Liquidmetal

Liquidmetal® alloys are a family of high-performance metals characterised by an amorphous atomic structure. Unlike conventional metals, whose atoms are arranged in repeating crystalline patterns, Liquidmetal alloys have no long-range ordered structure. This fundamental difference gives the material a distinctive combination of mechanical and physical properties.

The alloys use multi-component chemical compositions that can be adapted to specific applications and manufacturing requirements. By controlling the relationship between composition, processing and atomic structure, properties can be optimised for different uses.

One of the most notable characteristics of Liquidmetal alloys is their high yield strength. Zirconium- and titanium-based alloys in the VIT-001 series, for example, have achieved yield strengths exceeding 250 ksi (approximately 1.7 GPa), more than twice that of some conventional titanium alloys. The amorphous structure also provides high hardness, wear resistance and corrosion resistance, combined with a high strength-to-weight ratio and an unusually high elastic limit.

Another distinctive feature is the way Liquidmetal alloys can be processed. Their behaviour during manufacturing allows complex geometries to be formed using techniques that share characteristics with plastics processing. This provides opportunities for producing precise components while retaining the performance characteristics of a structural metal.

Key properties include:

• High yield strength
• High hardness
• High strength-to-weight ratio
• High elastic limit
• Corrosion resistance
• Wear resistance
• Distinctive acoustic properties
• Potential for forming complex and precise geometries

These characteristics make Liquidmetal alloys relevant for applications requiring a combination of strength, durability, precision and low weight. Applications have included consumer products, sporting equipment and other technically demanding components.

By combining the performance of a structural metal with an unconventional amorphous structure and distinctive processing possibilities, Liquidmetal alloys offer designers and engineers an alternative to conventional crystalline metals for specialised high-performance applications.
