Cast Nickel Alloy ASTM A494 Grade CZ100: Material Technical Passport
Engineering Handbook: Cast Nickel Alloy ASTM A494 Grade CZ100
Nickel alloy grade CZ100 is a cast material designed for operation in highly aggressive environments. Its key feature is exceptional resistance to concentrated alkalis, which makes it indispensable in specific industrial sectors. EV Group China process engineers classify this material as the cast equivalent of technically pure wrought nickel (Nickel 200). CZ100 alloy is in demand in the chemical and petroleum refining sectors for manufacturing components that operate under conditions of caustic corrosion and where the preservation of magnetic properties and product purity is required.

Normalized Chemical Composition of Grade CZ100 Alloy (%)
The balanced chemical composition, regulated by the ASTM A494 standard, determines the high chemical passivity of CZ100 alloy in reducing environments. Controlling the content of impurities, such as sulfur and phosphorus, is critically important for ensuring the corrosion resistance and mechanical properties of castings. Below are the limiting values for element concentrations.

Key Physical Parameters
The density of nickel alloy A494 Gr CZ100 (specific gravity) is 5.68 g/cm³. This indicator is fundamental for performing accurate engineering calculations of the mass of finished products and determining loads on load-bearing structures and foundation bases when designing industrial installations.
Processability and Weldability of Cast CZ100 Alloy
CZ100 alloy has satisfactory weldability with strict adherence to technological procedures. To obtain a high-quality welded joint, careful preparation of the casting surface is required, and in some cases, preheating. Welding work must be performed using recommended filler materials compatible with the base metal.
