generation and transmission, heating and cooling systems, and
telecommunications equipment, ensuring that the metal remains a
crucial aspect of modern industrial life.

sterling silver and gold alloys. It may also be used on its own, or
as a constituent of brass, bronze, gilding metal and many other base
metal alloys.</p><p>Copper bars are typically minted to high levels
of purity and come in varying sizes. Typically, small bars are one
ounce in size, but mints also produce copper bullion bars in sizes as
large as 10 pounds.</p>
