Tantalum and Niobium Cutting Tool Engineering

2021-1-6  Tantalum usage for cemented carbides is estimated at about 240 tons per annum. Niobium usage for cemented carbides is estimated at about 60 tons per annum. (Note that the above figures include reclaim, estimated at approximately 20%, and are for entire worldwide estimates, excluding the former Soviet Union.)

Machining Niobium Alloys How To Work With

Machining Niobium. All of the normal machining techniques can be used for Niobium. Niobium has a strong tendency to gall. Special attention needs to be paid to tool design and lubricant use. In lathe turning, the metal behaves similar to soft copper.

2020-1-8  preliminary study of characterization of tantalum ores from leucogranite and alluvial deposits is presented to be used as a base for design the milling experiments to optimize the tantalum recovering during the processing. In the ore deposits tantalum appears in solid solution with niobium in complex oxides, which forms low grade aggregates

Machining of Tantalum X-medics

Machining of tantalum is difficult. It has been described as “kind of like machining copper with the hardness of titanium” 1.Especially annealed tantalum may cause problems, being ‘sticky’, as well as having a strong tendency to seize, tear and gall 2.Unannealed tantalum material is in general more suitable for machining than annealed.

Machining Tantalum Alloys Welding Metal Tantalum

There are many uses of Tantalum metal and alloys. Below are details on machining Tantalum including welding, grinding, spinning and more! Turning and Milling. In lathe operations, cemented carbide tools with high cutting speeds should be used. The tools should be kept sharp and ground with as much positive rake as the tool can withstand.

2 天前  Tantalum parts for electronic tubes are often blasted with steel grit to provide greater radiation surface. The recommended procedure is a blast of a few seconds with No. 90 steel grit at a pressure of 20 to 40 psi followed by thorough cleaning in hot hydrochloric acid as already described. Sand, alumina, silicon carbide or other abrasives

Tantalum niobium carbide H.C. Starck

The tantalum, niobium and tantalum niobium carbides produced by H.C. Starck are characterized by a particularly narrow grain size distribution and an extremely low level of impurities. Usually, the (Ta,Nb)C mixed crystals used in practical applications have varying ratios of tantalum to niobium.
