What is phosphor bronze used for?
Phosphor bronze is used for springs, bolts, bushings and bearings, electrical switches with moving or sliding parts, dental bridges, the reed component of organ pipes and various other products or assemblies where resistance to fatigue, wear, and corrosion are required (e.g., ship’s propellers in a marine environment).
Is phosphor bronze a specification?
Overview. Phosphor Bronzes, or tin bronzes, are alloys containing copper, tin and phosphorous. 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.
Is phosphor bronze a good conductor?
Phosphor Bronze is a non-magnetic metal with excellent strength and resistance to corrosion and fatigue. It holds up exceptionally well to wear. It offers good electrical conductivity, low-friction and excellent elasticity.

Is phosphor bronze self-lubricating?
The material’s strength and corrosion resistance are similar to PB102. The addition of 4% lead, dispersed throughout the matrix, enables excellent self-lubrication which makes the alloy highly suitable for bearing bushes and many applications where full lubrication cannot be assured.
What is the tensile strength of bronze?
about 550 MPa
Ultimate tensile strength of aluminium bronze – UNS C95400 is about 550 MPa. Ultimate tensile strength of tin bronze – UNS C90500 – gun metal is about 310 MPa.
Is Glass an elastic material?
Glass is a perfectly elastic material: it does not exhibit permanent deformation, until breakage. However it is fragile, and will break without warning if subjected to excessive stress.
How can you tell the difference between brass and phosphor bronze?
While brass is valued for its malleability, phosphor bronze lends a greater hardness. As a harder metal, phosphor bronze has a higher melting point than brass. Some of the key properties of phosphor bronze are corrosion resistance, fatigue resistance, and excellent elasticity.
Is phosphor bronze soft?
While brass is hailed for its malleability, phosphor bronze yields a greater hardness. As a softer metal, brass has a lower melting point than either phosphor bronze or copper.
What is glass mechanical properties?
The density of glass is 2.5, which gives flat glass a mass of 2.5kg per m2 per mm of thickness, or 2500 kg per m3. The compressive strength of glass is extremely high: 1000 N/mm2 = 1000 MPa. This means that to shatter a 1cm cube of glass, it requires a load of some 10 tonnes.
What are the 6 physical properties of glass?
