Raw material selection:

The ingots used for the production and processing of materials shall be smelted in a vacuum consumable electric arc furnace or EB furnace smelting and vacuum consumable electric arc furnace smelting, and the number of smelting shall not be less than twice.

Precautions for medical titanium rods:

The chemical composition of the product meets the requirements of the corresponding brand in the medical standard, and the H content in pure titanium, TC4 and TC4ELI should not exceed 0.010%. When the buyer re-inspected, the allowable deviation of chemical composition should comply with relevant regulations.

Dimensions and allowable deviations The dimensions of the product should be measured with corresponding precision measuring tools, and the positive and negative tolerances should be guaranteed according to customer requirements.

The grade 23 titanium bar is annealed and polished, meets International ASTM F136 specifications, and has a standard tolerance. The grade 23 titanium alloy, also known as Ti 6Al-4V ELI, offers high toughness and moderate wear resistance, along with corrosion resistance, high strength, and good formability. The material has been annealed, a method of heating and cooling metal to modify its properties, such as increasing its formability and toughness or decreasing its strength, after it has been shaped.

Titanium and its alloys, due to a successful combination of high strength, sufficient technological properties, small density and good corrosion resistance are gaining wider application for medical implants production. The application of titanium alloys for surgical implants, micro instruments and also sets of microsurgical instruments in combination with stainless steels is most expedient.

Engineered for Unmatched Medical Performance

Our titanium bars are designed specifically for demanding environments, including medical implants and surgical tools. With high tensile and yield strengths, excellent elongation, and corrosion resistance, they assure safety and longevity inside the human body. The precise tolerances and polished finish ensure compatibility with strict medical standards, while the non-magnetic property makes them suitable for MRI environments.


Versatility Across Medical Applications

From bone screws to surgical instrument handles, these titanium bars are versatile in application. Their biocompatibility and mechanical properties allow for use in both temporary and permanent implants. As manufacturers, suppliers, and exporters in India, we provide these bars in custom lengths and diameters to meet the specific needs of medical device manufacturers.
