Metglas is a thin, amorphous metal alloy ribbon produced by using a rapid solidification process. Its ferromagnetic properties allow the ribbon to be magnetized and demagnetized quickly and effectively with very low core losses. Metglas chemical etching is ideal for various applications including electronic surveillance components, aerospace materials, and more.
Fotofab's chemical etching process produces designs that can withstand harsh indoor and outdoor environments. The process uses a strong caustic chemical to etch the unprotected parts of a metal surface to create a design or image formed to your project's specifications.
Fotofab products are made in the USA and distributed worldwide.
Characteristics of Metglas
Metglas cools to an amorphous (glassy) structure that makes it stronger, lighter, and springier than other materials. Other characteristics include:
- Low core losses of approximately 5 mW/kg at 60 Hz
- A non-crystalline structure
- High permeability, strength, and hardness with flexibility and toughness
- Magnetically soft
- Low coercivity
- Superconductivity
- High tensile yield strengths
- High elastic strain limits
- High resistance
Acid Etching for Metglas Applications
The superconductivity of Metglas at lower temperatures makes it ideal for a variety of applications, including:
- High-efficiency transformers
- Electronic surveillance
- Aerospace materials
- Semiconductors
- Pressure sensors
Other Factors
- Also known as metallic glass alloys or glassy metal
- Amorphous metals can be grouped into two categories: non-ferromagnetic and ferromagnetic
- Has a glass-like structure
- The structure is not crystalline, but rather disordered
- The development of amorphous metals began in 1970
- There are several ways amorphous metals are produced including extremely rapid cooling, physical vapor deposition, solid-state reaction, ion irradiation, and mechanical alloying
