Compared to metals,
alloys are stronger, harder, and have high resistance to corrosion. Alloy can
improve the different desirable characteristics of metals. Again, they would
not easily react to air or water unlike
the constituent metals. Steel, brass, amalgam,
solder, duralumin etc. are examples of alloys. With the desirable
characteristics which can be varied for different purposes and purposes, alloys
are used in wide range of applications. In most cases, they often replace metal
components in products. For example, compared to metal floats like copper
floats , stainless steel floats are recommended for usage in extreme conditions such as high pressure,
high temperature etc.
The stainless steel
floats are more durable and reliable as well. In fact, many float failures on
the float boxes, steam traps and float valves can be eliminated with use of
stainless steel. The rust free property
of most alloys especially stainless steel makes it the preferred material of
choice for flag pole balls. Alloys are at times economical options as well. For
example, metal balls which are rolling, spherical elements used to check in
ball valves, bearings and similar mechanical equipment are mostly made of
different grades of steel. Pricewise they are far more economical than ceramic
balls.
