Stainless Steel Microspheres

Product Introduction:

Stainless steel microspheres are typically produced from high-quality 304-grade stainless steel, known for their excellent corrosion resistance and mechanical strength. These microspheres have a wide range of sizes and can be customized for different applications. The spheres are engineered to have a highly spherical shape, which ensures consistent performance, uniform behavior, and precise application. Their spherical geometry contributes to smooth flow characteristics and minimal friction, making them ideal for use in applications requiring consistent, predictable behavior.

The highly spherical 304 stainless steel metal microspheres supplied by Alfa Chemistry have a wide range of sizes, ranging from 1 μm to 1.2 mm, and are in the form of free-flowing dry powder. These microspheres are specifically designed to be non-magnetic and are therefore not suitable for magnetic applications. They are commonly used as conductive spacers in bond line applications, where precise and consistent spacing is critical for performance. Another major use of stainless steel microspheres is as high-density test projectiles. They are used in testing scenarios where accurate and uniform projectiles are required to simulate conditions such as impact, velocity, and penetration.
