Si Bronze Screws and C65100 Carriage Bolts manufacturer in ISO metric and Unified Thread

Silicon Bronze Fasteners are usually selected in woodworking and wooden boat construction because its corrosion resistance and strength compared to stainless are higher. It is a low-lead brass alloy that is generally composed of 96% copper. It is known for attractive surface finish and easy pouring ability as well as a superior corrosion resistant makeup, even when submerged in liquids including fresh water, salt water, organic chemicals and most acids. Silicon Bronze Bolts are reliable and durable. 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 durability and hardness. Silicon Bronze Screws has superior strength that stands up to extreme conditions, it is frequently chosen over stainless steel screws or other materials. Due to this reason, it is commonly found in commercial applications, particularly in sewage disposal and marine industries. Silicon Bronze Nuts has high degree of thermal conductivity, outstanding friction reduction, and nonmagnetic qualities. Silicon Bronze Threaded Rod does not require atmospheric exposure to maintain corrosion resistance. As it ages, bronze eventually appear similar to copper that has been exposed. As compared to brass threaded rod it is much harder and more resistant to corrosion. Silicon Bronze Nuts and Bolts are popular in the marine industry. It is much more suited than brass or other similar components when it comes to salt water environments or for areas with extreme weather possibilities. Silicon Bronze Hex Bolts is a popular choice for decks or other outdoor projects. It is particularly suited to projects that involve exposure to sewage and gases.
