John Kang Liquidmetal | Facts You Should Know
John Kang is a Liquidmetal advocate. First revealed to the public in the mid-2000s by researchers at the California Institute of Technology, Liquidmetal is a material that has the potential to make an impact in many different fields ranging from sports to medicine.

- Liquidmetal has been around for more than a decade. This seemingly new material isn’t exactly new, says John Kang. Liquidmetal was first introduced in 2003 after years of development by Caltech researchers, and was first used commercially in golf clubs manufactured by Liquidmetal Technologies. Since then, scientists have found hundreds of uses for this versatile material.
- Despite its name, Liquidmetal is not liquid. In fact, John Kang believes Liquidmetal is one of the hardest and toughest materials around. The “liquid” in the metal’s name comes from the fact that it behaves somewhat like glass, which doesn’t have a true melting point and instead increases its viscosity as the temperature increases. This property is typical of so-called amorphous metals, which are non-crystalline unlike common metals and alloys. Image Source: Phys.org
- Liquidmetal has several unique and interesting properties. Among this alloy’s other properties include low softening temperatures compared to the melting points of other metals, which allows metalworkers to cast them into complex shapes without losing strength. John Kang Liquidmetal can actually replace thermoplastics for certain applications. Furthermore, Liquidmetal is harder than other alloys that contain aluminum or titanium. Crystalline metals tend to become deformed when force is applied to them; in contrast, Liquidmetal tends to “spring back”, holding its shape and structure well.
- You’ve probably used Liquidmetal at some point. In 2010, Apple and Liquidmetal Technologies came up with a deal that allowed Apple to use Liquidmetal in their products. If you have an Apple iPhone 3G or a similar model, the SIM ejector pin is actually made of that material, say John Kang. Liquidmetal is the ideal material for something so small yet so important, as it is so tough that you’re likely to hurt yourself first before to manage to bend it successfully. Other consumer products, such as certain SanDisk “Titanium” USB drives, are also made from Liquidmetal.
- Scientists are constantly finding new uses for Liquidmetal. While Liquidmetal was first used in golf clubs, John Kang Liquidmetal in other pieces of sports equipment, such as golf balls, baseball bats, and tennis racquets. The metal’s toughness has led researchers to explore possible applications in space and defense, and it might have been used in oil drilling rigs. But the most exciting applications for Liquidmetal lie in the field of medicine. Surgeons are already using Liquidmetal scalpels, and biomedical engineers have successfully experimented with Liquidmetal replacement joints. Moreover, researchers are looking into replacing titanium-based pacemaker components with those made of Liquidmetal, which can be manufactured with greater precision at a lower cost.
John Kang Liquidmetal will see greater use in the future. Consumers and manufacturers alike are demanding increasingly precise and durable parts, and Liquidmetal is in a unique position to fill that demand.
