Meteoric iron used for keris's vs. for Indian weapons

[okhba3]

According to an Indonesian book: "Pamor Keris" by Bambang Harsrinuksmo, the key component for Pamor is Titanium and not Nickel. It's true that there was a laboratorium test for Prambanan meteorite and it said that there were 4.7% Nickel, 49.38% Iron and 0.53% Phospor, but the test was using ancient chemical anlysis. A newer test using nuclear physics was done by Haryono Arumbinang reveals that there was no Nickel in Prambanan meteorite, instead there were significant amount of Titanium, Iron, Zirkonium and Niobium.
The logic behind it that Titanium is so hard that when the meteorite hits the earth, most of the material was burned except for Titanium and other metals.
