Aluminum skimmings
It is said that the Polish aluminum skimmings collector for a specific subculture. Before proceeding to the characteristics of this group, formed by the unemployed, we discuss the properties of materials collected by them. Scum of aluminum due to the typical non-ferrous metals, which results from high plasticity, belongs to a group of light metals, has a good conduction of heat and electricity and is resistant to corrosion (on exposure to air include metal oxides, protection korodowaniem), and many acids and bases action. These advantages in such a way that is commonly used in transportation and aerospace, electrical. Manufacture of aluminum dregs of weight due to the use of metal. In addition to these industries, scum arise in the chemical industry, skimmings where the A199, 995R is used in the manufacture of chemical apparatus and condenser film an d other varieties in the food industry to distribute aluminiowania steel and many everyday objects. Scum outstanding hardness and strength arise after the iron enrichment of aluminum, silicon, zinc, tin and titanium. Rich in content elements, scum are valuable as a secondary raw material, and hence its market price in companies engaged in collecting and processing scrap metal. And scum popular among people professionally lazy and poor. Plastics processing (carried out in hot or cold) consists of a rolled sheet or aluminum foil, bench press bars, tubes, pipes and fittings. Since pure aluminum is relatively small forces, is transformed primarily those who can assess (with the exception of Noteworthy for the last course, which is alumilat). Despite the low fatigue strength are valuable, so useful design parameters that make it their strength did not decrease the reduction temperature and is higher than for steel.
