It is estimated that about 75% of billion tons of aluminium produced so far is still used. Production of aluminium has increased four times over the last 40 years. Aluminium is a material that can be recycled several times whereas its properties remain the same.
Recycling of aluminium considerably saves energy: 95% less energy is used for remelting of aluminium scrap than for production of primary aluminium.
Production of secondary aluminium casting alloys includes remelting of specific kinds of scrap, raw materials and their modification to achieve a target chemical structure of the alloy. Such product in the form of ingots or liquid metal delivered to a customer is a finished product used for production of the high quality aluminium components.
CASTING (SEMI-FINISHED PRODUCT)
Engine heads and blocks, gear boxes, pistons, gears or pumps in automotive industry; components and parts in mechanical and electrical industry; castings for production of domestic appliances and many other in building industry are the main applications of the secondary aluminium casting alloys.
A CAR (FINAL PRODUCT)
For the first time aluminium was used over 100 years ago. Currently, a passenger car includes about 150 kg of aluminium components in average, whereas the share of aluminium in the car production is constantly growing. Through increasing number of aluminium components applied in cars, a car becomes lighter and in consequence it becomes more economic, which helps to reduce CO2 emission.
Nowadays, it is hard to imagine our life without aluminium. Life cycle of aluminium components varies from a few weeks for products such as aluminium cans through 20 years for automotive products to almost 30-40 years for components used in building industry. After that time and upon undergoing the recycling process these products begin their new life cycle.
