Products of Metals Alloyed
Aluminium Symbol Al: Most abundant metal in earth’s crust. Pure aluminium is a light, silvery metal. The metal melts at 660 °C, boils at 2,467 °C and has a density of 2.7. Objects made of aluminium are corrosion-resistant.
Lead Symbol Pb: Bluish grey metallic element, metallic lead is soft, very ductile and is a poor electrical conductor. A newly cut lead surface has a light, silvery shine which quickly turns to the characteristic bluish grey colour. The heavy metal melts at 328 °C and boils at 1,740 °C.
Chromium Symbol Cr: Is mainly used for refining steel. It is a silvery white, brightly shining metal which is tough, ductile and malleable. It has a melting point of 1,857 °C. Chromium is resistant to corrosion.
Cr- Ni scrap V2A: Cr-Ni steel scrap of 18Cr/8Ni grade, resistant to rust and heat. It mainly occurs in the cutlery, foodstuffs and household appliances industries.
Cr – Ni – Mo scrap V4A: Cr-Ni-Mo steel scrap of 18Cr/10Ni/2Mo grade, resistant to rust and acid. It occurs in the chemical industry.
Electric motors: All kinds of old motors which no longer work. They generally consist of copper coils and an ferrous core.
Cables Copper and aluminium cables: From demolition sites, manufacturing processes and electronic scrap recycling.
Copper Symbol Cu: Is one of the non-ferrous metals. Copper occurs in nature not only in the form of compounds (e.g. in sulphide ores), but also in its pure form (native). The pure metal melts at approx. 1,083 °C and boils at approx. 2,567 °C. The relative density of copper is roughly 8.9; copper is a good electrical conductor and is suitable as a heat exchanger.
Brass: An alloy of copper (Cu) and zinc (Zn), hard but nevertheless ductile metal.
Red brass: Alloy of copper (Cu), tin (Sn), zinc (Zn) and lead (Pb) which is mainly used in the plumbing trade and mechanical engineering.
Zinc Symbol Zn: Metallic element, shining white metal with bluish grey lustre. Zinc plays an important role in industry in many respects. Brass, a zinc-copper alloy, and various zinc pigments used as corrosion inhibitors are just a few examples. Pure zinc melts at approx. 420 °C and boils at approx. 907 °C
