How Does Bismuth's Lone Pair Effect its Properties as a Metal and Alloy?

Bismuth is really the only metal to exhibit a lone pair in its outermost shell, this means that it and it's salts should be a lewis base. As bismuth can act as a lewis base, how does this affect its properties as a metal specifically in regards to alloying. For instance, if I have a 1:1 mol ratio of aluminum and bismuth in a alloy, will the aluminum and bismuth form dative bonds?
