Product Guide

🏭Application Scenarios+

This EMLM-compatible round electrode is used in EDM engraving tooling to produce character marks and small details on conductive parts. In production setups, it’s selected when you need stable electrical contact at the point of engraving and consistent reproduction of fine edges.

  • Metal character engraving (tooling plates, identification tags): The round copper tip geometry helps support controlled material removal for crisp lettering and alphanumeric content.
  • Small-type character work: For compact features, the available tip diameter (P) from 0.8 to 4 mm supports selection matched to feature size to maintain legibility.
  • EMLM type electrode systems: Use this variant when your electrode changer or holder is designed for EMLM type interfaces to streamline setup and reduce alignment variability.
🔧Material & Process Details+

The electrode is made from tough pitch copper, selected for its high electrical conductivity and favorable machinability/finishing response during electrode preparation. Tough pitch copper typically offers good performance in EDM where stable current transfer at the tip is required for clean engraving.

  • Heat treatment / state: Copper EDM electrodes are generally supplied in a conductive, work-ready condition rather than hardened as with tool steels; no quench/temper or nitriding is specified for this product.
  • Hardness & wear behavior: As a copper-based electrode, expected behavior emphasizes conductivity and engraving stability rather than extreme wear resistance associated with hardened steels.
  • Trade-off: Compared with harder copper alloys or alternative electrode materials, tough pitch copper prioritizes electrical performance and consistent engraving detail.
📐Sizing & Selection Guide+

Select the electrode tip diameter P (0.8 ~ 4 mm) based on the smallest character stroke width or feature you must reproduce in your mold/part engraving. For finer character marks, choose the lower end of the P range to better control detail; for larger strokes, increase P to maintain process stability across longer engraving paths.

  • Match to engraving depth/geometry: Use the selected character type (Standard type or Small type) together with the tip diameter to align with the expected feature scale.
  • Character set constraints: Character engraving selection supports a range of 0 ~ 9, with supported character types listed as +, /, <, >, A–Z.
  • Tolerance & fit: Because this item is specified as an EMLM type electrode, ensure your electrode holder/adapter is EMLM-compatible to maintain proper electrical contact and alignment.
  • Configurable dimensions: Only P is provided as a variable range; other character-related selections are determined by engraving count/type.

Frequently Asked Questions

What tip diameter range (P) is available for fine character engraving in EDM?+
The electrode tip diameter P is specified as 0.8 to 4 mm. For smaller, more detailed character work, engineers typically select the lower P values to better control stroke geometry.
Is this electrode limited to EMLM type electrode systems, or can it be used with other holders?+
This product is described as compatible with EMLM type electrode systems. For reliable electrical contact and stable setup, you should confirm your electrode holder/adapter is designed for the EMLM interface before use.
How do I choose between Standard type and Small type character engraving?+
The specification lists Character Type options: Standard type and Small type. Pair the character type with the smallest practical P (0.8 ~ 4 mm) to match your required feature scale and legibility.
What engraving character selection options are supported for this copper electrode?+
Supported character engraving includes 0 ~ 9. Supported character set includes +, /, <, >, and A–Z (A, B, C … Z), as listed in the product data.
What material properties should I expect from tough pitch copper, and how does it affect durability?+
The electrode uses tough pitch copper for dependable electrical conductivity and engraving stability. The data does not specify a hardened state (e.g., quench & temper, nitriding), so performance emphasis is on conductivity and fine-detail contact rather than high hardness wear resistance typical of hardened steel tooling.
