KA1 Ribbon Spool

The Crazy Wire Company are best known and long established as Europe’s preferred suppliers of top quality KA1 ribbon spool and we also have enormous stock levels at all times as we use this wire to weave our mesh products.

The KA1 ribbon spool, measuring 0.3mm x 0.6mm, is a high-quality FeCrAl A1 wire known for its exceptional performance and versatility in various applications. Designed from FeCrAl alloy, this wire combines iron, chromium, and aluminum to provide superior properties like corrosion resistance. This makes it perfect for environments requiring durability and longevity. With its thin and flat nature, the KA1 ribbon spool’s dimensions facilitate precise and uniform heat distribution, which is particularly useful for applications requiring consistent heating. Because of this, it is an excellent choice for heating systems, laboratory equipment, and electronic components that need to be compact and efficient.

KA1 ribbon spools are highly valued for manufacturing precision resistors due to their stable resistance over a wide temperature range. This ensures reliable performance in electronic circuits. The material’s flexibility and ease of handling make it a preferred material for the manufacture of miniature coils and other intricate electronic components. Due to its thermal properties, the wire is ideal for use in small heaters and specialty lighting. This provides consistent heat output and reducing energy consumption.
