Do hard drive platters contain precious metals?
The logic boards off a scrap hard drive are considered a premium grade of circuit board scrap. They are worth more than computer motherboards because they are more densely packed with trace amounts of precious metals (parts per million).
What kind of metal are hard drives made of?
Hard disks are rigid platters, composed of a substrate and a magnetic medium. The substrate – the platter’s base material – must be non-magnetic and capable of being machined to a smooth finish. It is made either of aluminum alloy or a mixture of glass and ceramic.
