FAQs About This Wire

What Is The KA1 Half Staggered Fused Clapton Wire Made Of?

The KA1 Half Staggered Fused Clapton wire is made of FeCrAl A1, an alloy that is a combination of iron (Fe), chromium (Cr), and aluminum (Al).

FeCrAl A1 is renowned for its superior heat resistance and electrical conductivity. The chromium in the alloy offers excellent resistance to oxidation, even at elevated temperatures. This means that when the wire is heated, it forms an adherent layer of chromium oxide, protecting the inner material from further oxidation and ensuring consistent performance over time. The aluminum content enhances the heat resistance and contributes to the alloy’s high-temperature strength.

In addition to these attributes, the alloy’s inherent stability makes it a preferred choice for applications where consistent, high-temperature performance is crucial. Its durability and resistance to deformation under heat, combined with its electrical properties, make FeCrAl A1 an ideal choice for intricate projects requiring precision and stability, such as the KA1 Half Staggered Fused Clapton wire.

How Long Is A Spool Of KA1 Half Staggered Fused Clapton Wire?

A spool of KA1 Half Staggered Fused Clapton wire is 5 metres in length, which is approximately 15 feet.
