Brush 1915 UNS Number C19150

Additional Alloys

Brush 1915 UNS Number C19150

Brush 1915 by Materion Brush Performance Alloys is a heat-treatable leaded copper alloy engineered specifically for cold heading operations and automatic screw machine applications.

Advantages/benefits of Brush 1915

Brush 1915 leaded nickel copper alloy is a unique precipitation hardening alloy containing copper, lead, nickel and phosphorus which provides high strength.  It is used for its high corrosion resistance, high tensile and yield strength with good resistance to stress.  This leaded nickel copper alloy is  a successful  alternative to beryllium copper alloys  in many applications where high strength and  corrosion resistant alloys are needed.   

The Machinable Copper Nickel Alloy

With a machinability index close to 70% that of free-cutting brass, Brush 1915 /C19150 provides excellent machinability with high strength.

Other key Advantages include:

  • xcellent cold headability
  • Good conductivity
  • Close diameter control
  • Microstructural consistency  
  • Excellent surface finish

Brush 1915 / C19150 Leaded Nickel Copper Alloy Composition

  • Nickel - 0.80 to 1.2 %
  • Lead - 0.5 to 1.0%
  • Phosphorous - 0.15 to 0.35%
  • Copper – balance
