What are the properties of phosphor bronze?
Here are some of the traits Phosphor Bronze is well-known for:
- Very good resistance to corrosion and fatigue.
- Good electrical conductivity.
- Very good product for strength performance.
- Low coefficient of friction.
- Fine grain.
- Excellent elasticity.
What is the composition of phosphor bronze?
Phosphor bronze, or tin bronze, is a bronze alloy that contains a mixture of copper with 0.5-11% tin and 0.01-0.35% phosphorous. Phosphor bronze alloys are primarily used for electrical products because they have superb spring qualities, high fatigue resistance, excellent formability, and high corrosion resistance.
What is the difference between PB1 and PB2 bronze?
Phosphor bronze PB2 (BS 1400 1985 PB2) is a phosphor bronze with a higher tin content than PB1, which means it has excellent resistance to wear. As a result of these properties, PB2 is an ideal material for the manufacture of components such as gears and heavy sliding or reciprocating loads.
How strong is phosphor bronze?
| Mechanical Properties | Metric | English |
|---|---|---|
| Tensile yield strength | 380-450 MPa | 55100-65260 psi |
| Modulus of Elasticity | 110 GPa | 16000 ksi |
| Electrical conductivity (relative to pure copper) | 15% | |
| Hardness (Rockwell B) | 75-85 |
What is leaded tin bronze?
The lead content in these bronze alloys is between 7 percent and 15 percent. High leaded tin bronzes alloys are free cutting and retain favorable thermal conductivity and good lubricity due to the lead content. Alloy C93200 is considered this family’s workhorse alloy and is widely used in many bearing applications.
What happens when phosphorus is added to bronze?
The phosphor bronzes contain between 0.5 and 11% tin and 0.01 to 0.35 % phosphorous. The addition of tin increases the corrosion resistance and strength of the alloy. The phosphorous increases the wear resistance and stiffness of the alloy.
Is phosphor bronze harder than steel?
Phosphor bronze has a decently high elastic modulus (almost half that of most steels), which suggests it is not as strong as other alloys but can hold its own under moderate conditions.
What is Phosphor bronze PB1?
PB1 is a cast material containing 10-12% tin and small amounts of phosphorus. Phosphor Bronze PB1 has high mechanical strength and has good conductivity and wear resistance. Also, with excellent corrosion and fatigue resistance. Phosphor Bronze PB1 can be soldered and brazed. The Global Bronze Expert +44 (0) 113 271 8711 Products
Phosphor bronze is an alloy of copper with 0.5–11% of tin and 0.01–0.35% phosphorus. The tin increases the corrosion resistance and strength of the alloy. The phosphorus increases the wear resistance and stiffness of the alloy. These alloys are notable for their toughness, strength, low coefficient of friction,…
What is Pb2 leaded bronze?
Phosphor Bronze PB2 This grade of leaded bronze complies with British Standard BS1400: PB2. The tin content is higher than PB1 so it has even more resistance to corrosion. The addition of around 9% lead and a small amount of phosphorus makes it even more hard wearing.
What is PB1 made of?
PB1 is a cast material containing 10-11.5% tin and small amounts of phosphorus. Phosphor Bronze PB1 has high mechanical strength and has good conductivity and wear resistance . Also, with excellent corrosion and fatigue resistance.
