Silicon Bronze Fasteners

Silicon Bronze is the metal of choice for wooden boats and any wood that is in a wet environment. Our Fasteners are Alloy 651 Silicon Bronze.
Bronze is an alloy of Brass and usually consists of 94-96% copper by weight, and the rest is typically 2.5-6% silicon and a mixture of other metals such as aluminum, zinc, lead, iron, manganese, and more.

Silicon bronze will not rust, is resistant to freshwater, saltwater, fog/mist, alkalis, acids, and organic chemicals, and is only susceptible to attack via sulfides, nitric acid, chromates, ferric chloride, and other oxidizing salts. Silicon bronze is also anti-biofouling, meaning it is inherently antimicrobial and will passively defend against the spread of marine marine boring worms, bacteria, and germs.
