Phosphorus copper block
Phosphorus copper blocks for high-end PCB and general electroplating.
Hazard Characteristics
Not hazardous in solid form. Machining or melting may produce dust or fumes.
Applications
Phosphor copper in irregular block form covers the same bright acid copper chemistry as phosphor balls while fitting basket, rack, or bulk-loading needs where footprint and weight distribution vary; dissolution stays even and dross remains predictable when phosphorus is held in spec.
PCB & Electronic Substrates
PCB & Electronic Substrates
Chunk anodes for board shops with basket lines—irregular fill still presents stable surface area trends once inventory practice is standardized.
Decorative & Hardware
Decorative & Hardware
Hardware bright copper when operators prefer bulk break-up feeding; blocks settle predictably compared with mixed scrap inputs.
Automotive Electronics
Automotive Electronics
Automotive plating cells that blend manual dosing with basket anodes can stage blocks for gradual replenishment.
Industrial Interconnects
Industrial Interconnects
Industrial interconnect plating—terminals, brackets, and bright lines that mirror the demands of decorative acid copper but tolerate heavier anode packs.
Key Features
High Purity
Made from high-purity electrolytic copper with extremely low impurities, ensuring a clean plating bath.
Uniform Phosphorus Distribution
Even phosphorus distribution ensures smooth anode dissolution and minimizes anode slime generation.
Precise Phosphorus Control
Phosphorus is customizable on demand: typically 0.025%–0.055%, extendable to 0.1%–0.3%, monitored end-to-end with regular high-precision chemical analysis.
Excellent Stability
Dense crystallization provides outstanding plating stability in sulfate bright copper plating systems.
