Nowadays, a transportation industry creates a lot of metal scrap because production and use of cars are on the increase worldwide. This is based on the fact that increase in the production of cars increases usage of aluminium alloys in transportation applications. Therefore, it is necessary to reduce the production of components from primary aluminium alloy and increase their replacement with secondary-recycledaluminium alloys because the production of recycled aluminium alloys is less expensive and less energy-intensive than the creation of new aluminium alloy through the electrolysis. In addition, the recycled aluminium alloys have comparable microstructural parameters and properties as the same primary aluminium alloys. RECYCLING UND EIGENSCHAFTEN VON SEKUNDÄRALUMINIUM LEGIERUNGEN FÜR VERKEHRSINDUSTRIE Zusammenfassung. Dank weltweiter Produktionserhöhung und Benutzung der Fahrzeuge produziert die Verkehrsindustrie heute viel Metallabfall. Wie steigert die Fahrzeugerzeugung, so steigert auch die Benutzung von Aluminiumlegierungen. Es ist nötig, die Produktion von Aluminiumprodukten aus Primäraluminium zu reduzieren. Die Produkte müssen also durch die Produkte aus Sekundäraluminium eingesetzt werden. Während die Schmelzflusselektrolyse bei der Gewinnung von Aluminium aus Bauxit 100 Prozent Energie verbraucht, sind es beim Recycling etwa vier bis sechs Prozent. Das Aluminium-Recycling leistet deshalb einen beträchtlichen Beitrag zur Einsparung von Energie, und dient damit gleichzeitig auch dem Umweltschutz. Noch dazu, die Legierungen vom Sekundäraluminium haben vergleichbare Eigenschaften wie dieselben Legierungen von Primäraluminium.

“…These materials are profitable for each industry field thanks to the costs, the high mechanical properties, the ductility, the good corrosion resistance etc. and so they can be used as replacements of steels and cast iron for the production of components (Eperješi et al, 2014;Uhríčik et al, 2014;Alfieria et al, 2015;Rosso et al, 2013;Rosso et al, 2014;Castella, 2015). Generally, these alloys contain high percentage of alloying elements that form a structural components.…”

The self-hardening aluminum alloys are interesting for producers of casting, because these materials have the required properties without using heat treatment. This casts production result in the following advantages: energy saving, reduction of the costs, no permanent deformation, largest casting dimensions possible, and so on. Nevertheless, it is well known that improvement of mechanical properties and structure of aluminum alloys can often significantly increase the lifetime of casting and reduce costs for fuel and reduction of environmental loading. The basic and energy saving method for improvement of mechanical properties of self-hardened alloys is surface hardening. Surface hardening improves properties such as: corrosion resistance, wear resistance and hardness. In regards this facts great interest in reducing the cost of components makes a great opportunity for use laser surface processing. Therefore this article deals with using laser surface heating and evaluations its influence onto mechanical properties of self-hardening ENAC-71100, i.e. AlZn10Si8Mg cast alloy. This alloy is especially used for engine and vehicle constructions, hydraulic unit and mound so the surface properties are important for application in industries. The results show that laser surface heating have influence on properties, but well defined conditions of heating are very important.

These days, a lot of metal scraps are generated by the automobile industry since the use of vehicles is increasing globally. As the production of automobile increases, the use of aluminum alloys has been increasing in automobile applications. Since the resources for the production of primary aluminum are getting scarce and the production of primary aluminum is highly expensive, production of components using secondary aluminum alloy in the form of scraps is highly essential. The present study deals with the re-melting of aluminium alloy scraps and the production of secondary aluminum alloy through a gravity die casting process. An investigation of its microstructure, chemical composition and mechanical properties such as hardness, tensile strength and an impact test have been performed and compared with the properties of primary and standard aluminum alloy. Porosity of secondary aluminum alloy is observed macroscopically. In addition a radiograph test was performed to study the internal defects of the secondary aluminum alloy.
