We provide a variety of commonly used nickel-based metal casting alloys to meet customer needs for metal casting projects. When converting from previously designed forged parts to nickel-based castings, nickel-based metal castings can usually be designed to increase productivity and reduce the total cost of nickel-based alloy castings.

The choice of alloy is a very important aspect of part design. Choosing the right nickel-based alloy depends on several factors, including the environment in which the nickel-based casting is in use. In addition, if nickel-based alloy castings are used in combination with forged parts (that is, two parts are welded together), preliminary discussions must be conducted with metallurgical experts to ensure that you choose the appropriate chemical and material performance application that suits you. important.

Nickel-based alloys are known for their oxidation and corrosion resistance in harsh environments and high temperature applications. In addition, in today's market, ASTM specifications allow everyone to use multiple brand names for nickel-based alloys, including:

· Monel®-Monel® is a nickel-based alloy, mainly composed of nickel (up to 67%) and copper, with small amounts of iron, manganese, carbon and silicon. Monel® is stronger than pure nickel, and its alloy is resistant to many corrosive agents, including fast-flowing seawater. They can be easily cast and manufactured by hot working and cold working, post-casting processing and welding.

·Hastalloy®-Hastalloy® is a nickel-based metal casting alloy with high corrosion resistance. The inclusion of molybdenum makes Hastalloy® harder and stronger at high temperatures, making it ideal for welding applications. These nickel-based alloy castings are easy to manufacture and shape. They have good ductility and can be forged and cold worked.

·Inconel®-Inconel® nickel-based alloy castings are anti-oxidation and corrosion materials, which are very suitable for use in extreme environments that are often subjected to pressure and heat. After heating, Inconel® will form a thick and stable passivation oxide layer to protect the surface from further erosion. Inconel® can maintain strength over a wide temperature range and is attractive for high-temperature applications. In high-temperature applications, aluminum and steel will yield creep due to hot crystal vacancies. The high-temperature strength of this nickel-based alloy is developed through solid solution strengthening or precipitation hardening.
