• We have studied the high-bias break of Sn nanocontacts at room temperature in ultrahigh vacuum. The distribution of the break conductance of Sn at high biases exhibits two peaks, contrary to the single broad peak observed for other metals. The positions of these peaks shift with the contact current, but not in proportion to the current, as is the case of other metals. At low biases, the two break conductance peaks merge into a single peak around $40G_{0}$, suggesting the intrinsic instability of Sn nanocontacts around this conductance.
