Phosphor Bronze PB2 Round Bar Manufacturer, Supplier, Stockist & Exporter from India

In general, bronze is a family of copper alloys whose majority of its composition is copper. There are two types of bronze – nickel bronze and phosphor bronze. Nickel bronze has the highest nickel content up to 30%, while phosphor bronze has the least nickel. The phosphor bronze has higher stiffness and wear resistance than its nickel bronze counterparts. Both of these materials have been found to be used in many industries, most notably in the field of musical instruments such as guitar strings. 

The elasticity of bronze allows it to be used in a variety of applications due to its versatility.

As a result of the superficial oxide formation, the metal core is prevented from further corrosion.

As a result of the copper oxide layer that forms on the surface, the bronze material has the trademark coloration associated with the material. If nickel or phosphorus are added to the surface, then the coloration and tone will differ a bit. In addition to being 10% lighter than usual stainless steels, these materials also have a higher electric conductivity than stainless steels, which makes them easier to produce, cut, form, or machine.

There has been a long tradition of using bronze materials for the creation of sculptures and shapes since ancient times. This material has been used in musical instruments for the ductility of its material. This low metal to metal friction makes the bronze material useful in making bearings and bushes because it has a low metal to metal friction. As a result of the low corrosion rate to chloride ions, bronze materials can be used in sea water as well as marine industrial settings.

In addition to offering good shock resistance, PB2 Phosphor Bronze offers good strength and machinability, as well as good corrosion resistance.

It is a grade of leaded bronze that complies with British Standard BS1400: PB2. With a higher tin content than PB1, this grade has even better corrosion resistance. The addition of around 9% lead and small amounts of phosphorus makes it even harder and more durable. There is also a greater resistance to fatigue.

There are plenty of applications for PB2. It is used to create materials that are similar to those made from PB1, except that they have a higher wear resistance and are subjected to higher loads.

With increased tin content when compared to PB2, phosphor bronze alloys benefit from excellent wear resistance. In addition to its high strength, the product is also highly machinable. A good corrosion resistance is also a feature of the product, particularly when used in saltwater or brine environments. In addition to its common use in pump, valve components and bearings that are subjected to medium to high loads and speeds, PB2 is often referred to as a ‘gear bronze’.
