Brass are alloys of Copper and Zinc. They also contain small amounts of other alloying elements to impart advantageous properties. Brass have high corrosion resistance and high tensile strength. They are also suited to fabrication by hot forging. Free machining grades of brass set the standard for machining by which other metals are compared.Brass is one of the most-used materials in the world. The term brass generally applies to alloys of copper where the main alloying ingredient beside copper is zinc. Other alloys of copper where the main alloying ingredient is tin are usually referred to as bronze.
Brass is generally known for several things – decent strength and electrical conductivity, it can be polished easily, and there seems to be a brass for just about every application. With few exceptions, most notably C23000 Red Brass and C77000 Nickel Silver, materials in this category generally are yellow in color. Brass is the term used for alloys of copper and zinc in a solid solution. Brass has a yellow color, somewhat similar to gold and is resistant to tarnishing.
Brass is the generic term for a range of copper-zinc alloys with differing combinations of properties, including strength, machinability, ductility, wear-resistance, hardness, colour, antimicrobial, electrical and thermal conductivity, and corrosion resistance.
Brass set the standard are available in a very wide variety of product form and sizes to allow minimum machining to finished dimension. Brass does not become brittle at low temperature like mild steel. Brass also has excellent thermal conductivity making it a first choice for heat exchanger. Its electrical conductivity ranges from 23 to 44% that of pure copper.

Units—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.
The following safety hazards caveat pertains only to the test methods portion, Section 19, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limita- tions prior to use.

C60800, C61300, C61400, and C68700 be subjected to a stress-relieving thermal treatment subsequent to straightening. If required, this must be specified on the purchase order or contract. Tolerances for roundness and length, and the condi- tion of straightness, for tube so ordered, shall be to the requirements agreed upon between the manufacturer and the purchaser.
Mechanical Properties
Material specified to meet the requirements of the ASME Boiler and Pressure Vessel Code shall have tensile properties as prescribed in Table 2 or Table 3.
Grain Size for Annealed Tempers
Grain size shall be a standard requirement for all product in the annealed (O61) temper.
Samples of annealed-temper tubes selected for test shall be subjected to microscopical examination per Test Methods E112 at a magnification of 75 diameters and shall show uniform and complete recrystallization.
Products other than of Copper Alloy UNS Nos. C19200 and C28000 shall have an average grain size within the limits of 0.010 to 0.045 mm. These requirements do not apply to tubes of light-drawn (H55), hard-drawn (H80), hard-drawn and end-annealed (HE80), or drawn and stress-relieved tem- pers (HR50).
Expansion Test
Tube specimens selected for test shall withstand the expansion shown in Table 4 when expanded in accordance with
Test Method B153. The expanded tube shall show no cracking or rupture visible to the unaided eye.
Hard-drawn tubes not end annealed are not subject to this test. When tubes are specified end annealed, this test is required and shall be performed on the annealed ends of the sampled tubes.
Tubes for ferrule stock are not subject to the expansion test.Flattening Test
Test Method—Each test specimen shall be flattened in a press at three (3) places along the length, each new place to be rotated on its axis approximately one third turn from the last flattened area. Each flattened area shall be at least 2 in. in length. A flattened test-specimen shall allow a micrometer caliper set at three (3) times the wall thickness to pass freely over the flattened area. The flattened areas of the test specimen shall be inspected for surface defects.
During inspection, the flattened areas of the test- specimen shall be free of defects, but blemishes of a nature that do not interfere with the intended application are acceptable.
Tubes for ferrule stock are not subject to flattening test.
Residual Stress Test
A residual stress test, when specified in the purchase order, is required only for Copper Alloy UNS Nos. C23000, C28000, C44300, C44400, C44500, C60800, C61300, C61400, and C68700 and when not supplied in an annealed temper.

Unless otherwise specified, the producer shall have the option of testing the product to either the mercurous nitrate test, Test Method B154, or the ammonia vapor test, Test Method B858, as prescribed below.
- Mercurous Nitrate Test:
- Warning—Mercury is a definite health hazard and therefore equipment for the detection and removal of mercury vapor produced in volatilization is recommended. The use of rubber gloves in testing is advisable.
- The test specimens, cut 6 in. [150 mm] in length, shall withstand without cracking, an immersion in the standard mercurous nitrate solution prescribed in Test Method B154. The test specimen shall include the finished tube end.
- Ammonia Vapor Test:
- The test specimens, cut 6 in. [150 mm] in length, shall withstand without cracking ,the ammonia vapor test as prescribed in Test Method B858. For the purposes of this specification, unless otherwise agreed between purchaser and supplier, the risk level identified in the Annex of Method B858, shall be specified as risk level (pH value) of 10.
Nondestructive Testing
Each tube shall be subjected to the eddy-current test in
13.1.1. Tubes may be tested in the final drawn, annealed, or heat-treated temper or in the drawn temper before the final anneal or heat treatment unless otherwise agreed upon by the supplier and the purchaser. The purchaser may specify either of the tests in 13.1.2 or 13.1.3 as an alternative to the eddy-current test.
Eddy-Current Test—Each tube shall be passed through an eddy-current testing unit adjusted to provide information on the suitability of the tube for the intended application. Testing shall follow the procedures of Practice E243.
The depth of the round-bottom transverse notches and the diameters of the drilled holes in the calibrating tube used to adjust the sensitivity of the test unit are shown in Tables 5 and 6, and Tables 7 and 8, respectively.
Tubes that do not actuate the signaling device of the eddy-current tester shall be considered to conform to the requirements of this test. Tubes causing irrelevant signals because of moisture, soil, and like effects may be reconditioned and retested. Such tubes, when retested to the original test parameters, shall be considered to conform if they do not cause output signals beyond the acceptable limits. Tubes causing irrelevant signals because of visible and identifiable handling marks may be retested by the hydrostatic test prescribed in 13.1.2, or the pneumatic test prescribed in 13.1.3. Tubes meeting requirements of either test shall be considered to conform if the tube dimensions are within the prescribed limits, unless otherwise agreed upon between the manufacturer and the purchaser.
Hydrostatic Test—Each tube shall stand, without showing evidence of leakage, an internal hydrostatic pressure sufficient to subject the material to a fiber stress of 7000 psi [48 MPa] as determined by the following equation for thin hollow cylinders under tension. The tube need not be tested at a hydrostatic pressure of over 1000 psi [7.0 MPa] unless so specified.

where:
P = hydrostatic pressure, psig [MPa];
t = thickness of tube wall, in. [mm];
D = outside diameter of the tube, in. [mm]; and
S = allowable stress of the material, psi [MPa].
Pneumatic Test—Each tube shall be subjected to an internal air pressure of 60 psig [400 kPa], min, for 5 s without
