Definition

• Phosphor bronze is also called tin bronze
  because it generally contains between 0.5 to1
  tin and between 0.01 and 0.35 phosphorous. This
  combination gives the metal alloy incredible
  strength, but also fine grain, durability, high
  fatigue resistance, and a low coefficient of
  friction.
• Silicon Bronze also called red silicon bronze,
  silicon bronze contains copper, but also silicon
  and zinc. Most often, it has a zinc content of
  20, and a silicon content no greater than 6.
  The most common application is the manufacturing
  of pumps and valves parts.

Composition

• PB-This alloy typically has a tin content
  ranging from 0.5 to 1.0, and a phosphorous
  range of 0.01 to 0.35.
• SB- This is an alloy that can cover both brass
  and bronze (red silicon brasses and red silicon
  bronzes). They typically contain 20 zinc and 6
  silicon.

Nature

• PB- These alloys are notable for their
  toughness, strength, low coefficient of friction,
  high fatigue resistance, and fine grain. The tin
  content increases the corrosion resistance and
  tensile strength, while the phosphorous content
  increases the wear resistance and stiffness.
• SB- Red brass has high strength and corrosion
  resistance and is commonly used for valve stems.
  Red bronze is very similar but it has lower
  concentrations of zinc.
