Copper, symbolized as Cu with atomic number 29, is a versatile transition metal known for its distinctive reddish-orange color and excellent electrical conductivity. Constituting about 0.0068% of the Earth’s crust, copper ranks as the 26th most abundant element. While not as prevalent as aluminum, copper plays a crucial role in various industries. In its pure form, copper is malleable and ductile, and its utility is further enhanced when alloyed with elements like zinc, tin, nickel, forming alloys with diverse properties.
Copper ores, such as chalcopyrite and bornite, serve as primary sources, and the extraction process contributes to its availability. Copper alloys, created through amalgamation with other elements, offer enhanced strength and corrosion resistance. Its versatility makes copper indispensable in applications such as electrical wiring, plumbing, construction, and various industrial processes. Despite its lower abundance compared to aluminum, copper’s unique properties and alloys make it an indispensable metal in the modern world.
Alternators are composed of mixed automobile alternators, devoid of large attachments. Used in cars and trucks to power the electrical system and charge the battery, alternators hold scrap metal value due to components like interior wound copper wire, aluminum casing, and other metals used in their manufacture.
Starters encompass mixed automotive starters, free of large attachments. Commonly found in cars, trucks, and other vehicles, starters possess scrap metal value owing to their interior copper wiring, making them valuable in the recycling process.
Copper Transformers consist of mixed transformers, free of aluminum windings and other attachments. Found in various devices like power supplies, microwaves, circuit boards, and construction sites, transformers hold scrap metal value due to their copper windings.
Sealed Units comprise whole steel-cased compressors from air conditioner units, freezers, refrigerators, etc., containing an internal motor. These units must be free of hazardous materials, including chlorofluorocarbons (CFCs) or other refrigerants and polychlorinated biphenyls (PCBs). Loose iron or extra attachments like frameworks are not permitted.
Copper Ballast includes whole and complete fluorescent light ballasts containing copper. Must not contain polychlorinated biphenyls (PCBs), with specifications subject to agreement between buyer and seller, particularly regarding electronic ballasts.
Electric Motors are sized to approximately basketball size or smaller and consist of whole electric motors and/or dismantled electric motor parts, primarily copper-wound. They may contain some aluminum-wound material, subject to agreement between buyer and seller. Excessive steel attachments like gear reducers, iron bases, pumps, or loose free iron are not allowed. Sealed units or cast iron compressors are not included in this specification.
