BRUSH 1915 ALLOY FOR CHALLENGING ENVIRONMENTS
Materion’s Brush 1915® material (UNS C19150) is a leaded nickel-copper alloy that provides high strength and good machinability with superior conductivity, excellent surface finish, close diameter control and microstructural consistency.
Brush 1915 is also a free machining alloy, offering high levels of machinability without harming performance and keeping overall costs low for volume specific processes such as cold heading or cold forming.
ADVANTAGES OF FREE MACHINING LEADED NICKEL-COPPER ALLOYS
Brush 1915 was developed with a unique precipitation hardening process, which enables a number of advantages, including:
- High tensile strength and yield strength
- Exceptional resistance to stress
- Excellent machinability (70 percent of free-cutting brass)
- Great cold headability
- Excellent surface finish
- Superior conductivity
- Close diameter control
- Microstructural consistency
These property combinations and benefits make Brush 1915 alloy a good alternative for copper beryllium alloys used in machined or electrical contacts, connector pins and sockets.
