EDM Wire

Tamra’s EDM Wire is precisely engineered for cutting metals via electric discharge machining. Produced through strict process control—from casting through drawing and continuous annealing—these wires deliver unmatched tensile strength, diameter precision, and straightness.

Applications

Metal cutting in tooling and die-making via EDM spark erosion

Automatic high-speed wire-cut systems requiring precision

Types & Sizes

Material Types:
- Plain Brass (uncoated; CuZn37 / CuZn35 / CuZn40)
- Zinc-coated (enhanced release / cutting speed)
- Diffused (heat-treated, gamma-phase)
Sizes: Standard wire diameters of 0.15 mm, 0.20 mm, 0.25 mm

Specification

Type	Hardness	Tensile Strength	Elongation	Conductivity	Notes
Plain Brass	Hard	~950–1050 N/mm²	< 3%	Standard	High straightness
Zinc-coated	Semi-hard	~650–750 N/mm²	~21%	Standard	Reduced breakage, speed gain
Diffused Coating	Hard	High	-	-	Premium precision performance

Diameter tolerance: ±0.000 / -0.002 mm
Smooth, flaw-free surface for reliable performance

Key Features

Exceptional diameter precision for consistent spark path
Superior straightness for minimal deviation in EDM
Coated variants (Zinc, Diffused) offer faster, cleaner cutting
Lower wire breakage and brass powder sticking during machining
