Tantalum Sheet

Tantalum Sheet

tungsten-sheet

Brief introduction:

Tantalum source is one kind of metallic element. Tantalum sources of our country make up 14.22% of total world’s tantalum storage. On recent market, demand for tantalum keep weak stability and tantalum price remains stable.

Tantalum sheet is produced from tantalum powder by cold rolling or hot rolling processing. Purity of tantalum sheet is 99.95%or 99.99%. Standard of tantalum sheet is conform with ASTM B 708 98.

Properties of tantalum sheet:

Properties of tantalum sheet is same with those of tantalum, such as  hard texture and high corrosion resistance.

Classifications of tantalum sheet:

Tantalum sheet can be grouped into tantalum plate, tantalum strip and tantalum foil according to different sizes.

JINXING Co., Ltd can produce tantalum sheets according to customers’ requirements.
