Aluminum chemical symbol Al is the most abundant of the metals and is next in abundance to Oxygen and Silicon among the elements. Aluminum is non-magnetic, non-sparking, white in color and light in weight. Aluminum is used in the manufacturing of transportation equipment, building products, food and beverage packaging and is alloyed with silicon, manganese, magnesium, copper, zinc and iron to produce specification ingot, coil, plate and extrusion.
1100 Aluminum
Aluminum that is almost pure. It is normally in the form of wire but can be in sheets or plate.
6061 Aluminum
This material is used in transportation, irregation & structural applications.
6061 Wheels
Truck wheels are made out of 6061 alloy aluminum.
6063 Aluminum Extrusion
Typically found in window framing, door enclosures, thresholds and heat sinks. Bare marerial is valued more than painted.
7075 Aluminum
7075 is mainly used in aerospace applications, most airplane frames are made of this alloy because it has a high tolerance to bend without cracking.
MLC
This material has no coating and is a mix of several low copper aluminum alloys.
Painted Siding
This material is used for housing exteriors, gutters, down spouts, trailer siding, ect. Material must be free of iron and other contaminants.
Cast Aluminum
Cast aluminum is found in auto parts, gas grills, ornimental items. etc. Should be free of excessive iron.
Wheels
Automobile wheels should have the valve stem and wheel weight removed to be considered clean.
Clean Aluminum Copper Radiator…
Al/CU radiators are used in cooling and air conditioning equipment. These items are clean, meaning they have no iron ends.
Aluminum BX
BX is aluminum wrapped around 70% #1 copper wire. This is normally used in building applications.
Pollyfoil Dross
This is the slag from the process of adhering aluminum to plastic for packaging. Ever wondered why the inside of a potato chip bag is shiny? now you know!
Gas Meters
As the title states. These are gas meters used in commercial and residential settings. They comprise of cast aluminum, steel, plastic, and other metals.
Thermal Breakage
This is aluminum extrusion with a plastic strip in the middle. It is mostly used in door frames and windows to help with contraction and expansion of the joints.
Aluminum Turnings
Scraps of aluminum that has been turned, drilled or lathed.
Aluminum Foil
Examples include pie plates, cooking pans, and industrial aluminum foil.
CATV
This is the wire you see running from one power poll to another. It has a copper coated aluminum conductor in the middle, followed by foam, followed by and aluminum outer shell. It could also have black insulation on it. Then it would be called insulated CATV.
