Silicon Bronze Nuts and Bolts
As a manufacturer of high quality nuts, bolts, and other fasteners since 1981, Atlanta Rod and Manufacturing is committed to ensuring customer satisfaction. By producing a substantial inventory of specialty materials, we work hard to provide each customer the right products for any project.
Silicon bronze is a popular material, often referred to simply as bronze. Silicon bronze, an alloy of mostly copper and tin, contains a small amount of silicon, making it a perfect choice for marine environments. Many marine professionals prefer silicon bronze fasteners over stainless or other metals because of its superior resistance to corrosion and its strength and durability. Though bronze has a higher cost than some comparative metals, silicon bronze nuts and bolts are reliable and durable.
Silicon bronze alloys should be selected based on their intended use. Specifically:
- Silicon Bronze Alloy 651, at 98.5 percent Cu and 1.5 percent Si, is typically best in cold headed parts.
- Silicon Bronze Alloy 655, at 97 percent Cu and 3 percent Si, is best used for fasteners which must be hot-made.
- Silicon Bronze Alloy 661, made up of 95 percent Cu, 3 percent Si and 0.5 percent Pb is a solid choice for parts that will require machining.
Hex bolts have a chamfered point that can aid in insertion to a tapped nut or hole, and their length should be measured from just under the head.
Benefits of Silicon Bronze Nuts and Bolts
Silicon bronze fasteners are generally preferred in wooden boat construction and woodworking because of its resistance to corrosion compared to stainless and its higher strength compared to brass. Woodworkers tend to prefer bronze over copper because of its natural beauty and appearance, which amplifies the value of handmade sea crafts while ensuring boats are structurally sound.
One of the best benefits to using silicon bronze fasteners is its corrosion resistance. Brine, sulphite solutions, and gases do not cause silicon bronze nuts and bolts to corrode or otherwise deteriorate. Because it is an alloy of superior strength that stands up to extreme conditions, silicon bronze is often chosen over stainless steel or other materials that simply won’t make the grade. For this reason, silicon bronze is commonly found in commercial applications, especially in marine industries and sewage disposal.
Additional benefits to using silicon bronze fasteners include their high degree of thermal conductivity, outstanding friction reduction, and nonmagnetic qualities. The hex head makes for easy driving, and hex bolts chamfered point add to their ease of use. They can be driven with simple wrenches from the side, requiring minimal clearance. Industrial and manufacturing experts prefer bronze fasteners, nuts, and bolts, as special machinery and equipment is not needed to aid installation.
Silicon bronze is the most popular of the bronze families. Fasteners made from silicon bronze are ideal for naval construction, especially in mine sweeping applications. To alleviate the risk of stress corrosion failure, silicon bronze nuts and bolts that are cold formed should be stress relieved to achieve best results.
In addition to their use in naval construction, silicone bronze nuts and bolts are popular in the marine industry. They are also commonly used in general construction, refineries, and the power and energy industry as well, and are similar to low carbon steel in terms of hardness and durability.
Nearly as hard as stainless steel, silicon bronze does not require atmospheric exposure to maintain corrosion resistance. As it ages, bronze will eventually appear similar to copper that has been exposed. Compared to brass fasteners, bronze is much harder and more resistant to corrosion.
Bronze is much more suited than brass or other similar components when it comes to salt water environments or for areas with extreme weather possibilities. For this reason, silicon bronze is a popular choice for decks or other outdoor projects. It is also uniquely suited to projects that involve exposure to gases and sewage.
Silicon bronze nuts and bolts are sold by the piece in a wide variety of sizes to fit nearly any project, though a 1/2” diameter is the most commonly used. No matter your need for bronze nuts and bolts, we have the largest selection of quality products and are capable of filling custom orders.
