Metal technology has long been developing

Kris made by forging technique, not casted. Accompanied by folding and forging techniques are useful to search for purity iron, which at that time iron materials are composites with other natural materials.

Kris was the beginning of sheet metal folded up sometimes up to a thousand times fold will likely still be worth a process that is unique, interesting and difficult. Development of technology capable of forging the forging techniques to create a Tosan Aji (Tosan = iron, Aji = value).

Elections will stone meteorites that contain titanium as a material element of the keris, is also an invention of our ancestors are awesome. Titanium is better known as the best material to make the dagger because it is lightweight yet very strong.

Difficulty in making keris of titanium materials is the melting point to 60 thousand degrees Celsius, far from the melting point of iron, steel or nickel in the range of 10 thousand degrees Celsius.

Titanium proved to have many advantages over other types of metal elements. The element titanium is hard, strong, lightweight, heat resistant, and corrosion resistant.
