Tantalum Bar Tantalum Rod for Chemical Equipment, Vacuum Furnaces and Electrodes | CHDY

Buyers of tantalum bar tantalum rod in the chemical equipment trade come to Shaanxi Chuanghui Daye Metal Material Co., Ltd. (CHDY). The same product also turns up inside vacuum furnaces. Electrodes are one more place. Unalloyed pure tantalum (Ta, atomic number 73) is what it starts from. Two grades are on offer: R05200 and R05400. Purity goes from 99.95% (3N5) up to 99.99% (4N). Oxygen is held under 150 ppm. Density: 16.69 g/cm³. Melting point sits near 3017 °C. A thin Ta2O5 film covers the surface, and it holds off hydrochloric, nitric and phosphoric acids below 150 °C. Your spec decides the diameter. Length and surface finish follow the same rule.

Material Characteristics of Tantalum Bars and Rods

Tantalum belongs to the refractory metals group. Density is high. On the surface you see a blue-gray metallic luster. This product is a semi-finished product. Drawing at room temperature works. Spinning works too. Machining is fine as well.

Left in air, the metal grows a thin Ta2O5 film by itself. Scratch that film and it builds back. Here is where the corrosion resistance comes from. Below 150 °C it stands up to hydrochloric, nitric and phosphoric acids. One question comes first when you pick a material: which acid does your process use? Concentration and operating temperature come next.

The linear expansion coefficient sits at 6.5×10⁻⁶/K. That high melting point is the reason the metal suits certain vacuum and high-temperature equipment.

Grades and Production Processes

R05200 is unalloyed tantalum. Vacuum arc melting is how it gets made. Powder metallurgy is the route for R05400. That grade is unalloyed tantalum too. General rod supply falls under ASTM B365. Medical use follows ASTM F560. Send us an inquiry and tell us which standard your project needs.

Quality Checks to Request

Buyers commonly specify the checks below. Confirm with CHDY which items apply to your grade and diameter.

Purity analysis (GDMS/ICP): Purity comes out between 99.95% (3N5) and 99.99% (4N). Oxygen is held under 150 ppm. Carbon and oxygen are interstitial elements. Each of them makes the metal more brittle.
Grain size inspection (ASTM E112): Machining gets easier when the grains recrystallize evenly. Coarse grains, on the other hand, can lead to tearing.
Non-destructive testing: Internal voids in rods with a larger diameter show up under ultrasonic testing (UT). Surface laps, seams or cracks become visible with penetrant testing (PT).
Mechanical testing: The tensile strength figure shown is over 200 MPa. Elongation results help confirm formability as well.

Every tantalum bar and tantalum rod order needs your checks listed in the purchase specification.

Industrial Applications

CHDY products serve metallurgy, electronics, medical and special steel fields. Tantalum bar tantalum rod is a starting material for:

Chemical equipment components: Used in hot acid service under 150 °C.
Electrodes: Rod stock gets machined into these, at the size you need.
Vacuum furnace parts: Vacuum and high-temperature equipment need a high melting point. This is why it fits.
Industrial fasteners: It is ductile. That makes forming and machining easy.
Research equipment: Its chemical and physical properties hold steady. They do not change.
Custom-machined components: Uniform grains support clean cutting.
Medical components: The material meets ASTM F560 where stated. Compare that with your own qualification requirements. That way you can confirm it fits.

Material Selection Before You Order

Work out one thing first: pure tantalum, or an alloy? Then check the grade against your application. Chemical composition counts as well. So do dimensions, and the surface condition too.

Tell us what you need and ask for a tantalum bar or tantalum rod quote. CHDY checks which material options are on hand, then comes back with choices that fit.

Storage Guidance for tantalum bar tantalum rod

Heat and moisture can hurt the protective oxide layer. So can abrasive contact. Store the material well and that surface stays sound until machining begins.

Keep the room between 20 °C and 25 °C (68 °F to 77 °F) for the rods. Relative humidity should stay under 50%. An HVAC system in a climate-controlled space takes care of this. Other industrial chemicals may sit nearby, so add exhaust fans or vents to keep the air clean. Choose a well-lit spot for routine inspection. Direct sunlight should not reach the rods. We also supply the tantalum bar tantalum rod in custom sizes to suit your drawing.

FAQ

Q: What is a tantalum rod?

A: This is a semi-finished product made of refractory metal. Pure tantalum (Ta, atomic number 73) gets turned into it by vacuum arc melting or by powder metallurgy. The acids listed above do not corrode it. You can form and machine it at room temperature without trouble.

Q: What are the main properties of tantalum rod?

A: Density reads 16.69 g/cm³. Around 3017 °C is where the melting point sits. Below 150 °C, the Ta2O5 film holds up against hydrochloric acid. Nitric acid and phosphoric acid do not affect it either.

Q: Which quality checks should I request?

A: Typical requests are purity analysis (GDMS/ICP), grain size inspection (ASTM E112), UT and PT testing, and mechanical testing. Tensile strength is listed as above 200 MPa.

Q: How should I store tantalum rods?

A: Store them between 20 °C and 25 °C. Keep humidity under 50%. Make sure air can flow around them. Do not put abrasive items nearby. Check them often under good light.

Q: Which grades are available?

A: R05200 is unalloyed. Vacuum arc melting makes it. R05400 is unalloyed too. Powder metallurgy is used for that one. Purity goes from 99.95% (3N5) to 99.99% (4N).

Q: Which details should I look at before I order?

A: Let us know if you want pure tantalum or an alloy. Send the grade and the chemical composition. The dimensions and surface condition should go in too. You can email those details to info@chdymetal.com. CHDY will review the choices and put together a quotation.
