 Nickel Bronze Casting
Nickel Bronze Castings  are on are used when  corrosion & high strength are  required. It's a material which is suitable for  hardware fittings such as window latches & hinges in all areas of construction including costal humid climate. Nickel bronze is also used in spark free fittings,sea water applications typical grade: C97600 or Z-CuNi20Sn4Zn5Pb4.

Aluminum Bronze 

Aluminum bronze alloys  have a very good corrosion  resistance. This material is  widely used in valves and pump  when it will come into contact  with salt water. It's used in many marine component and mining situations. Wearing strips are also made from this alloy when a strong hard wearing material is required.
Typical grade: AB1, AB2, or C95800, C95200 etc.

Leaded Gunmetal Casting
This is the most widely  used bronze. Has good  general properties which  cover most applications.  Because of it's widely use,  it's also the most cost effective bronze. Some uses of this material include hand wheels, valve body& components, pump cases & impellers and general engineering components when a bronze is required.
Typical Grade: LG1, LG2 or C83600 etc.
  
Manganese Bronze Casting

  Manganese Bronze is the  copper alloy mixed with a  certain proportion of the  manganese,theZinc,  aluminum and iron. This alloy  casting is with good resistance to wear, high intensity and plasticity. It's suitable for the propellers,large bearings for slow moving heavy loads as in mining equipment, marine components for its corrosion resistance.
Typical Grade: C86500 etc.
