Another format of MuMetal, great for MagField Shield Protyping and for Joining MagField Shielding sheets.
$75.00 + gst / 30cm (enough for 12 nail heads @ $6.25 / nail head).
$211.00 + gst / metre (enough for 40 nail heads @ $5.28 / nail head).
Specify desired lengths up to 30mt.
When you need more than one MagField Shielding sheet to cover an area, how do you handle the joints?
Joint-Shield is the perfect solution!
This is a generous 0.25 millimetres thick, fully hydrogen annealed magnetic shielding alloy with adhesive backing
(rated -15 to 35
oC) on one side.
Simply overlap MagField Shielding sheets by 50mm, use clouts to secure the top and bottom of the sheets and cover
the nail heads with a 5 X 5cm square of Joint-Shield.
For an even more secure system "tape" over the seams with Joint-Shield high permeabilty alloy.
Simple to use: just cut to desired length with a heavy scissors, peel the protective backing and press into place!
Joint-Shield can also be used by itself as an excellent magnetic shielding material when a 10cm width and adhesive backing
is desirable (wrap it around wiring and conduit, speaker magnets, even small appliances like shavers and hair dryers!).
Joint-Shield can be shaped by hand, without the need for special tools, but watch the sharp edges.
IMPORTANT NOTICE:
While special alloys in Magnetic Shielding Foils exhibit high magnetic permeability and the electrical conductivity of the E and
RF Shielding Fabrics makes them more attractive to Electrical Fields than humans, there are many factors that affect
the amount of shielding you will achieve by using these materials.
The list of such factors includes: size and shape of the field source, size and shape of the shielded area,
seams in the shielding material, frequency of the field, distance from shield to source, orientation of shield to the source, thickness and treatment of shielding material, etc.
Because there is little to no control over many of these factors, we cannot and do not guarantee any specific shielding
performance for a specific application of these materials.
Also, note that foils, ribbons and plates, once cut to your specifications, are not refundable.
If you are not sure how to use these materials, you may call for suggestions or I may even be able to locate the name of
an experienced shielding designer/installer in your area who can assist in designing your shield.
