What is CU-ED electrolytic dendritic copper powder used for?
CU-ED is used in diamond tool bond matrix manufacture (saw blades, drill bits, grinding wheels), powder metallurgy pressed-and-sintered structural parts, friction materials and conductive composites. Available in five grades (STD, SFP2, SFP3, SFP8, SFP10). The dendritic particle shape gives excellent compressibility and green strength, ideal for cold-pressed applications where parts must hold shape before sintering.
What purity and apparent density range does CU-ED cover?
CU-ED has copper purity of Cu 99.0% min across all grades. Apparent density ranges from 0.65 g/cc (SFP10) to 2.7 g/cc (STD), reflecting the dendritic (tree-like) particle morphology of electrolytic deposition. Lower-density grades offer higher surface area and reactivity; higher-density grades offer easier handling. This is a direct consequence of the irregular particle shape that provides interlocking and green strength.
How do dendritic and spherical copper powders differ?
Dendritic copper (CU-ED) is produced by electrolytic deposition with irregular tree-like particle shape, high surface area, excellent compressibility and green strength in pressed parts. Spherical copper (CU-AT) is gas-atomised with free-flowing spherical particles, better suited for thermal spray, cold spray and additive manufacturing. Dendritic apparent densities: 0.65–2.7 g/cc. Spherical: 4.0–4.8 g/cc.
Can I order small or sample quantities of CU-ED?
Ronald Britton supplies CU-ED in sample quantities for laboratory testing and development, up to multi-tonne production quantities. All five grades (STD, SFP2, SFP3, SFP8, SFP10) ship from UK stock with typical dispatch within 48 hours, with full ISO-certified documentation and batch traceability.
Can I get a Technical Data Sheet for CU-ED?
Yes. Technical Data Sheets covering all five grades (STD, SFP2, SFP3, SFP8, SFP10) with chemical composition, particle size distribution, apparent density, flow rate and physical properties are available on request. Safety Data Sheet (SDS) also available.
Do you supply CU-ED internationally?
Yes. Ronald Britton supplies CU-ED electrolytic dendritic copper powder to manufacturers in 20+ countries. All five grades available. We handle export documentation, hazardous goods shipping and advise on compliance. All shipments include ISO-certified quality documentation and batch-level Certificates of Analysis.
