When it comes to etching metals, a number of options are
available. Options include the specific process used, and what
type of metal will be used. Each metal has its own unique and
individual properties. For example, stainless steel is an
incredibly hygienic metal. Often etching uses stainless steel,
aluminum, copper and brass amongst others. Brass is often chosen
because of its softness, and easily malleable qualities. Its
softness makes it valuable in instances where sparks should not
be struck or for tools and fittings where explosive gases might
be present. It has a yellowish color, similar to gold, and is
fairly tarnish resistant. Brass is an alloy of zinc and copper,
giving it many of the same properties those metals possess.
Since brass is so soft, it is able to be etched in shorter times
and with less mechanical force compared to other metals. It is
easily formed into strips, rods, tubes, sheets or plates that
can be engraved or etched. This metal is also one of the best
and most cost effective condu
