Principal Design Features
|
|
Also called KBI-6, Tungsten is added for increased strength.
|

|
Applications
|
|
Applications for tantalum fall into two major categories: electronic and metallurgical. The electronics industry is the largest single user, where it is employed in capacitors, filaments and various other high temperature components. The chemical process equipment industry commonly employs tantalum in heat exchangers, heaters, vessels, etc.

|
|
Machinability
|
|
Tantalum has a tendency to gall, very similar to pure copper. This can cause welding of tooling to the workpiece if proper procedures are not followed. Heavy roughing cuts with M2 high speed or C2 carbide tooling is recommended. To minimize galling, high speed tooling with generous lubricant flooding is recommended. Speeds of 40-60 fpm are recommended.

|
|
Forming
|
|
With fully annealed material, spinning, deep drawing, blanking and punching can easily be performed. The material has a relatively low work hardening rate.
|
|
|
Welding
|
|
Tantalum can be fusion and resistance welded successfully. Resistance welding should be performed under water. Fusion welding is most successful when the material to be joined is absolutely clean.
|
|
|
Forging
|
|
Forge at 2200 down to 1500 F.
|
|
|
Annealing
|
|
Recrystalization occurs in tantalum between 2000 and 2500 F. A high vacuum furnace is strongly recommended.
|
|
|
Hardening
|
|
Tantalum can only he hardened through cold work.
