Lead has been used for many centuries for weighting purposes. Apart
from its high density, which enables smaller volumes to be used to
provide desired weights, the main advantage of Lead is its
durability. This is particularly relevant in aqueous and marine
environments, such as weights for fishing lines and anchors, because
iron - itself fairly dense - rapidly corrodes in such environments,
unless large additions of alloying materials are used or the weight
is covered with a protective coating. Small Lead weights are now
banned for hunting and fishing in certain areas because of the risk
of birds ingesting them.Larger weights are still permitted, as
are other uses such as in diving belts. Lead weights are also found
in many other applications including wheel balances on motor cars,
curtain weights and yacht keels.

Suitability for Recycling
- As with other metallic
applications, Lead weights can easily be recycled. In practice, the
degree of recycling depends on the ease with which the weights can
be collected.
