The mineral may be drawn into a wire. Obviously not easy to test. Malleable materials also may be ductile.
May be cut smoothly with a knife. Relatively few minerals are sectile.
If bent, will spring back to its original position when the stress is released.
If bent, will not spring back to its original position when the stress is released. It stays bent. In contrast, flexibility is the ability of a material to deform elastically and return to its original shape when the applied stress is removed.
