Technological properties

Property
Application areas	Brush 1916 is a strong material to machine or form into electrical contacts, connector pins and sockets.
General machinability	The addition of lead in the Brush 1915 & Brush 1916 alloy composition allows for chip control in turning and drilling operations, making the alloy ideal for automatic machining. Brush 1915 & Brush 1916 machines readily at feeds and speeds used for other leaded copper alloys. High speed steel and carbide tools are recommended for all machining operations.
