Abstract
Aluminium has contributed
very significantly in its development as a versatile metal. Because of unique
characteristics, aluminium has substituted much older and established materials
like wood, copper, iron, and steel. On volumetric basis, more aluminium is
consumed than all other non-ferrous metals including copper and its alloys as
well as lead, tin, and zinc. Aluminium has achieved this position in spite of
the fact that its commercial production began only towards the end of the
19thcentury, and thus aluminium
was a latecomer to the industry. The present work mainly focuses on the
mechanical strength of the alloy Al7068 with Mg% and Zn% variation in
composition. The compression behaviour and hardness of the aluminium alloy Al7068
by varying the Magnesium and Zinc composition was studied in this research
work. Compression behaviour and hardness of the material are studied for Mg
variation (2.2 to 3%) and Zn variation (7.3 to 8.3%) individually. These
specimens were first machined to ASTM standard size and then the experiment was
conducted for the required parameters. The results show that low strain was
obtained for the Mg composition of 2.5% and Zn composition of 7.6%, whereas the
highest hardness of the material was achieved at 3% Mg and 8% Zn compositions.
