While metallic glass has existed for decades, the majority of people became aware of its revolutionary properties when it was introduced as a product by Liquidmetal Technologies. Many people have seen our popular ”bouncing ball” demonstration on Youtube, where ball bearings dropped on plates of steel and titanium stop bouncing after a few seconds, while the ball on a plate of Liquidmetal seems to bounce well over a minute.
Magnetic resonance imaging (MRI) is widely used for imaging soft tissue in clinical and pre-clinical medicine for many reasons. Not only does MRI provide excellent contrast between various tissue types, but it does not require the use of ionizing radiation such as x-rays (CT Scanners) or gamma-rays (PET scanners). The theory of MRI is based on the interaction of subatomic particles with magnetic fields in a process called nuclear magnetic resonance (NMR), which describes how atomic nuclei with a quantum property called ‘spin’ precess in a magnetic field the same way that a gyroscope or a spinning-top precesses in the earth’s gravitational field (if you’re not familiar with gyroscope precession, watch this video).
For this reason, the primary component of an MRI scanner is a very powerful magnet, which generates a very strong magnetic field (typically 1.5-3 Tesla, or about 3,000 times the strength of the Earth’s magnetic field) where the object is being imaged, and also in the region surrounding the magnet.
For designers who have traditionally expected dull, unattractive and pitted surfaces of traditional metal injection molded and die-cast parts, seeing the gorgeous as-cast surface of a Liquidmetal part comes as a shock. Liquidmetal parts have a shiny metallic luster straight from the mold without the need for time-consuming and costly secondary operations.
Liquidmetal alloy’s beautiful finish begins with using high purity alloy feedstock provided by one of the world’s leading metallurgical companies, Materion Brush. Liquidmetal Technologies then feeds that alloy into its own proprietary high purity vacuum injection molding platform.
