Any of the alloys Scott Precision Wire produce can be enamel coated - not just copper.
Applying an enamel coating gives the wire electrical insulation and isolation according to international standards. The high-temperature enamel aids in low to medium temperature applications where adjacent coils of wire may move and touch each other during the heating process with only a small increase in diameter. Scott Precision Wire enamels have a minimum temperature index of 210°C.
Totally flexible solutions with
any order or sample size
From small, one off samples to large, quality controlled orders, Scott Precision Wire offer the best, not only in quality production but with ongoing technical support all backed up with a strong supply chain, huge stock and multiple years of experience.
enamelled wire faq's
Enamelled wire is another name for magnet wire. Enamelled/ magnet wire is generally made from a copper wire, though it can also be made from aluminium, which is coated with a thin layer of insulation; from this latter feature, the given name of ‘enamelled wire’ originates.
Winding wire is another name for enamelled or magnet wire. Winding wire is consequently named because of the form enamelled wire typically takes when installed; enamelled wire is tightly wound around, or coiled, so as to produce an electromagnetic field when charged with an electrical power source.
Magnet wire is used in an assortment of electrical equipment, converting electrical energy into other forms of energy, such as magnetic or mechanical motion. Enamelled wire can be found in transformers transferring energy across circuits; inductors; electrical motors creating mechanical motion; and generators. Magnet wire is used across various industries, from automotive and aerospace, to consumer goods and electronics.
There is little difference between copper wire and magnet wire; typically, magnet wire uses copper as the metallic material for its wire, though aluminium may be preferred on some occasions in larger applications. Copper, however, is more energy efficient and thus is often selected over aluminium for magnet wire. Magnet wire is moreover coated with a thin layer of enamel, or fibrous insulation such as polyester or fibreglass yarn, which differentiates it from copper wire.
Magnet wire is compatible with soldering applications; generally, the wire can be soldered with its enamel coating in place, though some enamel is heat resistant and may require removal prior to soldering. There are plenty of guides regarding how to solder magnet wire which can be consulted before soldering operations.
Magnet wire is insulated with a thin enamel varnish coating, or fibrous insulation, such as polyester yarn or fibreglass yarn. Insulation helps optimise thermal endurance, as well as ensuring the wire can make contact with itself without shorting out; this is necessary for the tight and numerous coils of winding wire.
Enamelled wire is made from copper or occasionally aluminium, both of which are a type of conductive wire. Copper is highly conductive and used in many applications where the conduction of electricity is necessary, such as electrical wiring. It is essential that enamelled wire is fabricated from a conductive material so that it may carry an electric charge and convert this to another form of energy, such as magnetic.
Enamel wire coating must meet various specifications encompassing its electrical, thermal, and abrasion capacity. Insulation coating is often made from polyurethane, polyester, polyester-imide, polyamide-imide, along with several plastics such as fibreglass yarn. Enamel wire coating can be of varying thicknesses, with insulation build, or thickness, relating directly to dielectric strength.
