Material:Ti-6Al-7Nb

Shape: Round

Regular size: Diameter 8mm-50mm

Specification: ASTM F-1295

 

Titanium Ti6Al-7Nb was developed for use in the medical and surgical device applications although its properties are nearly identical to Ti6Al4V however Niobium has been substituted for Vanadium as the beta stabilizing agent giving improved biocompatability. Ti6Al7Nb is widely used in the medical device industry.

Processing technology of Ti-6Al-7Nb

1. Smelting process: select first-class sponge Titanium, pure Aluminum, and Aluminum Niobium or Ti-Nb intermediate alloy as raw materials, mix according to nominal composition → press electrode → melt in secondary or tertiary vacuum consumable furnace to obtain qualified ingots with uniform composition, focusing on solving the uniformity of Niobium.

2. Heat treatment process: Ti-6Al-7Nb Titanium alloy is a rod alloy that is heat treated in an electric furnace. A simple annealing process is adopted to conduct heat treatment at 700℃/h with air cooling.

3.Deformation process and properties: Ti-6Al-7Nb belongs to α+β Titanium alloy, and its thermal processing process is similar to Ti-6Al-4V, and the heating temperature of general ingot is 1150 °C-1200 °C.Through hot forging, precision forging and hot rolling, the alloy is made into rods with diameters of 110mm, 60mm, 30mm, 20mm and 12mm Ti-6Al-7Nb Rod, which can meet the tensile properties and other properties specified in the technical standards (ASTM F1295) at room temperature.

Also it can be made into Ti-6Al-7Nb Sheet for medical inplant use.
