(Specification)Standard Specification for Aluminum and Aluminum-Alloy Seamless Condenser and Heat-Exchanger Tubes with Integral Fins
Standard Specification for Aluminum and Aluminum-Alloy Seamless Condenser and Heat-Exchanger Tubes with Integral Fins
SCOPE
1.1 This specification covers externally helical, integrally finned aluminum-alloy seamless tubes with finned or unfinned ends, with continuous fins, or with unfinned sections, in outside diameters (diameter over fins) up to 2 in. inclusive.
1.2 Alloy and temper designations are in accordance with ANSI H35.1. The equivalent Unified Numbering System alloy designations are those of Table 1 preceded by A9, for example, A91060 for aluminum 1060 in accordance with Practice E527.
1.3 For acceptance criteria for inclusion of new aluminum and aluminum alloys in this specification, see Annex A2.
1.4 A complete metric companion to Specification B404 has been developed-B404M; therefore, no metric equivalents are presented in this specification.

To determine conformance to this specification, each value for tensile strength and for yield strength shall be rounded to the nearest 0.1 ksi [1 MPa] and each value
for elongation to the nearest 0.5 %, both in accordance with the rounding method of Practice E 29.
C
These alloy and temper designations were established in accordance with ANSI H35.1.
D
Elongations in 50 mm apply for tube tested in full-section, for sheet type specimens, for tubes having a flat wall, and for similar curved specimens for tubes having
a curved wall, up to a maximum wall thickness of 12.50 mm. Elongations in 5 D (5.65 =A ), where D and A are diameter and cross-sectional area of the specimens,
respectively, apply to round test specimens machined from wall thicknesses over 6.30 mm.
