Alumina Interlocking Beads
Alumina beads, also known as alumina interlocking fish spine beads, are versatile and perfect for applications requiring high temperature and electrical insulation. These beads come in a variety of bore sizes and densities to accommodate different needs. Alumina beads, which are resistant to abrasion, are the go-to choice when you need to shield wires from heat while maintaining the ability to manipulate the wire’s position. Their interlocking fish spine design enables easy connection and shaping, enhancing their versatility. Interlocking alumina beads find use in numerous applications, especially those necessitating continuous electrical insulation. They are commonly used in air or vacuum systems, shielded coaxial vacuum cabling, 3D printers, and projects that require complex layout patterns, among others.
