Hole wall pull away test for PCBs

2004

We are manufacturer of PCBs. As one of the reliability test to PCBs we would like to conduct PTH barrel pull test (Hole wall pull away test). Could anybody suggest the wire used for this test? If we use the copper wire, it breaks very fast. Somebody told that best wire is steel alloy with solderable surface.

Where it is available? Source? Please let me know if the details of test is required.

Thanks in advance,
