Introduction

None of the known implantation materials used in surgery has demonstrated a complete lack of ability to cause unwanted reactions in the human body. Nevertheless, the long clinical experience of using the material mentioned in this part of ISO 5832 has demonstrated that with the use of this material, if it is properly applied, an acceptable level of biological response can be expected.

1 area of use

This part of ISO 5832 specifies the characteristics and appropriate testing methods for a deformable titanium alloy, known as the titanium alloy 6-aluminum 7-niobium (titanium-6-Al-7-Nb) titanium alloy for use in the manufacture of surgical implants.

NOTE The mechanical properties of a sample obtained from a finished product made from this alloy do not necessarily coincide with the characteristics specified in this part of ISO 5832.

3 Chemical composition

The chemical composition of the melting must meet the requirements for the chemical composition indicated in Table 1. The analysis of the ingot can be used to identify all the mandatory chemical components, with the exception of hydrogen, which will be determined after heat treatment and etching.

Aluminum from 5.5 to 6.5
Niobium from 6.5 to 7.5

Iron maximum 0.25
Oxygen maximum 0.20
Carbon maximum of 0.08
Nitrogen maximum of 0.05

4 Microstructure

In the study according to Table 3, the microstructure consists of the alpha and beta components and corresponds to the photomicrographs A1 to A9 in the ETTC 2 publication for the annealed material.

5 Mechanical properties

The tensile strength of the alloy, determined in accordance with Article 6, shall comply with the requirements specified in Table 2.

In the event that any of the test fragments do not meet the specified requirements or are broken outside the limits of the scale of the measuring device, two more fragments representative for the same lot are likewise tested. The alloy should be considered suitable only if both additional fragments meet the specified requirements.

If one of the additional fragments does not meet the requirements, then the submitted product must be recognized as not meeting the requirements of this part of ISO 5832.

However, the manufacturer, if desired, may re-heat the material and re-submit it for testing in accordance with the requirements of this part of ISO 5832.

6 Test methods

The test methods to be used to determine compliance with the requirements of this part of ISO 5832 are shown in Table 3.

Representative test pieces for the determination of mechanical properties shall be prepared in accordance with the provisions of ISO 6892.
