| Appearance | Silver-gray metallic solid, usually supplied as granules, pellets, ingots, or small alloy pieces; metallic luster with smooth surface. |
| Packaging | 100 g, 500 g, 1 kg sealed polyethylene bags with moisture barrier; 5 kg, 25 kg metal containers or customized alloy ingot packaging. |
| Testing Indicators | Appearance — Visual inspection; Alloy composition — ICP-OES or ICP-MS elemental analysis; Metal content — Atomic absorption spectroscopy (AAS); Melting point — Differential scanning calorimetry (DSC) or melting point apparatus; Density — Pycnometer or Archimedes method; Surface oxidation — X-ray photoelectron spectroscopy (XPS) if required; Phase identification — X-ray diffraction (XRD); Impurity analysis — Optical emission spectrometry (OES). |
| Storage Notes | Store in a dry, cool, and well-ventilated area. Keep containers tightly sealed to prevent contamination and oxidation. Avoid contact with strong acids, strong oxidizing agents, and prolonged exposure to moisture. Handle carefully because the alloy may contain toxic heavy metals such as lead and cadmium. Use appropriate personal protective equipment during handling. |
| Lead Time | 10 days |
Arnd's alloy is a low-melting bismuth-containing alloy generally composed of bismuth, cadmium, lead, and tin. It is mainly used as a fusible alloy material in precision casting, temperature-sensitive devices, thermal safety components, metal joining applications, laboratory demonstrations, and specialty engineering applications requiring low melting points.
