Ni50Fe Wire Mesh/Screen
Ni50Fe wire mesh(SMA50) possesses a very high saturation flux density of any
Nickel-Iron alloy. This high saturation flux density combined with high magnetic permeability and low core loss makes them versatile alloys with many potential applications. They are primarily used in laminated cores for instrument transformers, magnetic shield and cores for all certain electronic and communications devices in which extremely high permeability at low magnetizing forces greatly increases the efficiency and effectiveness of the equipment.
To ensure the quality of our product, we can produce the product with raw materials from the international suppliers. Every batch of product can be tracked to the original raw material supplier. We co-operate with international suppliers like Allvac(ATI), Bohler, Carpenter, Dunkirk, Gloria, OttoKumpu, SMC, ThyssenKrupp VDM, Valbruna, etc.
Mesh: 1-250mesh Thickness: 0.05mm and above
Typical Chemistry (Wt.%) of Ni50Fe wire mesh:
Alloy | Ni | Mn | Si | C | Fe |
SMA 50 | 47.5 – 50.0 | 1.0 max. | 0.30 max. | 0.10 max. | Balance |
The chemistry is so adjusted that the alloy shall have highest saturation flux density in the family of all nickel iron alloys.
Magnetic Properties of Ni50Fe wire mesh:
Alloy | Permeability µI | Permeability µmax | Coercive Force Hc (Oe) | Saturation Flux Density Bs (Tesla) |
SMA 50 | 7500 | 100K | 0.05 | 1.6 |
These can be adjusted by different heat treatment practice depending upon the component and its end use.
Physical Properties of Ni50Fe wire mesh:
Alloy | Density (gm/cm³) | Resistivity (µΩ cm) | Curi Temprature (°C) | Thermal Expansion (10-6/°C) |
SMA 50 | 8.2 | 45 | 450 | 8 |
Heat Treatment:
Good results are only obtained by proper heat treatment of finished components. This consists of heating the components in temperature range exceeding 950°C, holding at this temperature and then cooling at determined cooling rate. Controlled atmosphere or very dry gases such as hydrogen or cracked ammonia is necessary to prevent the parts from oxidation.
