Tantalum rod +Tantalum alloy rod

Detailed Product Description

Baoji Zhong Bang rare metal materials CO.,LTD holds Tantalum ,Niobium as the dominant products in the scope of rare metal new materials, including many sorts and grades of their metals, sheet, tube, wire ,rod ,crucible , target ,alloy and so on.

Tantalum features high melting point , low vapor pressure , good cold processability ,excellent chemical stability , good resistance to corrosion , high dielectric constant ,in surface oxide film .widely used in many industries such as electronics ,metallurgy, chemical processing , hard alloy cutters , aerospace and aviation.

 

We can produce all kinds of tantalum alloy rods,such as Ta2.5W,Ta10W,Ta40Nb,

size: 3.0mm up to 120mm Diameter x random length, They are very popular in the market on account of their superior quality and competitive price.Special requirements to be agreed on by the supplier and buyer of negotiation.
