Nano crystalline soft magnetic material is a new development. The material composition is 82% iron with the remaining balance silicon, boron, niobium, copper, carbon, molybdenum, and nickel. The raw material is manufactured and supplied in an amorphous state. It is recrystallized into a precise mix of amorphous and Nano crystalline phases when annealed, giving the material it's unique magnetic properties.
Comparing with the traditional core material, such as silicon steel and perm alloy, Iron based nano crystalline alloy takes the advantage of high permeability and low cost, and is thus more competitive in the application of precise current transformer with 0.2, 0.2s, and 0.1 accuracy class.This material has the best overall performance over a broad range of frequencies when compared to other available materials. It's relatively high saturation flux density, combined with its incredible low loss and high permeability through a wide frequency range, makes it useful in many applications
Process DescriptionPML have the facility to make cores of various sizes in nano crystalline and amorphous material with ribbon thickness 25-35 microns. The cores are made on automatic core winding machine to give very high production rate. The cores are finally heat treated in controlled atmosphere in our high tech furnace to achieve optimum material performance. Later cores are then plastic encapsulated or epoxy coated as per the customer requirement and tested 100% for quality performance on core sorting machines and dispatched.
The Nano crystalline Cores For Leakage Circuit Breakers may be provided in the form of toroidal or sports-shaped entangles core. The material for Nano crystalline Cores For Leakage Circuit Breakers is brittle and needs protection to prevent mechanical forces, It is provided by a plastic core or a suitable heat-resistant coating. Once Coated or boxed, the core is very strong, the main magnetic properties Highly linear and less dependent on temperature. In one aspect, the strip material limits the diversity of the shape of the mechanical core, but is limited The geometry of other hand-variable ring cores can be obtained at low processing costs. Of The current core size ranges from about 10 mm to more than 300 mm from the outside diameter diameter. Basically, spaces or cut cores should also be available, however These options are not currently available as a standard on the market.

PMLoffers several other alloys which are used for similar, but different applications. MuMETAL Stress Annealed sheet is used primarily in low intensity fields where high attenuation is desired (high initial permeability & high shielding efficiency). Available as stress annealed (partially annealed for ease of machinability).
MuMETAL is used for fabricated shields such as enclosures, cylinders, cans, channels or 3D boxes. Typically, atmospherically controlled Perfection Annealing is required after stamping, machining, bending, rolling or welding to provide maximum shielding performance. MuMETAL alloy is available in many forms, but most shields are fabricated from our sheet or coil stock in gauges from 0.014" to 0.062" thickness [0.36mm to 1.57mm] .
Co-NETIC AA wire is widely used in fabrication of magnetic shielding braid to certain customer specifications where our stock Co-NETIC AA Cable Shield may not be specified. Four stock diameters are available.

Each probe is carefully calibrated with the calibration number shown on the probe. Probe is accurate for direct measurements from 10Hz to 3000Hz in Transverse directions. Includes BNC Connector.
Transverse directional - 60 millivolts peak per Gauss at 60 Hertz.
MuMETAL Foil is used primarily in low intensity fields where the highest attenuation, highest initial permeability (Mu) and highest shielding efficiency are desired. MuMETAL Foil is fully annealed and available in stock gauges from 0.002" to 0.010" thickness [0.05 mm to 0.25 mm] .
Foils can be slit to a minimum width of 1/4" (6.35 mm). Foil width tolerance is 0.010" (0.25 mm).
Unlike MuMETAL Stress Annealed Sheet, our Foils do not require re-annealing unless severe forming or heliarc welding is performed.

Iron is probably one of the most abundantly available materials in nature and is also being used to a large extend in various products. The use of iron is extensive in all walks of life due to its inherent superior mechanical properties and its availability as compared to other materials. Most of the products are manufactured / produced on machines / equipments which are built using iron. This leads to iron contamination of the products.
The iron contamination may be in the loose form or compound form or it could be in the alloy form depending on the process. Though this is part and parcel of the process, the iron contamination is undesirable in most of the products and contamination levels are governed by guidelines set by BIS and other international standards. This is more so in food processing industry.

A current transformer (CT) is used for measurement of alternating electric current. Current transformers, together with voltage (or potential) transformers (VT or PT), are known as instrument transformers. When current in a circuit is too high to apply directly to measuring instruments, a current transformer produces a reduced current accurately proportional to the current in the circuit, which can be conveniently connected to measuring and recording instruments.
A current transformer isolates the measuring instruments from what may be very high voltage in the monitored circuit. Current transformers are commonly used in metering and protective relays in the electrical power industry.
Precast Concrete Magnet/ Shuttering Magnet is the new type building material widely used in construction site, High- Developments projects, etc, Railway Infrastructure projects etc. in precast concrete form-work system. There by increasing building stability, while reducing labor costs and cost savings.
The precast concrete Form-works are afforded the opportunity to properly cure and be closely monitored by plant employees. Using a precast concrete form-work offers many potential advantages over on-site casting. Precast concrete production performed on ground level, which helps with safety throughout a project.
