Relevant Standards.
ASTM B170
Standard Specification for Oxygen-Free Electrolytic Copper. Defines purity grades and test methods for high-purity copper.
ASTM B348
Standard Specification for Titanium and Titanium Alloy Bars and Billets. Grades 1–38, mechanical and chemical requirements.
DIN 17742 / ASTM B161
Specification for nickel and nickel alloys. Wire forms, tolerances and test methods.
ISO 9001:2015
Quality management system. Requirements for processes, documentation and continuous improvement.
REACH
EU Regulation No. 1907/2006. Registration, evaluation, and authorization of chemical substances.
RoHS
Directive 2011/65/EU. Restriction of hazardous substances in electrical and electronic equipment.
Terms & Definitions.
99.9999% purity — maximum 1 ppm (parts per million) metallic impurities. The highest commercially available purity grade for copper.
Inductively Coupled Plasma – Optical Emission Spectrometry. Standard method for quantitative determination of metallic trace elements in high-purity metals.
Certificate of Analysis — certificate with actual measured values of a specific batch. Included with every Hansemut delivery.
Material Safety Data Sheet / Safety Data Sheet — safety data sheet per EU Regulation (EC) No. 1907/2006. Contains hazardous substance, transport and storage information.
Median of the particle size distribution. 50% of particles are smaller, 50% are larger than the D50 value. Measured by laser diffraction.
Analytical method for determining the elemental composition and purity of metals. Spark Source Mass Spectrometry (SSMS) enables detection of trace impurities at sub-ppm levels — standard for 6N purity verification.
Designation for very fine metal powders with grain sizes typically in the single-digit micrometer range (e.g. 4–10 μm). Ultradisperse powders enable homogeneous distribution in pastes, compounds and sintering applications.
Documentation issued by the manufacturing partner confirming material specifications, purity analysis and batch traceability. Accompanies every Hansemut delivery as part of the complete documentation package.
Source material for PVD (Physical Vapor Deposition) coating. High-purity metal is sputtered in a vacuum and deposited as a thin film on a substrate.
Free Carrier (Incoterm) — delivery condition where the seller hands over the goods to the carrier at the named place. From this point, the buyer bears the transport costs.
