MuMetal JOINT SHIELD & MAGNET SHIELD

Description

Great for Magnetic Shield Prototyping and for Joining Mag-StopTM Plates When you need more than one Mag-Stop Plate to cover an area, how do you handle the joints? Joint-Shield is the perfect solution! This is a generous .010″ thick, fully hydrogen annealed magnetic shielding alloy with adhesive backing (rated 0 – 200°F) on one side. Simply butt the Mag-Stop plates tightly together, and “tape” over the seam with Joint-Shield high permeability alloy. This method offers much less bulk and better appearance than the old overlap technique and provides excellent shielding integrity. Simple to use: just cut to desired length with a heavy scissors, peel the protective backing and press into place! when a 4″ 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.

MuMetal Join Shield is .010″ thick, fully hydrogen annealed magnetic shielding alloy with adhesive backing (rated 0 – 200°F)!
Butt joints tightly two plates and cover over the joints with Joint Shield (see diagram at left)
Joint-Shield can also be used by itself as an excellent magnetic shielding material either flat or molded by hand into shapes.
