Scope

1.1 This specification covers the requirements for four classes of machinable, high-density tungsten base metal produced by consolidating metal powder mixtures, the composition of which is mainly tungsten. This material specification may be used for bare parts or for parts that may be coated with other materials for protection against corrosion and abrasion.

1.2 Intended Use—Parts made from this material are intended for uses such as weights or counter-balances in static or dynamic balancing, high-speed rotating inertia members, radiation shielding, hypervelocity impact, and vibration-damping applications.

1.3 Special Applications—For particular applications, properties or requirements other than those specified in Sections 5, 6, and 7 of this specification may be important. These alloys may contain elements which make them magnetic. Where freedom from magnetic response is required, this should be specified in the purchase order. Class 4 is not available in a non-magnetic grade. For purposes of this specification, non-magnetic material is defined as material having a maximum magnetic permeability of 1.05 (see Test Method B193). Also for special applications involving large sections, methods for determining internal quality, such as mechanical tests on specimens from these larger sections or suitable nondestructive tests may be applied. If required, these additional tests shall be specified in the purchase order.

1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
