Sand Casting for Bronze & Aluminum Alloy

We have gained abundant experience in processes such as sand casting, investment casting, forging, welding stamping on material covering iron, stainless steel, carbon steel, steel alloy, aluminum ,alloy steel.3D Model Engineering Analysis, CNC Lathe Tooling and Machining. We have many years’experience in the supply of steel parts and forgings for automotive industry, investment and sand casting for energy industry and water works pipeline

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.
