Sažetak
The paper examines the influence of vacuum on the occurrence of porosity during casting of aluminum alloys. Porosity belongs to one of the main factors regarding quality of the products in casting industry. Porosity cause casting defects, have negative influence on quality of casting and decrease usability of castings in respect of reduction of their tensile strength, material fatigue and impact resistance which influences directly density of the casting itself. Hydrogen as the only gas capable to solve in significant quantities in aluminum melt is the main factor influencing gas porosity.
