- - - - examples includes: brass (copper and zinc), stainless steel (iron, carbon and other metals) & bronze (copper and tin).
        
        the atoms of another element have a different size, this foreign atom distrusts the orderly arrangement of the metal ions and thus, prevent the layers of the metal ions from sidling over one another easily. this strengthens the metal.
- - - - about 90% of the metal ore is used for extraction turns out to be waste. with such a decrease in mining for ores, the land would be freed up for other uses such as agriculture. if metals are recycled and reused, there will be less need to dig for metal ores. air and water pollution will also greatly reduced.
    - - fewer landfills will be required to dispose of both used metal objects and waste material from metal extraction. this will help save on the cost of building landfill sites.
    - - extraction of metals from their ores requires a continuous supply of energy. by recycling our metals, we can also conserve our limited fossil fuels.
