20 AWG Ni80 Flat Clapton

The 20 AWG Ni80 Flat Clapton wire, sold in 5-metre spools, is a high-quality resistance wire composed of a 20 AWG (American Wire Gauge) core and a tightly wound 32 AWG outer wire. Both the core and the wrapping wire are made of nickel-chrome alloy Ni80, which is an 80/20 blend of nickel and chromium. In addition to being highly resistant to heat, this wire provides an even heat distribution over a variety of applications due to its 2.20 ohms per meter resistance.

Known for its excellent thermal properties and durability, this Ni80 Flat Clapton wire is frequently used in aerospace applications. Having a flat clapton configuration increases the wire’s surface area, enhancing its ability to provide even and consistent heating. Due to its versatility and ease of use, it can be used to craft custom coils for a wide variety of electronic systems and heating elements.

Wire comes on a spool to ensure it remains tangle-free and is easy to cut to the desired length, making user experience convenient and efficient. Its 5-metre (approximately 15 feet) length makes it perfect for both recreational and professional uses.

FAQs About This Wire

What Are The Thermal Properties Of 20 AWG Ni80 Flat Clapton?

The 20 AWG Ni80 Flat Clapton wire exhibits excellent thermal properties due to its composition of 80% nickel and 20% chromium. This alloy is known for its high resistivity and ability to withstand elevated temperatures without significant degradation. The wire heats up quickly and cools down at a steady rate, providing consistent performance across a range of applications. Additionally, the flat clapton configuration increases the surface area of the wire, which further enhances its heat distribution capabilities. As a result, the 20 AWG Ni80 Flat Clapton wire is suitable for applications requiring stable and reliable heating elements.

Can 20 AWG Ni80 Flat Clapton Be Used In Marine Environments?

20 AWG Ni80 Flat Clapton wire, made from an alloy of 80% nickel and 20% chromium, is resistant to corrosion and oxidation, so it can be used in marine settings. While it may be durable, it may not be as corrosion-resistant as some other materials designed specifically for marine applications, such as certain stainless steel alloys. In order to determine if 20 AWG Ni80 Flat Clapton wire is appropriate for your marine application, it’s important to assess your application’s specific conditions and requirements. Ni80 alloy can withstand moisture and salinity better than most alloys, but it’s still necessary to assess these factors before making a construction decision.
