Licensed Neodymium material.
8mm dia x 5mm thick.
0.31 in. dia x 0.2 in. thick.
Each magnet's north and south pole are on opposite 0.31 in. diameter faces.
Each magnet can support a steel weight of up to 3.96lbs vertically from the magnetic face when in flush contact with a mild steel surface.
Excellent resistance to demagnetization.
Coated with three layers of nickel, copper and nickel to reduce corrosion and provide a smooth finish.

These Neodymium disc magnets may be small but they have an astonishing pull of 3.96lbs. Every magnet has a triple coating of nickel, copper and nickel again to prevent against corrosion. Our Neodymium magnets are commonly used in creative applications such as modelling and theatre design, furniture making, exhibition stands and packaging. They also have many uses in engineering and manufacturing where small size and maximum strength are required. What's more, because of their resistance to demagnetization they are ideal for creating a shock-absorbing or damping effect when used to repel other magnets.
