be produced, but it is much better than steel as the rusting will not be too serious); 

Secondly, as a metal material, copper has good elasticity and strong toughness, available for supporting large volumes with few support points.

Thirdly, the fabricated cast copper sculpture is hollow to control the weight effectively. Especially while the top-heavy works are fabricated with serious deviation of the center from the supporting points, the top could be made thin to the greatest extent with the bottom so thick as to adjust the centre-of-gravity position for more fastness etc., compared with other materials. 

There are quite a lot of advantages for cast copper yet with some faults. Each has its own merits when compared with other materials.
