Products Description
Tantalum wire is a kind of filamentous tantalum material made from tantalum powder by plastic processing methods such as rolling and drawing. Tantalum has the characteristics of high melting point, low vapor pressure, good cold workability, high chemical stability and strong corrosion resistance of a liquid metal. It is widely used in many fields, especially in electronics industry.

Tantalum wire is widely used in the electronic industry, and is used primarily as anode lead of tantalum electrolytic capacitor. Tantalum electrolytic capacitor is a kind of capacitor with excellent performance, and its anode is usually made of tantalum wire. Tantalum wire is an ideal material for making anode lead of this capacitor because of its high melting point, good conductivity and chemical stability. In addition, tantalum wire can also form a stable oxide film in the working process of a capacitor, which improves the performance and service life of the capacitor.

Capacitor-grade tantalum wire can be divided into many varieties according to different states and specifications, and the smallest diameter tantalum wire can reach φ 0.10 mm.. These tantalum wires undergo strict processing and quality control to ensure that they meet the high requirements of capacitor manufacturing. For example, the technical indexes of tantalum wire of liquid tantalum capacitors are the same as those of tantalum wire of solid tantalum capacitors except for high surface quality.

Tantalum wire is the key material for making tantalum capacitors. Tantalum capacitors are widely used in communication, computers, automobiles, household and office appliances, instruments and meters, aerospace, national defense and military industries and other industrial and scientific departments because of their excellent performance. Tantalum capacitors have comprehensive properties such as high capacitance, low leakage current, low equivalent series resistance, good high and low-temperature characteristics, long service life, etc. These performance advantages are largely due to the application of tantalum wires.
