Bronze with a high lead content offers good lubricity
Commonly used in the manufacture of bushes, bearings and wear plates
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 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
SAE660 or C93200 is a Leaded (Tin) continuously cast bronze and is a standard in the industry for light/medium bearing applications. Leaded (Tin) Bronze SAE660 or C93200 is suitable for various applications under medium loads. Leaded (Tin) Bronze SAE660 / C93200 has good resistance to seawater and brine enabling it to be used in the valve and pump industry.View Details
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.View Details
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.
CA104 is wrought high strength aluminium bronze, the commonly most used bronze on the market in the UK.
Aluminium Bronze BS2874 CA104 is used for its high strength and excellent corrosion resistance to sea water and other aggressive environments. Aluminium Bronze BS2874 CA104 also has good wear and abrasive resistance the ability to withstand shock loading.
Aluminium Bronze NES833 DEFD STAN 02-833 is a nickel aluminium bronze similar to CA104 but manufactured to the requirements of the Ministry of Defence. The MOD stipulate a nickel content that exceeds the iron content to improve the general corrosion performance.View Details
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.
