Cast Iron

WKPT is a company that can provide a variety of high-quality, full-scale cast iron products, including gray cast iron, ductile iron, high-silicon-molybdenum ductile iron, Austempered Ductile Iron (ADI), and other special customized materials. ADI has a higher elongation rate and is dominant under the same tensile strength as other materials, so it is commonly used in many industrial parts, such as turbine housing, cylinder chambers, exhaust manifolds, chassis, and cantilever brackets, etc. in transportation, agricultural machinery, and construction machinery. The global demand for ADI has grown substantially. At present, the annual output is 180,000 tons in Taiwan and it might replace malleable cast iron and forged steel potentially in the future.

In addition to ADI, WKPT has also developed other types of high-quality cast iron materials such as low-temperature impact-resistant ductile iron. This material has a better impact resistance at low temperatures, which makes it ideal for mechanical parts in low-temperature environments. At present, We have developed -20°C low-temperature impact-resistant cast iron and kept researching –40~-60°C cast iron continuously. In addition, WKPT has been researching and developing cast iron with high ferrite structure and high spheroidization rate, which will be used in various mechanical parts. As stated above, WKPT is a trustworthy supplier of cast iron products that is capable of providing customers with a variety of high-quality, full-spec cast iron products to meet the demands of customers.
