Silicon bronze is a copper-silicon alloy that is often used in electrical power distribution applications. Offered in silicon bronze 655 and 651 silicon bronze, this material is more corrosion-resistant and stronger than brass.
Fastener Solutions offers ASTM B98 Alloy 651 or Alloy 655 and B99 Alloy 651 or Alloy 655. These materials are made from 95-97% copper, 2-3% silicon, and 1% manganese.
Silicon Bronze Fasteners from Fastener Solutions
Fastener Solutions carries a wide range of products that are constructed from advanced quality 655 & 651 silicon bronze. These fastener products will stand the test of time and can be used for numerous types of applications. Some of the products that we stock in this alloy include:
Silicon Bronze Bolt and Nuts Strength and Other Benefits
Silicon bronze fasteners are best known for their corrosion resistance. They can be used in gases, acids, and salts without corroding. It also offers superior strength to other metals like stainless steel and brass.
Not only does silicon bronze offer beneficial mechanical properties, but it is also used for its beautiful appearance as well.
Silicon bronze bolts and nuts also offer:
- High thermal conductivity
- Friction reduction
- Minimal clearance requirement
- Non-magnetic properties
Applications of Silicon Bronze Bolts
Silicon bronze fasteners offer a variety of properties, like corrosion resistance and high strength, that make them ideal for naval and marine applications. Silicon bronze bolts are durable against saltwater and extreme weather, making them useful for outdoor applications like deck and woodworking as well.
Silicon bronze bolts are also found in general construction projects, as well as in electrical circuitry in switchgears. They are used in valves and process control equipment, as well.
Other applications of silicon bronze fasteners include:
- Gas exposure
- Power and energy
Silicon Bronze 655 and 651 Silicon Bronze
Both silicon bronze 655 and 651 offer unbeatable strength and durability, but there are a few differences to consider when selecting a material for your application. The main difference is in their silicon content. 651 silicon bronze is a low-silicon material while 655 is a high-silicon material.
Both materials offer excellent corrosion resistance, especially against water, acids, salts, and organic chemicals. 655 Silicon bronze, however, can’t be used with sulfides, nitric acid, acid chromates, or oxidizing salts.
651 silicon bronze bolts are the standard material for yachts and many stock power boats. They are also ideal for deck hardware, water tanks, and wood screws. 655 silicon bronze is a popular engineering alloy that is more suited to pump shafts, valve stems, and traditional nuts, bolts, and screws.
