Mu metal vs ferrite sheet.

In this particular case steel is usually the better choice. Our mu metal items on ebay. Ferrite magnet 300g. For example let s say you place a sheet of metal right next to a neodymium magnet.

The first is permeability. 6 3 10 2. At 0 002 t cobalt iron high permeability strip material 2 3 10 2. You should keep that in mind making your selection.

Mu metal is a unoriented nickel iron soft ferromagnetic alloy with very high permeability suitable for sensitive electronic equipment shielding. Mumetal magnetic shielding alloy mu metal grade astm a753 alloy 4 uns n14080 80nife is our most widely known brand. Mumetal chemical composition in weight nickel ni 80 82 molybdenum mo 3 5 6. The difference in properties and performance of ferrites as compared with most other magnetic materials is due to the fact that the ferrites are oxide materials rather than metals.

More recently mu metal is considered to be astm a753 alloy 4 and is. 5 0 10 3. Magnetic capabilities and mechanical properties of mu metal. You want to see a weaker magnetic field on the far side of the metal.

4000 failed verification at 0 002 t ferritic stainless steel annealed 1 26 10 3 2 26 10 3. Ferromagnetism is derived from the unpaired electron spins in only a few metal atoms these being iron cobalt nickel manganese and some rare earth elements. Mumetal doesn t block as much field strength as regular steel. For pefect shielding of magnetic field of neodymium magnet use 10 layers of our 0 35mm thickness mumetal.

The resulting field strength at the. The ratio is expressed as the field strength at a given point vs. The treatment of a metal alloy or other material by heating to a predetermined temperature holding for a certain time and then cooling to room temperature. Iron 99 8 pure 6 3 10 3.

Anything below 0 020 thick is difficult to weld other than with spot welding. Mumetal nickel permalloy sheet for magnetic field shielding 0 2t 30 90cm. A ratio used to measure the effectiveness of a given shield. One such composition is approximately 77 nickel 16 iron 5 copper and 2 chromium or molybdenum.
