Carbon Electrode 6mm

Graphite Electrode Ø 6 mm (BMG‑010) Short Description The Graphite Electrode Ø 6 mm (BMG‑010) is a durable, chemically inert electrode rod made from high‑density fine‑grain graphite. Designed for use as an anode or electrode in electroplating processes, it is ideal for bath, pen, and pad plating applications where a clean, metal‑free current supply is essential.  Product Description This graphite electrode is manufactured from highly compressed fine‑grain graphite, which dissolves only slowly in electrolytes. Unlike metallic anodes, graphite does not shed contaminating metal particles, ensuring cleaner coatings and higher deposit quality.  The 6 mm diameter rod, with an approximate length of 95 mm, fits standard plating fixtures, holders, and pen plating tools, making it easy to integrate into various electroplating setups Typical Applications Electroplating processes (e.g., silver, gold, copper, black nickel, chrome, white bronze) Pen, bath, and pad plating Activation and pre‑treatment steps Counter‑electrode or anode use in a wide range of electrolytes Situations where metal contamination must be avoided Key Benefits Chemically inert: prevents unwanted metal ion contamination in the plating bath. Versatile: compatible with most electroplating chemistries and techniques.  Slow wear: dissolves gradually, extending service life. Affordable: cost‑effective solution for frequent use.  Easy to use: fits common plating holders and pen plating tools. Material & Dimensions Material: High‑density fine‑grain graphite Diameter: 6 mm Length: approx. 95 mm (other lengths may be available)  Practical Tips Ensure electrodes are clean and free of oils before use.  Replace electrodes periodically as they slowly dissolve during electroplating. Graphite’s mild warming effect can help stabilize bath temperature during plating. Conclusion The Graphite Electrode Ø 6 mm is an effective and reliable anode/electrode for a wide range of electroplating applications. Its inert behavior, broad compatibility, and metal‑free current delivery make it a solid choice for hobbyists, workshops, labs, and professional plating operations.
