"Metal Die Cast" is made of all iron, most of which are Japanese series of robot toys. Its originator is the Japanese toy company Bandai (formerly known as "Popy"), which is derived from the material of "Invincible Iron King Kong". “Superalloy†is a trademark of the exclusive alloy of Bandai.
The Japanese toy company registered copyright for the word "superalloy" in the 1980s, so nowadays, other toys manufacturing companies use "alloy" toys in addition to the toys used in "Bandai" using the word "superalloy".
