    Abstract

    This specification establishes the requirements for brass strips in narrow widths and light gages produced from Copper Alloy UNS Nos. C23000, C26000, and C26130 to be used in heat exchanger tubing. The material for manufacture shall be a cast bar, cake, or slab of such purity and soundness as to be suitable for processing by hot working, cold working, and annealing to produce a uniform wrought structure in the finished product. Products shall be produced in tempers H01 (¼ hard), H02 (½ hard), O81 (annealed-to-temper, ¼ hard), and O82 (annealed-to-temper, ½ hard). Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (mass, thickness, width, and straightness), mechanical (tensile and yield strengths, and elongation), chemical composition, and grain size requirements.

    1. Scope

    1.1 This specification establishes the requirements for brass strip in narrow widths and light gages produced from Copper Alloys Nos. C23000, C26000, and C26130.

    Note 1—This product is commonly used for the manufacture of thin-wall tubes for water passages in heat exchangers for internal combustion engines and other closed system heat sources.

    1.2 UnitsThe 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.

    1.2.1 ExceptionGrain size and chemical analysis sampling are stated in SI units.
