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.

“Hot Roll” steel produced via “hot rolling” method at temps > recrystallization temp of the material.

  Limited to a few shapes, but many finishes. Offers superior strength and machinability.Brass metal is widely used in 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.
