Bulk metallic glass (BMG) is a type of metal material that is comprised of amorphous or semi-amorphous metal alloy. This material is distinguished by its highly viscous, glass-like structure and its superior strength and hardness. BMGs have been around since 1960, when German scientist Walter Rohrer first invented them. However, it wasn’t until early 2000s that they began to be used in commercial applications.
BMG alloys offer a number of advantages over traditional metal alloys. The most important of these are their superior strength, hardness, and corrosion resistance. This makes them ideal for a variety of applications including medical implants, cutting tools, consumer electronics, aerospace components, and automotive and industrial components.
BMG alloys are also highly ductile, making them well suited for precision parts, such as those used in electronics and medical industries. They can also be formed into complex shapes with a relatively high degree of accuracy. This makes them a valuable tool for engineers and designers, who can easily tailor material’s properties to suit needs of their projects.
On consumer side, BMGs are often used in consumer electronics, such as cell phones, computers, and tablets. The material’s flexibility and strength allow for devices to be constructed in thin, light, and durable shapes without compromising performance. The material also offers superior corrosion resistance, meaning it won’t degrade over time.
In aerospace industry, BMGs are often used in jet engines, rocket bodies, and high-speed aircraft components. The material’s superior strength and ability to withstand extreme temperatures and pressures make it ideal for these applications. Additionally, BMGs can be used in medical implants and surgical tools, as they can withstand pressure and heat associated with high-speed cutting and drilling.
Finally, BMGs are becoming increasingly popular in the automotive industry, as they can be used to create lighter and stronger auto parts. This helps to improve fuel efficiency and reduce emissions, while still providing superior strength and durability.
Bulk metallic glass alloys offer a number of advantages over traditional metals and alloys, making them an attractive option for a variety of industries. From consumer electronics to aerospace components and automotive parts, BMGs are becoming increasingly commonplace thanks to their superior strength, flexibility, and corrosion resistance.
