Pure Tantalum Plate

Pure Tantalum Plate for Chemical, Semiconductor and Medical Equipment: R05200 and R05400 Grades

Chdymetal works out of Baoji, China. Flat products in unalloyed tantalum leave our plant for chemical plants. Semiconductor makers buy them as well. Medical firms order them too. Unalloyed tantalum is what goes into the Pure Tantalum Plate we make. You can pick from two grades, R05200 and R05400, and both follow ASTM B708. Thickness starts at 0.5 mm. The top end is 20 mm. Width runs from 50 mm to 1200 mm. Length goes from 30 mm to 2500 mm. Density is 16.69 g/cm³. Melting point sits at 2996 °C. Send us the grade, the size, and the working medium. We will then point you to a plate that suits your equipment.

What Is plate?

A tantalum plate counts as a flat mill product. Unalloyed tantalum (Ta) goes into it, and the result meets ASTM B708. Grade R05200 comes from vacuum arc melting. Electron-beam melting does the same job. For grade R05400, powder metallurgy is the route instead. Purity normally lands above 99.95% (3N5). Plenty of orders ask for more, up to 99.99% (4N). Name the purity you need when you request a quote. We also supply the Pure Tantalum Plate in custom sizes to suit your drawing.

Liners and heat exchanger plates in hot acid service are common jobs for this product. Hydrochloric, sulfuric and nitric acid all show up in these builds. How long a plate lasts depends on the temperature and on the acid concentration. Equipment design plays a part too.

Key Material Properties

Tantalum needs high heat before it melts. Bending gives no trouble either. Tensile strength usually lands between 205 and 300 MPa. Elongation holds above 20 to 30%. With figures like that, forming work such as deep drawing becomes possible.

A stable oxide film (Ta₂O₅) forms when tantalum meets oxygen. This layer is what keeps the metal from corroding. Capacitors rely on tantalum for the same film.

The typical oxygen limit of <150 ppm and carbon limit of <50 ppm for the high grade are relevant to embrittlement risk. A typical grain size of ASTM 6 or finer may help limit surface roughening ("orange peel") during forming.

Where Tantalum Plate Is Used

Chemical Process Equipment

Pure Tantalum Plate is used for bayonet heaters, shell-and-tube heat exchangers and reaction vessel cladding, where equipment is exposed to aggressive acids.

Semiconductor and Electronics

Plate serves as a precursor material for sputtering targets. These targets deposit diffusion barrier layers that limit copper migration into silicon. Tantalum is also used in capacitors.

Be used in a wide range of industries.

Medical Devices

In living tissue, the metal does not react. Cranial plates are one shape it takes. Suture clips are another. Porous meshes for bone rebuilds are a third. Medical jobs need documents that match your regulatory route. Before you order, ask what stock we hold.

R05200 or R05400: Choosing the Grade

These two grades are made in different ways. For R05200, vacuum arc melting is one method. Electron-beam melting is the other route for it. R05400 is produced by powder metallurgy. The forming method changes the choice. The working medium matters as well. Project needs matter too. Include these details in your inquiry. We check the grade first. Then we send the quote.

Quality Checks Before You Buy

Go through each of these against ASTM B708. Your own QC protocol applies too.

• Chemical composition (GDMS or ICP-OES): Purity gets checked here, along with the C, O, N and H levels. Hydrogen and gas embrittlement are driven by those levels.
• Grain size (ASTM E112): An even, equiaxed structure is the goal. Forming stays consistent with it.
• Ultrasonic testing (ASTM E214): Voids and internal delamination show up with this test. For parts headed into vacuum service, that matters.
• Dimensions: Will the plate be stamped or welded on an automated line? Then check flatness and how even the thickness is.

Tell us which test reports you need. We will let you know what we can supply.

Pure Tantalum Plate Ordering Checklist

Get these ready before you order this product:

• Grade (R05200 or R05400)
• Thickness, width and length
• Purity requirement
• Working medium
• Forming or welding method
• Required test reports

Handling and Fabrication Guidelines

Hot tantalum plate does not belong in air. Oxidation speeds up above 300 °C. Beyond 500 °C, the metal absorbs gas and turns brittle. High-temperature service calls for vacuum or inert gas.

A clean work area is a must for welding. TIG work should be done in a vacuum chamber or a glove box. It must keep 99.999% argon shielding inside.

Iron or zinc can form a galvanic couple with metals in the same system. Hydrogen may then enter the tantalum. Keep the tantalum electrically separate from those metals.

FAQ

Q: What sets R05200 apart from R05400?

A: Vacuum arc melting makes R05200. Electron beam melting does the same job. R05400 is different, it comes from powder metallurgy.

Q: Can tantalum plate be used in air at high temperatures?

A: No. Oxidation gets fast once you go above 300 °C. Past 500 °C the metal turns brittle. Vacuum or inert gas is what you need.

Q: How is tantalum plate welded?

A: Do the welding in a vacuum chamber or a glove box. There, TIG welding with 99.999% argon shielding works. Oxygen stays away from the weld pool that way.

Q: What makes the tantalum price move?

A: Feedstock availability drives most of it. Mine regulation and the compliance paperwork behind each shipment add to that. So does the cost of getting the metal to a usable purity. When concentrate is tight, quotes move within weeks.

Q: Can tantalum plate suffer from hydrogen embrittlement?

A: It can, though it takes the right conditions. Put the plate in an electrolyte next to iron or zinc and a galvanic couple forms. Atomic hydrogen then loads the metal through that couple. Keep the part electrically isolated wherever mixed metals sit together.

Q: What sizes can I order?

A: Thickness runs 0.5–20 mm. Width covers 50–1200 mm, and length goes up to 2500 mm, with a 30 mm floor.
