DATA SHEETRd)HS COMPLIANT Brush® 1915 Rod and Wire... The Machinable Copper Nickel Alloy Brush 1915 is a heat-treatable leaded copper alloy engineered specifically for automatic screw machines and cold forming applications. With a machinability index of 70, Brush 1915 also provides high strength, good machinability, good conductivity, excellent surface finish, close diameter control, and microstructural consistency. The properties of Brush 1915 make it an ideal material for machined or formed electrical contacts, connector pins and sockets. Chemical Composition (Weight %) 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 1915 is 700°F for 3/2 hours. Additional heat treatment...
