The Leading Role of Aluminium in the Growing Production of Castings Made of the Non-Ferrous Alloys

The paper presents changes in the production volume of castings made of non -ferrous alloys on the background of changes in total production of casting over the 2000-2019 period, both on a global scale and in Poland.It was found that the dynamics of increase in the production volume of castings made of non-ferrous alloys was distinctly greater than the dynamics of increase in the total production volume of castings over the considered period of time.Insofar as the share of production of the non -ferrous castings in the total production of castings was less than 16% during the first two years of the considered period, it reached the level of 20% in the last four years analysed.This share, when it comes to Poland, increased even to the greater degree; it grew from about 10% of domestic production of castings to over 33% within the regarded 2000-2019 period.The greatest average annual growth rate of production, both on a global scale and in Poland, was recorded for aluminium alloys as compared with other basic non -ferrous alloys.This growth rate for all the world was 4.08%, and for Poland 10.6% over the 2000-2019 period.The value of the average annual growth rate of the production of aluminium castings in Poland was close to the results achieved by China (12%), India (10.3%) and the South Korea (15.4%) over the same period of time.In 2019, the total production of castings in the world was equal to about 109 million tonnes, including over 21 million tonnes of castings made of non-ferrous alloys.The corresponding data with respect to Poland are about 1 million tonnes and about 350 thousand tonnes, respectively.In the same year, the production of castings made of aluminium alloys was equal to about 17.2 million tonnes in the world, and about 340 thousand tonnes in Poland.
