LM2904: The test material of LM2904PWR

Tool/software:

Hi team

I checked the quality, reliability & packaging data of LM2904PWR in this link ti.com/quality-reliability-packaging-download/report?opn=LM2904PWR. 

But the Lead Frame information is blank here, could you please help check which material it is (TAMAC4 Cu7025 Cu194 TAMAC2)?

Thank you!
