Bronze Fasteners
Bronze Bolts, Screws, Nuts & Washers
Bronze Fasteners are often mistaken for Brass as they share many similarities in terms of colour and composition. They are both classed as “red metals” due their high Copper content and red tint, with Bronze featuring a duller gold appearance. Modern Bronze typically consists of 88% Copper and 12% Tin, but different alloys can include quantities of other metal, metalloid and non-metal elements such as Lead, Nickel, Zinc, Aluminium, Phosphorus and Silicon.
Bronze components are strong and offer good corrosion resistance due to the high levels of Tin – further increased with the addition of Zinc. The high levels of Copper can result in oxidation of the outer layer when exposed to air, which prevents damage to the interior metal and increases corrosion resistance. However, if Copper Chloride forms, this can result in “Bronze disease” – a destructive process that occurs when Copper-based alloys come into contact with chloride solutions.
Bronze has a melting point of roughly 950°C and is a better conductor of heat and electricity than most types of steel – widely found in electrical applications as a result. Bronze Fasteners are typically non-magnetic, but alloys that contain Nickel or Iron may provide magnetic properties. Alloys with modest amounts of Lead, also known as Bearing Bronzes, offer anti-friction properties at the expense of some strength – often utilised as bushings and bearings.

Phosphor Bronze Bolts, Screws, Nuts & Washers
Phosphor Bronze is family of a copper based alloys typically composed of up to 11% Tin and a small quantity of Phosphorus. Most types feature additional elements such as Iron, Zinc and Lead.
The origins of Phosphor Bronze, or Phos Bronze, date back over 100 years where it was often used in the creation of ship propellers and a range of musical instruments.
It is well known for its high strength and strong corrosion resistance, while also providing a relatively high melting point and a low coefficient of friction.
Modern uses of Phosphor Bronze include components within electrical devices due to their non-magnetic properties, as well as coastal or marine applications.
Phosphor Bronze screws, fasteners and fixings can be supplied in various grades which all differ slightly in terms of composition and performance.
Fastenright can supply parts in grades C510, C519, C521, C544, PB1, PB2, PB3, PB101, PB102, PB103 and PB104.

Silicon Bronze Bolts, Screws, Nuts & Washers
Silicon Bronze fasteners are known for their corrosion resistance, and they are often found in naval construction because of this. Brine, sulphite solutions and gases to not cause silicon bronze to deteriorate or corrode.
They are generally used in woodworking and the construction of wooden boats and preferred over the likes of copper due to its natural beauty – which in turn enhances the value of sea crafts.
It can be found in sewage disposal too.
In some instances, they can be used in general construction, refineries, and the power and energy industry.
In marine settings, silicon bronze fixings are favoured over stainless or other metals due to its superior resistance to corrosion, strength and durability. The alloy contains copper, tin and a small amount of silicon.
