MATERIAL SPECIFICATION

AMS4596™

REV. B

Issued 2002-11

Revised 2010-12

Reaffirmed 2018-05

Superseding AMS4596A

Copper Nickel Tin Alloy, Bars and Rods

77Cu – 15Ni – 8Sn

Solution Annealed and Spinodal Hardened (TX 00)

(Composition similar to UNS C72900)

RATIONALE

AMS4596B revises condition (3.2) and quality (3.5.1, 4.3.1.4), and removes tubes as an applicable product form. This

alloy in the form of mechanical tubing is specified by AMS4598.

1. SCOPE

1.1 Form

This specification covers a copper-nickel-tin alloy in the form of bars and rods. When tube is ordered to AMS4596, it shall

be supplied to AMS4598.

1.2 Application

These products have been used typically for parts requiring high strength, wear resistance, and corrosion resistance at

moderate temperatures, but usage is not limited to such applications.

2. APPLICABLE DOCUMENTS

The issue of the following documents in effect on the date of the purchase order forms a part of this specification to the

extent specified herein. The supplier may work to a subsequent revision of a document unless a specific document issue

is specified. When the referenced document has been cancelled and no superseding document has been specified, the

last published issue of that document shall apply.

ASTM E 8/E 8M Tension Testing of Metallic Materials

ASTM E 18 Rockwell Hardness of Metallic Materials

ASTM E 478 Chemical Analysis of Copper Alloys

3. TECHNICAL REQUIREMENTS

3.1 Composition

Shall conform to the percentages by weight shown in Table 1, determined by wet chemical methods in accordance with

ASTM E 478, by spectrochemical methods, or by other analytical methods acceptable to the purchaser.

TABLE 1 - COMPOSITION

Element (3.1.1) min max

Nickel (+ Cobalt) 14.5 15.5

Tin 7.5 8.5

Iron -- 0.50

Zinc -- 0.50

Manganese -- 0.30

Columbium -- 0.10

Magnesium -- 0.15

Lead -- 0.02

Copper (3.1.2) remainder

Copper + sum of

Named Elements (3.1.3) 99.5

3.1.1 These composition limits do not preclude the presence of other elements. Limits may be established and analysis

required for unnamed elements by agreement between the manufacturer or supplier and purchaser.

3.1.2 Copper may be reported as “remainder”, or as the difference between the sum of results for all elements and

100%, or as the result of direct analysis.

3.1.3 When all the elements in the table are analyzed, the sum shall be 99.5% minimum, but such determination is not

required for routine acceptance of each lot.

3.2 Condition

Input material is vertically continous cast, hot worked by extrusion or forging and, if necessary, cold finished. Thermal

treatments include solution annealing followed by spinodal hardening to the TX00 temper (See 8.2).

3.3 Heat Treatment

Product shall be heat treated as follows; pyrometry shall be in accordance with AMS2750.

3.3.1 Solution Annealing

Heat within the range 1450 to 1600 °F (788 to 870 °C), hold at heat for 45 to 360 minutes and water quench in room

temperature water.

3.3.2 Spinodal Hardening

Heat to 600 to 800 °F (315 to 425 °C), hold at heat for a total time at temperature greater than 1 hour and less than

10 hours, depending on section thickness to meet the property requirements of 3.4, then air cool or quench (TX 00

temper, see 8.2).

3.4 Properties

The product shall conform to the following requirements:

3.4.1 Tensile Properties

Shall be as shown in Table 2, determined in accordance with ASTM E 8/E 8M.

TABLE 2 - MINIMUM LONGITUDINAL TENSILE PROPERTIES (BARS, RODS)

Nominal Thickness

Between Parallel Sides

(bars, rods) Ultimate

Tensile Strength Yield Strength

(at 0.2% offset) Elongation in 4D

Up to 4.249 inches (108 mm), incl 132 ksi (910 MPa) 107 ksi (738MPa) 9.5%

4.250 to 8.500 inches (108 to 216 mm), incl 127 ksi (876 MPa) 108 ksi (745MPa) 3%

3.4.2 Hardness

Bars and rod 1.00 inch (25.4 mm) and over in nominal diameter or least distance between parallel sides shall have a

minimum hardness of 30 HRC, or equivalent (See 8.5) determined in accordance with ASTM E 18.

3.5 Quality

The product, as received by purchaser, shall be uniform in quality and condition, sound and free of foreign materials and

from imperfections detrimental to the usage of the product.

3.5.1 Soundness

When specified, the product shall be ultrasonically inspected to a specification and acceptance criterion agreed upon by

the purchaser and supplier (See 8.7).

3.6 Tolerances

Shall be in accordance with ASTM B 249/B 249M.

Straightness as measured by maximum depth of arc along any longitudinal surface or edge shall not exceed 1/4 inch

(6.35 mm) (for product length less than 10 feet (3.05 m)) or 1/2 inch (12.7 mm) (for product 10 feet (3.05 m) or longer).
