Tantalum Plate

Tantalum Plate

tantalum-plate

Brief introduction:

Tantalum is one kind of metallic element. Tantalum has such properties as hard texture, high melting point and corrosion resistance. All of these properties make its application field wide. Half of tantalum production is used in the production of tantalum capacitors.

Tantalum plate is manufactured from tantalum powder by rolling. The difference between tantalum plate and tantalum sheet is that tantalum plate is thicker that tantalum sheet. While their manufacturing processes are same.

Properties of tantalum plate:

Tantalum plate has the same properties of tantalum.

The purity of tantalum plate is 99.95% or  99.99%. Tantalum plate is produced strictly accordance with ASTM B 708 98.

JINXING Co., Ltd can provide tantalum plate according to customers’ requirements. We also supply tantalum alloys products.
