Edm brass wire 1. High tolerant wire diameter (tolerance is within 0.001mm ) 2. Stable tensile strength: hard wire: 900-1100n/w, semi-hard wire: 700-850n/w, soft wire:400-650n/w 3. Outstanding straightness: straight wire free twisting or deformation. 4. High quality material :cuzn37, cuzn65 5. Packing which protects quality and performance: wrapped by anti-rust paper and plastic film to avoid oxidation and corrosion. 6. Higher machining speed can be achieved and also higher accuracies Spool sizes: din125, din160, din200, p3, p5, p10 Wire sizes: 0.10mm , 0.15mm , 0.20mm , 0.25mm , 0.30mm Packed in cartons
