C64700 Nickel Silicon Bronze Alloy
C64700 nickel silicon bronze is a wrought alloy that has moderate strength and good corrosion resistance. Because it has a golden bronze color, it is an attractive option in a variety of applications.
Many industries use C64700, including aerospace, industrial, and railway. Common applications include:
- Nickel Silicon Bronze Bearing Cages
- Nickel Silicon Bronze Valve Guides & Valve Stems
- Nickel Silicon Bronze Fasteners
- Nickel Silicon Bronze Marine Fittings
- Nickel Silicon Bronze Pole Line Hardware
Diversified Bronze has solid and cored nickel silicon bronze bars in 144" lengths. Other lengths and non-standard sizes are available.
Technical Details
C64700 is made up of 1.6-2.2% nickel, 0.4-0.8% silicon, 0.5% zinc, and 0.1% of both iron and lead. Copper makes up the balance of the alloy. The best welding techniques include:
- Brazing
- Butt
- Coated-Shileded Arc
- Gas-Shileded Arc
- Seam
- Spot
