Process of shaping material by forcing it to flow through a shaped opening in a die.
Casting
Stamping
Forging
Extrusion
A ductile, malleable, reddish-brown metallic element that is an excellent conductor of heat and electricity.
Aluminum
Copper
Bronze
Brass
A ductile malleable, silver-white metallic element that is used in forming many hard, light alloys, often anodized for better corrosion resistance, color and surface hardness.
Copper
Brass
Aluminum
Lead
This aluminum finish is commonly referred to as anodized finishes, which are based on the specific ability of aluminum to develop a protective coating of oxide on its surface.
Organic finishes
Chemical finishes
Electrolytic Oxide finishes
Mechanical finishes
This kind of finish uses mechanical tools or equipment to obtain a wide range of finishes by grinding, polishing, scratching, sandblasting, embossing or other treatment of the surface to achieve a desired effect or to provide a base for other finishes.

Upon exposure to air and salt water, copper immediately reacts to form a surface layer of an insoluble green salt which retards further corrosion and this green color is known as (a)
A heavy, soft, malleable, bluish-gray metallic element used in solder and radiation shielding.
Copper
Lead
Brass
Bronze
Used for protective coatings or plating on stronger metals.
Zinc

Descriptive of a metal form obtained by rolling the metal while still hot; results in dark, oxidized, relatively rough surface.
(a)
Descriptive of a metal that has been formed by rolling at room temperature, usually to obtain desired form or improved surface finish or higher tensile strength.
(a)
A hot rolled structural steel section having a rectangular C shape with sloped inner flange surfaces.
