FAQs
Q: Are your core rods RoHS-compliant?
A: Yes – all grades meet RoHS, REACH, and UL safety standards.
Q: Can I request custom permeability values?
A: Absolutely – we tailor silicon content and annealing processes to meet specific B-H curves.
Q: What tolerances do you guarantee?
A: Dimensional tolerance: ±0.1 mm; permeability variance: ±3%.
Package
Pure iron is typically packaged with rust-preventive oil, wrapped in plastic film, and secured with plastic or metal straps. It is then placed on wooden pallets or in wooden crates, sometimes using moisture-proof paper or vacuum packaging for extra protection during transportation and storage.
