Nickel 200/201

　　Nickel 200 is a commercially pure nickel alloy possessing good corrosion resistance and relatively low electrical resistivity. Has been used in a wide variety of applications including food handling equipment, magnetically actuated parts, sonar devices, and electrical and electronic leads.

　　Nickel 201 is a low carbon variety of Nickel alloy 200 possessing low annealed hardness and a very low work-hardening rate desirable for cold forming operations. It is highly resistant to corrosion by neutral and alkaline salt solutions, fluorine and chlorine. Has been used in food and synthetic fiber processing, heat exchangers, chemical and electrical industries.

Tantalum Product 

---

Tantalum

　　It is a greyish silver, heavy, and very hard metal. When pure, it is ductile and can be drawn into fine wire, which can be used as a filament for evaporating metals such as aluminium. Tantalum is almost completely immune to chemical attack at temperatures below 150°C, and is attacked only by hydrofluoric acid, acidic solutions containing the fluoride ion, and free sulphur trioxide. The element has a melting point exceeded only by tungsten and rhenium. 

　　The major use for tantalum is in the production of electronic components, mainly tantalum capacitors, which are very small relative to their capacity.
