It's a Furukawa proprietary material. 'Google' on just the 'EFTEC 64T'. [Sometimes it's Cu EFTEC 64T, copper EFTEC 64T, sometimes just EFTEC 64T.] For instance, Table 5-2 in: http://developer.intel.com/design/packtech/ch_05.pdf

I've been trying to find the metal composition of various lead frames. I keep reading about Cu-EFTEC 64T but can't find any info on it. Does anyone know what material this is?

Ah, here it is: EFTEC-64T. A commercial leadframe material with the nominal composition of Cu-0.3Cr-0.25Sn-0.2Zn
