The 0.38mm (27 AWG) KA1 FeCrAl A1 Electrical Wire is a highly versatile and reliable product designed to meet various electrical and engineering needs. With its exceptional high-temperature stability and resistance to oxidation, FeCrAl (Iron-Chromium-Aluminum) wire is ideal for harsh environments. Its diameter of 0.38mm makes it ideal for detailed work, and the 27 American Wire Gauge (AWG) wire offers excellent precision. Its composition ensures durability and reliability, which is equally important for applications that are dependent on durability and dependability.

Electrical wires made of FeCrAl A1 have a high resistance to corrosion and are suitable for use in furnaces, kilns, and heating elements. Electronic appliances and laboratory equipment that require precise temperature control benefit from its thermal efficiency and strength. As a result of its flexibility and strength, aluminum wire is a great choice for crafting intricate wire meshes and filters, especially for chemical and aerospace industries.

FAQs About This Wire

Can FeCrAl A1 Electrical Wire Be Used In Laboratory Equipment?

Yes, FeCrAl A1 Electrical Wire can be effectively used in laboratory equipment. Its high resistance to oxidation and stability at elevated temperatures make it particularly suitable for applications where precise temperature control and durability are essential. This wire’s properties ensure consistent performance in various laboratory settings, including heating applications, experimental setups, and specialised instrumentation. Its reliability under different environmental conditions also contributes to its suitability for use in a wide range of laboratory equipment.

How Does FeCrAl A1 Wire Behave Under Mechanical Stress?

The FeCrAl A1 wire exhibits good mechanical stress behavior due to its robustness and durability. Due to its composition, which includes iron, chromium, and aluminum, it is highly resilient and able to withstand mechanical stress such as bending, twisting, and stretching. It is important to note that, like all metals, when it is subjected to extreme or repetitive mechanical stresses outside its specified tolerances, it can become fatigued or deformed, even if it maintains structural integrity under normal handling and installation procedures. As a result, if there will be a significant amount of mechanical stress, it’s advisable to consult the wire’s specifications and ensure its suitability to the application.
