Made from copper, brass, or enhanced with specialized coatings, HWA’s EDM wires deliver high and reliable performance—every cut, every time

HWA Hi-End Brass & AOI Technology

At HWA, we combine world-class metallurgy with next-generation digital inspection to deliver the highest EDM Brass wire on the market. Hi-End Brass is our flagship, engineered for all EDM machines and especially recommended for Japanese equipment.

Produced from a very pure 60/40 brass alloy, it delivers outstanding surface quality, stable cutting performance, and exceptional machining consistency.

To guarantee uncompromised quality, every spool of Hi-End Brass is certified by our in-line Automatic Optical Inspection (AOI) system, resulting in high-precision parts with outstanding surface finish.

AOI — 100% Digital Surface Certification

  • Real-time 360° surface inspection on high-speed production lines
  • Ring-camera architecture scanning the full wire circumference
  • Detects scratches, blisters, die marks, particles, and micro-dents
  • Only fully inspected spools are released to customers

One Promise: Zero Compromise on Quality

This is not standard brass wire — this is Hi-End Brass

This is HWA.
