Leaded (Tin) Bronze

SAE660 / C93200

  • Excellent wear resistance

  • Easily machinable

  • Free cutting

  • Good load carrying capacity and thermal conductivity

  • Bronze with a high lead content offers good lubricity

  • Commonly used in the manufacture of bushes, bearings and wear plates

Phosphor Bronze

PB1 / LB2 / LB4 / PB2

  • Hard wearing bronze containing a small amount of phosphorus

  • High fatigue resistance

  • High tin content reduces the risk of corrosion

  • Phosphorus increases wear resistance

  • Commonly used in manufacture of bearings, sleeves, thrust washers and gears

Aluminium Bronze

BS2874 / CA104 / NES833 / C63000 / C63200

  • Aluminium is the main alloying metal added to copper in contrast to standard bronze (copper/tin)

  • Higher strength and corrosion resistance compared to other bronzes

  • Resistance to corrosion in seawater

  • Commonly used in the marine sector, oil and petrochemical industries (non sparking environments)

  • Used in the manufacture of valves and fasteners

Phosphor Bronze PB1

PB1 is a continuously 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 (although wrought materials can outperform this). Also, with excellent corrosion and fatigue resistance. Phosphor Bronze PB1 can be soldered and brazed.

Leaded Bronze / Phosphor Bronze LB2 / LB4 / PB2

BS1400 : LB4 is a Leaded Bronze containing approximately 9% lead and 5% tin. Excellent machining properties, very good wear resistance and medium to good corrosion resistance.
           
LB2 continuous cast leaded tin bronze with good plasticity which maximises strength.                   

PB2 has a higher lead content than PB1 which gives an excellent resistance to wear.

Aluminium Bronze C63000 / C63200

One of the American grades of nickel aluminium bronze. Aluminium Bronze c6300 / C63200 contains around 10% aluminium, 5% nickel and 3% iron the alloy offers an inherent high strength and hardness combined with a very good toughness and an excellent resistance to wear, shock and abrasion.

Aluminium bronze C6300 / C63200 offers very good corrosion and erosion and cavitation resistance in seawater and non-oxidising acids. It also has a very good galling resistance and also offers a high retention of mechanical properties at elevated temperatures making this ideal for aerospace applications. Used typically in the Oil and Gas and Marine environments.

Aluminium bronze C63200 is a strong, corrosion resistant material that performs well at high and low temperatures. It also has a low magnetic permeability, making it ideal for use on instrumentation systems, seawater piping systems and marine propulsion units.
