Aluminum - Used in transportation (automobiles), packaging, building/construction, electrical, machinery and other uses.
Copper - Used in building construction, electric and electronic products (cables and wires, switches, plumbing, heating); transportation equipment; roofing; chemical and pharmaceutical machinery; and alloys (brass, bronze and beryllium alloyed with copper are particularly vibration resistant); alloy castings; electroplated protective coatings and undercoats for nickel, chromium, zinc, etc. More recently copper is being used in medical equipment due to its anti-microbial properties.
Gold - Used in jewelry and arts; dentistry and medicine; in medallions and coins; in ingots as a store of value; for scientific and electronic instruments; as an electrolyte in the electroplating industry.
Lead - Used in lead-acid batteries, gasoline additives (now being eliminated) and tanks, and solders, seals or bearing; used in electrical and electronic applications; TV tubes and glass, construction, communications and protective coatings; in ballast or weights; ceramics or crystal glass; X-ray and gamma radiation shielding; soundproofing material in construction industry; and ammunition. Industrial type batteries are used as a source of uninteruptible power equipment for computer and telecommunications networks and mobile power.
Nickel - transportation, fabricated metal products, electrical equipment, petroleum and chemical industries, household appliances and industrial machinery.
