(Specification)Standard Specification for Titanium Sponge
Standard Specification for Titanium Sponge
ABSTRACT
This specification covers virgin titanium metal melting stock. This virgin metal is commonly designated as sponge titanium because it is most commonly porous and spongelike in texture, although metal produced electrolytically is granular and is essentially nonporous. Sponge titanium is usually prepared by reduction of titanium tetrachloride and gets its spongelike character from the processes involved in production. This spongy characteristic, however, is not considered essential and may be expected to vary greatly with manufacturing methods. For example, virgin titanium produced electrolytically is crystalline or granular in character and is essentially nonporous. The metal is usually supplied in lump or granular form. The virgin titanium shall be free of scrap, intentionally added contaminants and shall be in uniform, well-mixed blends. The titanium metal shall conform to the chemical composition and Brinell hardness requirements prescribed.
SCOPE
1.1 This specification covers the purchase of virgin titanium sponge metal. This virgin metal is commonly designated as titanium sponge because it is most commonly porous and sponge-like in texture, although metal produced electrolytically is granular and is essentially nonporous.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
