GR2 Titanium Ultra-fine Wire

As an industrial-grade pure titanium specialty product featuring "medium strength + high adaptability," GR2 titanium ultra-fine wire significantly enhances mechanical strength while retaining pure titanium's corrosion resistance and ease of processing. It fully complies with international standards such as ASTM B863 . Its core advantage lies in balancing "load-bearing capacity" and "process flexibility," making it a preferred choice for customers in global industrial equipment, medical non-implant devices, and electronic communication sectors-particularly suitable for precision component production where strength requirements exceed GR1 and cost control is essential.

II. Core Advantages of GR2 Grade (Distinguished from GR1)
As the most widely used medium-strength grade among industrial pure titanium, GR2's ultrafine wire form further enhances "structural adaptability," with the following core advantages:
Strength and Ductility Balance: With a tensile strength of 345-450 MPa, it can withstand mechanical stress better than GR1 while maintaining an elongation of ≥18%.
It prevents the microstructure from being deformed but does not prevent bending and coiling which is beneficial especially for semi-structural parts such as micro-springs and support wire.
Cost advantage in mass production: Compared to titanium alloy, GR2 offers lower raw material costs and simpler processing techniques. Additionally, its diameter range can extend down to 0.3mm, supporting large-scale production and effectively reducing customers' unit procurement costs, making it suitable for industrial-grade mass applications

Typical Application Scenarios

 

1. Medical devices (non-implantable)

Surgical instruments: Used for laparoscopic tools with ultra-fine shafts, dental handpiece drive shafts, high strength ensures rigidity during operation, pure titanium material avoids tissue irritation, and complies with medical and healthcare standards.
Medical device structural components: Serving as support wires for portable ultrasound probes and diagnostic instruments, they balance lightweight properties (density of only 4.51g/cm³) with structural stability, reducing the overall weight of the equipment.

2. Electronics and Communication

5G Micro Connectors: As high frequency connector pins, they are high strength to prevent deformation under multiple plugging and pulling out, stable signal transmission, and can be adapted to the miniaturization of smart phone and the communication equipment of base station.Wearable Device Battery: Wire for high-energy-density lithium batteries, having rust resistance to suppress deterioration of electrodes and extend battery life of wearable devices (such as smart watches and fitness trackers)

3.Industry and Petrochemicals

Precision Valve Micro Spring: Applied in petrochemical pipeline control valve, meets resistance to corrosion in mild hydrocarbon media and possesses good elasticity in cyclic loading, ensures valve micro flow precision control.
Industrial Automation Sensors: As the signal transmission cable for workshop temperature and humidity sensors, it resists oil stains and damp environments in workshops, eliminating the need for frequent replacements during long-term use and reducing maintenance costs.
