NiFe48 Nickel Wire

The Crazy Wire Company are best know as suppliers of top quality NiFe48 nickel 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.

NiFe48 nickel wire, measuring 0.2mm in diameter and commonly known as 32 AWG, is a specialised wire material predominantly composed of nickel (48%) and iron. In various industries, this wire is highly sought after due to its unique combination of properties. As a result of its high nickel content, it has remarkable resistance to corrosion. This makes it an ideal choice for environments where durability and longevity are important. The corrosion resistance of these materials is particularly beneficial for marine applications. This is where saltwater and other corrosive elements are regularly encountered.

NiFe48 nickel wire has a comparable thermal expansion coefficient to borosilicate glass, which is another key characteristic. This makes it ideally suited to glass sealing applications, since it expands and contracts at a rate that closely matches the glass, thereby eliminating cracking and damage over time. Among electronics professionals, this wire is particularly valued for its consistent and predictable resistance properties. A reliable choice for precision resistors and other electronics components where stable performance is critical. It maintains a stable resistance over a wide range of temperatures.

Specification of Wire:

  • Diameter – 0.2mm (200 Micron – 32AWG)

FAQs About This Wire

Are There Any Limitations In Using 0.2mm NiFe48 Nickel Wire?

There are some limits associated with using 0.2mm NiFe48 Nickel Wire, as with any specialised material. The wire’s small diameter of 0.2mm, while advantageous for certain applications, may not be suitable for heavy-duty or high-load situations that require thicker, stronger wires. Furthermore, NiFe48 wire may not perform as well in extremely acidic or alkaline environments as some other specialised materials. However, it is corrosion resistant.

Even though the wire’s resistance properties are stable, the wire will not meet the resistance requirements for applications requiring very low or very high resistance. It is also possible that NiFe48’s specific magnetic properties are not ideal for all applications due to its particular magnetic properties.

The cost of NiFe48 wire might be higher than standard nickel wires, which could be a limiting factor for budget-conscious projects. The thermal expansion properties of NiFe48 wire may limit its use to those with the necessary technical expertise, especially those who know how to handle it.

How Resistant Is NiFe48 Wire To Mechanical Stress?

NiFe48 wire, while known for its corrosion resistance and stable electrical properties, has moderate mechanical stress resistance. Its resilience to mechanical stress, like bending or twisting, is generally good due to the inherent ductility and strength provided by its nickel-iron composition. However, the 0.2mm thickness (32 AWG) of the wire, while offering flexibility, may also limit its ability to withstand very high mechanical stresses or heavy loads.

In applications where the wire is subjected to constant movement or bending, NiFe48 wire can maintain its integrity to a reasonable extent. However, it may not be the best choice for extremely high-stress applications where more robust wires or materials are required. The wire’s performance under mechanical stress also depends on the specific conditions of use, such as temperature and environmental factors, which can affect its durability and strength over time.
