Chemical Composition

Elemental breakdown by percentage weight.

Standard composition limits
Values represent maximum allowed percentage unless otherwise noted.

Physical Properties

Material form, density, and contamination specifications.

Post-use hard drive controller circuit boards; extracted HDD PCBs from decommissioned data storage devices; moderate precious metal content (0.02-0.12g gold; 15-80g copper); ubiquitous data storage e-waste stream (278 suppliers); volume-driven commodity; medium precious metal recovery per unit; RoHS-compliant modern standard; data security protocols important (drive destruction confirmation)

Acceptable Inclusions
  • Gold plating 0.02-0.12g (HDD specification)
  • Copper 15-80g (base metal; valuable)
  • Nickel <3g (plating component)
  • Silver <2g (trace)
  • Solder 5-30g (lead-free modern typical)
  • PCB substrate 20-150g (inert)
  • Semiconductor dies 5-30g (inert)
  • Dust/residue typical (post-drive removal)
Prohibited Materials
  • Gold <0.02g (below HDD specification)
  • Intact drives (must be disassembled; data security)
  • Mercury components (rare; hazmat)
  • Batteries attached (active hazmat)
