While these materials are common alloys in the microelectronics industry, Hi-Rel also has extensive experience supplying many additional alloys as well. So please let us know if you have a certain alloy in mind and don’t see it here.

Our lead times are short – 1-3 weeks are typical; and our quality is second to none – including solderability testing and third-party ICP analysis to confirm preform integrity.
