Main Features

Pure nickel shows excellent corrosion resistance in alkaline solutions such as caustic soda, and also shows outstanding resistance against highly pure halogen gas and non-oxidizing acids. It is used in wide areas such as caustic soda concentration containers. The main features of the various types of pure nickel are indicated below.

Types and features of pure nickel handled by MMC Superalloy Corporations

NC-Ni(Ni200)	Normal pure nickel for industrial use.
LC-Ni(Ni201)	Low-carbon nickel. For its high thermal stability (315°C or above), it is used for equipments used in temperatures 315°C or higher.
D-Ni	Precipitation hardening type alloy material made by adding small amounts of aluminum and titanium. It is used for parts that require a high level of strength such as bolts and springs.
A-Ni	High-purity nickel. Purity is 99.7% or higher. Mainly used as electrode material.
K-Ni	High-purity nickel. Purity is 99.5% or higher. Mainly used as electrode material.

For plates and bars, the applied mechanical property standard may differ according to the finishing, heat treatment and size. Please contact our branch offices or service offices for details.

Weldability

Pure nickel can be welded easily by either MIG or TIG , however, when it is welded in high temperature it is necessary to completely remove slug to prevent high temperature corrosion. Nickel Filler Metal 61 is suited as the welding rod.
Please contact us regarding pure nickel welded pipes and chemical engineering machines that are also manufactured by MMC Superalloy .

Available Product Forms

Various shapes, such as flat-rolled plates, forgings, welding wire, wire, welded pipes and tubes, seamless pipes and tubes can be manufactured.
