With 100% business-verified and phone-verified suppliers, buyers can trust direct, legitimate contact and reduce the risk of fraud in a high-stakes technical category. The most common MOQ of just 1 kilogram allows buyers to test materials affordably before scaling up, while the wide reference price range—spanning from $160 to $120,000 per kilogram—means pricing is highly dependent on metal type and purity, so buyers must verify specs upfront to avoid costly misalignment.
