Overview

ISO 13092:2012 is an international standard established by the International Organization for Standardization (ISO) that specifies the essential properties of titanium sponge used in producing malleable materials and castings. This standard ensures consistent quality, chemical composition, and hardness parameters for titanium sponge, which is a porous form of metallic titanium serving as a crucial raw material for titanium metal production. The standard applies primarily to titanium sponge manufactured through magnesium or sodium reduction methods, facilitating uniformity and reliability in subsequent metal processing.

Key Topics

• Titanium Sponge Definition
  A porous, sponge-like form of metallic titanium utilized as the melting stock for manufacturing titanium materials.

• Manufacturing Methods

  • Magnesium Reduction Method: Reduction of titanium tetrachloride using metallic magnesium, followed by distillation and crashing.
  • Sodium Reduction Method: Reduction of titanium tetrachloride using metallic sodium, followed by leaching and drying.

• Classification and Symbols
  Titanium sponge is classified into Classes 0 to 5, each identified by specific symbols such as TS-100 M or TS-105 S, indicating the class and manufacturing method (M for magnesium reduction, S for sodium reduction).

• Chemical Composition Requirements
  The chemical composition limits detailed in ISO 13092:2012 control the maximum allowable contents of elements such as iron, chlorine, manganese, magnesium, sodium, silicon, nitrogen, carbon, hydrogen, and oxygen, ensuring high-purity titanium sponge with a minimum titanium content typically above 98.5%.

• Hardness Specifications
  The Brinell hardness of titanium sponge is regulated according to ISO 6506-1, ranging from a maximum of 100 HBW for Class 0 to maximum 200 HBW for Class 5, correlating with varying intended applications.

Applications

• Titanium Metal Production
  Titanium sponge serves as the key raw material in melting furnaces for producing various titanium and titanium alloy products used in aerospace, medical implants, chemical processing, and automotive industries.

• Malleable Materials
  High-quality titanium sponge ensures the production of malleable titanium metals with desirable mechanical properties for forming and machining.

• Casting and Alloying
  In casting operations and alloy manufacturing, titanium sponge of controlled purity and hardness facilitates optimal metallurgical properties and enhances product performance.

Related Standards

• ISO 6506-1
  Metallic materials – Brinell hardness test – Part 1: Test method. This standard defines the Brinell hardness testing procedure referenced by ISO 13092 for assessing the hardness of titanium sponge.

• ISO/TC 79 / SC 11
  Technical committee and subcommittee responsible for standards on light metals and titanium alloys, under which ISO 13092 was developed.

• Standards on Titanium Alloys
  Additional ISO standards covering specifications and testing methods for titanium alloys complement the classifications outlined in ISO 13092.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 13092 was prepared by Technical Committee ISO/TC 79, Light metals and their alloys, Subcommittee
SC 11, Titanium.
