NiFe48 Wire

The Crazy Wire Company are best know as suppliers of top quality NiFe48 wire. We have enormous stock levels at all times, as we use this wire to weave our top quality woven mesh products. Our brilliant staff are experts in producing our spools of round wire on our 6 rapid action winding machines. All spools are produced to carry a little extra length to make up for any waste when handling the product.

The NiFe48 wire, with a diameter of 0.3mm (29 AWG) and composed of 48% nickel, is a versatile and reliable material used in various industrial and technological applications. Wires such as this are known for their exceptional corrosion and oxidation resistance, making them ideal for harsh environments. Because of its high nickel content, it is strong and durable, ensuring longevity in applications that are subject to heavy wear and tear. NiFe48 wire also exhibits excellent thermal conductivity and a low coefficient of thermal expansion, which is vital in applications requiring stable performance under fluctuating temperatures.

NiFe48 wire is primarily used in the production of precision resistors. High-precision electronic components can benefit from its resistance stability over a wide temperature range. Various components for the aerospace industry are also constructed using this wire due to its ability to tolerate extreme environmental conditions. It is used for heating elements in electronics due to its consistent heating ability and resistance to high temperatures.

Specification of Wire:

FAQs About This Wire

Is NiFe48 Wire Magnetic?

Yes, NiFe48 wire is magnetic. Nickel is a major component of its composition, which contributes to its magnetic properties. The properties of NiFe48 wire make it particularly suitable for applications that require magnetic responsiveness, such as magnetic sensors, cores, and certain types of electromagnetic devices. With its capacity to respond to magnetic fields, coupled with other qualities like corrosion resistance and thermal stability, the wire is highly versatile in industrial and technological settings.

How Does NiFe48 Wire Resist Oxidation?

NiFe48 wire resists oxidation primarily due to its high nickel content. Nickel is known for its excellent corrosion resistance, particularly against oxidation. This resistance is crucial in environments where the wire is exposed to oxygen and other oxidising agents. The nickel forms a protective oxide layer on the surface of the wire, which acts as a barrier, preventing further oxidation of the underlying metal. This characteristic makes NiFe48 wire highly durable and reliable in harsh conditions, maintaining its integrity and performance over extended periods, even in applications where it is exposed to high temperatures and oxidative environments.
