Aluminum 7075
Aluminium 7075 best exemplifies an alloy that possesses exemplary strength, toughness, and fatigue resistance owing to its unique bulid with zinc is the composition. Put into perspective, it may not do as well in corrosive environments due to stress cracks which occurs more often in aluminium alloys. Regardless, the optimum strength to weight ratio enables it to be benificial across diverse sectors.
Some examples of where you will see Aluminium 7075 being used include:
✈️ Aerospace: Components of aircraft structures
🚗 Automotive: Components which are high-performance and low-weight
🛡️ Defense: Military grade firearms like M16, AR-15 rifles
🎯 Sports: Parts of rock climbing bicycles, archery, and bicycles
🏕️ Recreational: Yo-yos made for competition, camping tools, lacrosse shafts
⚙️ Industrial: Components for drag racing engines and mold tooling
