aluminum casting:
create the mold
(pattern is pushed into chemically binded sand)
leaving the
impression of the part to be casted.
the
molten aluminum is poured into the mold
and allowed to cool and harden/solidify
the mold is pulled apart, out comes the desired part!
billet aluminum:
solid block
of aluminum (size depending on desired part)
Contrary to casting, billet parts are created by removing excess material from
the billet,
essentially the part is carved out of solid aluminum.
billet Advantages:
-Cost effective in
low quantities
-High degree of
precision
-Very short lead
times
-Structurally the
parts are stronger
billet Disadvantages:
-Costs increase as
quantities increase
-Some designs are
not cost effective to machine
-Some designs
cannot be machined from solid billet
Casting Advantages:
-Cost effective at
low quantities
-Can produce parts
of all sizes
-Capable of
producing uniquely shaped parts
Casting Disadvantages.:
-Labor intensive
-Reduced
dimensional accuracy compared to billet
-Rough surface
finish
-Imperfections or
defects in the metal
Hot rolled steel is cheaper than cold rolled,
because cold rolled is basically hot rolled plus some extra processing
Hot rolled will not be made a precisely as cold rolled
but for many applications, hot rolled is good enough
“Hot Roll” is the nickname
for steel that has been produced in the “hot rolling” method,
processed at temps >
recrystallization temp of the material.
Well-priced/popular
where finished surface quality is not critical.
"Cold Roll” is the
nickname for steel that is produced in the “cold rolling” method,
processed near room
temps. Limited to a few shapes, but many finishes.
Offers superior
strength and machinability.

decorative, mechanical and architectural applications.
alloy made
of copper and zinc, good for visually appealing or low friction, such
as fittings and tools.
Bronze metal has wide range
of alloys/purposes (from bearings to architecture and marine applications)
great choice for
strength, corrosion resistance and electrical conductivity.
primarily an alloy
of copper and tin, but can also be made with other additives, such as
aluminum.
Nickel metal and the alloys
made with nickel are among the strongest structural materials available,
including superior
performance in elevated temperatures.
high corrosion
resistance, used in aerospace & marine, and other machined parts.
Titanium metal is the top
material of choice in the aerospace industry
due to its high
strength-to-weight ratio, and extreme temperature and corrosion
resistance.
used in marine &
artistic implementations as well, making it an extremely versatile material.
Stainless steel metal is a
versatile material for corrosion resistance, strength, good pricing, + many
shapes.
generally formable and
weldable, good for structural/design applications (including Backsplashes).
Beryllium copper metal
is a unique material, looks like brass
high strength,
non-magnetic, non-sparking, so good for hazardous environments & aerospace.
Copper metal is known
and loved for its electrical conductivity and corrosion resistance.
Copper is
sought after by artists, machinists and architects alike,
due to its beauty,
malleability, conductivity and machinability.
