Tungsten Alloy Rod in Punch

Tungsten alloy rod is high density tungsten alloy rod used for manufacturing punch in stamping, cold heading, precision blanking, and forming dies. Manufactured through powder metallurgy, CTIA’s tungsten alloy rod features high strength, excellent wear resistance, and superior impact resistance, meeting the service requirements of punches under high-frequency impact, continuous friction, and heavy-load processing conditions. As a key material for precision punches, punch pins, dies, and wear-resistant stamping components, CTIA’s tungsten alloy rod is widely used in automotive, electronics, hardware, home appliance, and precision stamping manufacturing.

1. Characteristics of CTIA’s Tungsten Alloy Rod in Punch
(1) High Density and High Strength
Delivers substantial load-bearing capacity with a density range of 16.5-18.8 g/cm³ and a tensile strength of 700-1400 MPa, enabling long-term endurance under high-frequency impact loads encountered during stamping and cold heading.
(2) Superior Wear and Impact Resistance
Possesses a dense microstructure with excellent wear and impact resistance, reducing punch wear, chipping, and deformation to extend mold service life.
(3) Favorable Toughness and Fatigue Resistance
Balances strength with structural toughness, absorbing cyclic loads generated by extended, continuous stamping operations to lower fatigue cracking risks and ensure production stability.
(4) Good Dimensional Stability
Features a low coefficient of thermal expansion, maintaining consistent dimensions under continuous processing and thermal fluctuations to preserve punching accuracy and die clearance consistency.
(5) Precision Machinability
Supports turning, grinding, and Electrical Discharge Machining (EDM) to produce punches, punch pins, and male dies of various geometries, fulfilling precision mold manufacturing requirements.

2. Applications of CTIA’s Tungsten Alloy Rod in Punch
(1) Precision Stamping Punches
Used for manufacturing punches and dies in automotive parts, electronic connectors, and hardware components, improving stamping accuracy and product consistency.
(2) Cold Heading Punches
Applied in cold heading punches for bolts, nuts, pins, and other fasteners to withstand high impact loads and extend tool service life.
(3) Progressive Die Punches
Used in punching, blanking, and forming operations of high-speed continuous stamping processes to meet high-volume production requirements.
(4) High-Strength Material Punches
Applied in punches for high-strength steel, stainless steel, and thick sheet materials, improving cutting edge wear resistance and reducing wear and burr formation.
(5) Precision Forming Punches
Used in powder metallurgy forming, fine blanking, and complex-geometry punch manufacturing to meet high-precision processing requirements.
