FeCrAl A1 Resistance Wire

The Crazy Wire Company are best known and long established as Europe’s preferred suppliers of top quality FeCrAl A1 resistance wire. We have enormous stock levels at all times as we use this wire to weave our mesh products.

FeCrAl A1 Resistance Wire, measuring 0.48mm (25 AWG), is a versatile and durable material, widely recognised for its exceptional performance in various industrial and commercial applications. The alloy of iron, chromium, and aluminum used in this wire is known for its high electrical resistance and stability at high temperatures. The material’s robust composition makes it suitable for heating elements in small appliances like toasters and hair dryers since it can withstand prolonged heat exposure without degrading. It is commonly used in furnace elements and kilns, where it plays a crucial role in maintaining consistent heat distribution. Because the FeCrAl A1 Resistance Wire is oxidation-resistant, it is reliable and lasts longer, reducing the need for frequent replacement.

Apart from its thermal properties, the wire is also corrosion-resistant, making it suitable for use in environments where corrosive substances are present. Chemical processing industries can use this wire because of its chemical resistance. Designed and manufactured to cater to specific requirements, the material’s mechanical strength and ease of fabrication make it easy to shape and install. Having a high resistance to sulfur environments also makes this wire popular in applications involving sulfur compounds.

FAQs About This Wire

Is FeCrAl A1 Resistance Wire Safe For Food-Grade Applications?

Food-grade applications can generally be performed with FeCrAl A1 Resistance Wire. An alloy of iron, chromium, and aluminum is used to make this wire, which is commonly found in food-grade equipment. When considering materials for food-related applications, corrosion and oxidation resistance are essential qualities.

Even though the wire itself is safe, the overall safety of a food-grade application depends on various factors, including the design, installation, and usage of the equipment or heating element incorporating the wire. To ensure compliance with safety standards and avoid potential contamination, it’s imperative to follow industry-specific guidelines and regulations when using materials, such as FeCrAl A1, in food-grade applications.

Additionally, it is recommended to consult with experts and professionals in the area of food-grade equipment and materials to ensure that your specific application meets all safety standards and requirements.
