7068 alloy is a 7000 series aluminium-zinc alloy registered with the US Aluminium Association and produced to AMS 4331 (chemical composition and mechanical properties) and AMS 2772 (heat treatment). 7068 alloy ‘A’ and ‘B’ tensile data and fatigue properties have been ratified for inclusion in MIL Handbook 5 / MMPDS.
Aluminium-silicon alloys typically contain 3% to 25% silicon content. [1] Casting is the primary use of aluminum-silicon alloys, but they can also be utilized in rapid solidification processes and powder metallurgy. Alloys used by powder metallurgy, rather than casting, may contain even more silicon, up to 50%. [1]
The T6 temper is usually achieved by homogenizing the cast 7075 at 450 °C for several hours, quenching, and then ageing at 120 °C for 24 hours. This yields the peak strength of the 7075 alloys. The strength is derived mainly from finely dispersed eta and eta' precipitates both within grains and along grain boundaries.
During the casting process, the molten aluminum is injected into the mold and burns off the resin, leaving an area of localized hypereutectic aluminum only in the area of the cylinder bore. The silicon particles are then mechanically exposed in a similar process to an Alusil block resulting in a cylinder block that functions in the same way as ...
Cast aluminium alloys yield cost-effective products due to the low melting point, although they generally have lower tensile strengths than wrought alloys. The most important cast aluminium alloy system is Al–Si, where the high levels of silicon (4–13%) contribute to give good casting characteristics. Aluminium alloys are widely used in ...

6061 aluminium alloy (Unified Numbering System (UNS) designation A96061) is a precipitation-hardened aluminium alloy, containing magnesium and silicon as its major alloying elements. Originally called "Alloy 61S", it was developed in 1935. [ 2 ]
Aluminium magnesium boride or BAM is a chemical compound of aluminium, magnesium and boron. Whereas its nominal formula is AlMgB 14 , the chemical composition is closer to Al 0.75 Mg 0.75 B 14 . It is a ceramic alloy that is highly resistive to wear and has a low coefficient of sliding friction.
