Purchase and acceptance of tantalum raw materials. After the purchase of tantalum raw materials, the tantalum raw materials shall be checked and accepted and put into storage in a timely manner. The operation department shall be responsible for the registration of the tantalum raw materials number, the handling of warehousing procedures, and the collection and management of trace materials, transport documents and customs declaration documents of the mineral source supply chain.
The quality and technology department conducts acceptance inspection on tantalum raw materials, and the analysis room issues acceptance report. Raw material adoption.
Production and use departments receive tantalum raw materials from the warehouse according to the acceptance status, and the warehouse shall issue the tantalum raw material requisition form and make good records and registration. The management system shall be implemented as of the date of publication.
Tantalum is largely untouched by erosion. In surgery, tantalum contributes significantly to the repair of the human body. In foil or silk threads, broken nerves can be connected; Metal tantalum is a light gray metal with a slightly blue color. Due to its many strange characteristics, it has a wide range of applications, so it is called "metal kingdom".
Tantalum is very strong and can be up to -6. 5. It has a melting point of 2,996 degrees Celsius, third only to tungsten and rhenium. Tantalum is very malleable and can be pulled into wire or made into thin foil.
Its coefficient of thermal expansion is small, increasing by only 6.6 parts per million per degree Celsius. On top of that, it's incredibly tough, better than copper.
In the chemical, electronic, electrical and other industries, tantalum can replace the tasks that used to be carried out by the precious metal platinum, greatly reducing the cost required. In addition, tantalum is also an important element in steel making, corrosion resistant steel and heat resistant steel alloys, and can be used as special materials necessary for the development of space technologies such as rockets, spacecraft and jet planes.
