Tantalum Bar

Tantalum Bar

tantalum-bar

Brief introduction:

Tantalum bar belongs to tantalum product. The processing technology of tantalum bar is is similar to that of tantalum rod. Tantalum bar is produced from tantalum powder by sintering, forging, drawing and polishing.

Material: RO5200, RO5400, RO5252(Ta-2.5W), RO5255(Ta-10W)
Available size:¢4~¢120mm
Standard: As per ASTM B 365-98

Properties of tantalum bar:

Properties of tantalum bar is same as that of tantalum rod, such as good strength and hardness, low density, light weight, high temperature resistance, low temperature resistance, good mechanical properties, excellent corrosion resistance and good heat transfer performance.

Applications of tantalum bar:

Titanium bars are popularly used in navigation, aerospace, vacuum salt making, automobile industry, medical and sports, papermaking, textile industry, electric power industry, metallurgical industry, fertilizer industry, seawater desalination industry. Tantalum bar is also used to produce watch shell, computer shell and spare parts.

JINXING Co., Ltd can manufacture tantalum bars according to buyers’ requirements.
