Copper
Copper is one of the most important industrial metals. 1982 was the last year copper was used to make pennies. Copper is used in electrical power cables, electrical equipment, automobile parts - mainly radiators, rooftops, cooling and refrigeration tubing, heat exchangers, artillery shell casings, water pipes, and jewelry data cables. Copper is an excellent conductor of electricity. Copper resists corrosion from the air, moisture and seawater.
Aluminum
Aluminium (Al), or aluminum, is a silver, soft metal that is present in more than 270 minerals. It is the most abundant mineral on Earth after oxygen and silicon.It's globally the most used metal that does not contain iron and is almost always used as an alloy, even if the aluminium content is as high as 99%. The most commonly used elements to combine with aluminium to create an alloy are zinc, copper, silicon, magnesium, and manganese.
Brass
The recycling process for brass requires less energy compared to aluminum and steel and yields a smallercarbon footprint. The ability to reuse brass from recycledmaterials makes it a unique metal. Brass has the capacity to be recycled an infinite number of times which is great for the environment. Since brass is a copper-based alloy, it does not lose its chemical or physical properties in the recycling process.
