Tantalum plate is made by forging and rolling a billet of tantalum metal, a metal that is very heavy, ductile, hard, and highly resistant to corrosion. Tantalum plates are particularly resistant to chemicals at temperatures below 150 °C and can only be dissolved with hydrofluoric acid. Tantalum plates have a high melting point that creates an extremely thin protective oxide layer for high-quality capacitors, making it an excellent bulk material.

Edgetech is a leading global supplier of tantalum products with more than two decades of experience in the manufacturing and sales of tantalum products, providing customers with high-quality tantalum plates at very competitive prices.

The unique properties of tantalum plates

Corrosion Resistance: Tantalum plates can withstand exposure to a wide range of chemicals without corroding. This makes them ideal for chemical processing environments.

High Melting Point: They have one of the highest melting points among metals, ensuring performance in extremely hot conditions.

Excellent electrical conductivity: Their electrical conductivity makes them suitable for electronic applications, especially where heat resistance is critical.

Strength-to-weight ratio and durability: Tantalum has a density of approximately 16.4 grams per cubic centimeter, which contributes to its strength and durability. Tantalum plates have a high strength-to-weight ratio, making them strong and durable without being overly heavy. It is durable even in demanding applications. This advantage ensures long-term performance and reliability.

Tantalum’s unique properties make it invaluable across many industries.

Tantalum plate application

For laboratory equipment.

-Used as a replacement for platinum.

-Used in the manufacture of high temperature alloys and electron beam melting.

-Used in metallurgy, machining, glass and ceramic industries.

-Used as high temperature alloy additive in nickel-based alloys.

-For sputtering targets.

– For artificial ears.

-For making glass or metal seals.

Our tantalum tungsten (Ta-2.5%W) plate is designed for use in corrosive environments, while our tantalum tungsten alloy (Ta-10%W) is designed for high temperature corrosive environments. We also offer furnace grade tantalum, which contains small amounts of additives to slow grain growth and extend the life of your vacuum furnace.

Packing information for our Tantalum Plate

Our tantalum plates are mostly packed in wooden crates, this can protect the tantalum plate during transportation and handling. Carton is used for small pieces of tantalum plates.
