Al77B923

Al77B923 is an aluminum-based metal alloy containing boron as a significant alloying element, belonging to the aluminum-boron family of advanced lightweight materials. This alloy is used primarily in aerospace and high-performance applications where weight reduction and strength retention are critical; the boron addition typically enhances hardness and wear resistance compared to conventional aluminum alloys. The material is notable for its potential in applications requiring reduced density with improved mechanical properties, though it remains less common than standard Al-Cu or Al-Mg systems in mainstream engineering.
