Why choose XINNUO medical titanium bars?

Xinnuo company specializes in producing medical titanium and titanium alloy material which used for orthopedic implants. Our raw material is the medical standard titanium sponges,which go through carefully selection and production processes, alloy confect, electrode suppress, three times weld melting into the special ingot billet.

The ingot billet is made by the large tonnage press. After the upsetting and drawing’s large deformation forging repeatedly, the grain is crushed fully with uniform processability. After rolled by the big pressure rolling mill, the ingot billet becomes the required different sizes of slab and bar billet.

Large diameter titanium bars (Φ25-Φ100mm) are mainly supplied by rolling state with more than 50% rolling deformation, adopting the solid solution heat treatment method to ensure material’s structure uniformity, hardness and other mechanical properties.

Small size titanium bars (diameter < Φ25mm) are produced by drawing method with more than 60% deformation amount of reducing. This operation can control compact structure, good ovality, excellent straightness, then match with effective aging heat treatment methods to eliminate the residual stress, ensure the stable and good consistency properties.

All the products go through the infra-red detection apparatus which is to ensure h7, h8 tolerance; ultrasonic flaw detection and turbine detection which is to ensure no defects in surface and interior.

All the products are supplied with vacuum annealing state which is to control detrimental element in a reasonable level.

All the products are printed to increase the traceability and establish the archives for future reference.

Our products win at 3 aspects: awareness of quality and responsibility, unique and advanced equipments and technics process, complete test control methods.

Advanced technics process contributes to consistency and stability performance.

Unique straightening and leveling equipment and high precision grinding machine ensure good straightness, high precision and degree of finish.

Infra-ray diameter gauge, ultrasonic flaw detection and eddy current flaw detector keep good internal and surface quality and high reliability.
