· TiBe

TiBe is an intermetallic compound combining titanium and beryllium, representing a lightweight metallic system with high stiffness and low density. This material belongs to the family of refractory intermetallics and remains largely experimental; it has been investigated primarily in aerospace research contexts where extreme strength-to-weight ratios and elevated-temperature performance are critical. TiBe is not widely commercialized due to beryllium's toxicity concerns, processing difficulty, and cost, but it represents a material of interest for specialized applications where traditional titanium alloys or aluminum-beryllium composites fall short.
