(Restriction of Hazardous Substances) directive and sometimes it is a corporate directive. Some applications that fall under the RoHS directive are exempt from being lead-free because the reflow temperature requirements can only be met with high-lead solder alloys which are exempt under RoHS regulation

. Normally, this condition is 28-32 Rc (269-321 BHN) which gives good mechanical strength of around 100,000 psi (6,900 bar) tensile yield. It is still readily machinable in this condition
