EDM Wire Cutting Blanking & Forming Tools, Carbide Blanks, Carbide Preform Stripper, Carbide Ring.
We offer corrosion resistant carbide suitable for EDM, providing you with high quality solutions.
Our tungsten carbide is designed for various punching materials, including: silicon steel sheet, SPCC, iron strip, beryllium copper strip, stainless steel, and beryllium copper.
It has received unanimous praise from the stamping die company for products such as motor cores, EI cores, LED brackets, lead frames, connectors and connectors, and has been unanimously recommended by OPG(Optical profile grinder) parts processing plants.Material advantages: high hardness, high strength, high wear resistance, sharp cutting edge, suitable for precision high-speed progressive dies with stamping speed of SPM300-2000 per minute or more.

Tungsten Carbide Technology

• Corrosion resistant tungsten carbide EDM block.
• Add chromium, tantalum and other complex carbides to enhance the double grain tungsten carbide wear resistance and better impact resistance – longer life.
• Cold isostatic pressing + HIP sintering (1450°C) for more uniform density – more stable.
• Tempering + deep cold treatment (-200 degree Celsius), less stress – avoid cracking.
• Double endface grinding treatment to reduce wire cut cracking due to sintered microcracks.

Explanation of EDM Block Grades

We use primary tungsten carbide powder, unlike other carbide manufacturers, which guarantees the highest quality of tungsten carbide throughout the entire machining process and maximises consistent performance for the end user.

Corrosion-resistant binder grades optimised for WEDM processes Excellent wear resistance and high edge sharpness.

YF series

Composition: 10%-16.5% cobalt binder with submicron grain structure for stamping tools is designed for heavy-duty applications. It has a medium cobalt content and a blended tungsten carbide powder grain size for enhanced impact resistance, improved vibration resistance and corrosion resistance. This reduces corrosion and debris on the finished carbide surface.

Applications: Stamping dies for laminations, spring steel stampings, coining dies, motor cores, silicon steel sheets and high speed metal stampings.

YA series

Composition: 12%-15% corrosion-resistant binder mix with submicron grain structure, good general properties and toughness, medium cobalt and fine grain hard material. High wear resistance and good chipping resistance. Good electrical machinability.

Applications: YA series is ideal for high-speed stamping of SPCC, steel strip, beryllium copper strip and 304 stainless steel electronic components.
This series is well known in the leadframe and connector industries and is therefore recommended for PG component manufacturing.

lead frames, connectors, LED holders, high speed precision stampings.

YU series  

Composition: 10%-12% corrosion-resistant binder with 0.4-0.8μm submicron grain structure. Very good wear resistance with high edge sharpness.

Applications: grades for case stretching dies, such as electric car battery case 18650 21700, 46800, round or square. Also suitable for micro motor case stretching die.
