Application areas

Brush 1915 is an ideal material for machined or formed 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.
