Aluminum forging offers a number of outstanding advantages over other manufacturing processes such as sand casting. Properties of the aluminum alloy represent only the beginning of end-user benefits. The forging process adds superior mechanical and physical properties created by heat and pressure.
Among the key advantages:
1. Low specific weight which is why fuel costs resulting from a lower weight of vehicles, vessels, planes, etc. can be reduced.
2. Resistance to atmospheric agents (because aluminium products are not subject to corrosion which reduces restoration costs).
3. Excellent electrical conductivity (aluminium and its alloys constitute the only useful material for the transmission of high-voltage power).
4. Specific mechanical properties facilitate relatively good shaping and reshaping thereof.
5. Safe material in terms of health.
6. Can be recycled and subsequently reused.
7. Long lifespan.
