BRUSH® 1916
Overview: Brush 1916 is a heat-treatable leaded copper alloy designed for automatic screw machine applications. It offers high strength, good machinability, excellent surface finish, and consistent microstructure, making it suitable for electrical contacts, connector pins, and sockets.
Chemical Composition: The alloy consists of Nickel (0.8-1.2%), Lead (0.5-1.0%), Phosphorus (0.15-0.35%), with the balance being Copper.
Physical Properties: The density is 0.320 lb/in3 (8.88 g/cm3). It has a thermal expansion coefficient of 9.8 x 10-6 °F-1 (17.7 x 10-6 °C-1), thermal conductivity of 120 BTU/ft hr °F (210 W/m °C), and electrical conductivity of 50% IACS (29 x 106 S/m).
Mechanical Properties: Brush 1916 is available in various tempers: Annealed (A), Precipitation-hardened (AT), Hard (H), and Heat Treated (HT). Each temper offers different ranges of tensile strength, yield strength, and elongation, suitable for specific applications.
Heat Treatment: The recommended cycle is 700°F for 3½ hours. Additional information is available from Materion.
Machining: The lead content aids in chip control during machining, making it ideal for automatic machining. High-speed steel and carbide tools are recommended.
Availability: Brush 1916 is available in rod or wire, with diameters from 0.030” to 0.625”. Diameter tolerances adhere to ASTM B249 and B250 standards. Custom shapes are available upon request.
Tolerances: Detailed diameter and out-of-round tolerances are provided for both rod and wire, with additional specifications per ASTM standards.
Technical Assistance: For more information, contact Materion Performance Alloys Customer Technical Service Department.

DATA SHEET Brush® 1916 Rod and Wire... The Machinable Copper Nickel Alloy Brush 1916 is a heat-treatable leaded copper alloy engineered specifically for automatic screw machine applications. With a machinability index of 70, Brush 1916 also provides high strength, good machinability, excellent surface finish, close diameter control, and microstructural consistency. The properties of Brush 1916 make it an ideal material for machined or formed electrical contacts, connector pins and sockets. Chemical Composition (Weight %) Physical Properties Annealed Temper (A) is the softest form available for applications where maximum formability is required. Precipitation-hardened (AT) properties are obtained by heat treatment, performed by the customer, after forming.

Hard Temper (H) is cold worked to increase strength; however, formability is decreased. H temper material can also be heat treated to obtain peak (HT) properties after forming. H tempers are commonly used for cold-heading operations. Heat Treated Temper (HT) provides maximum properties after heat treatment. H temper product can be heat treated by the user to obtain HT properties. Mill hardened HT material can be purchased from Materion and is generally the most cost effective temper. Heat Treatment The recommended heat treatment cycle for Brush 1916 is 700°F for 3/ hours. Additional heat treatment...
