Their raw materials conform the Standard Specification ASTM B 364 -96 for Tantalum and Tantalum Alloy Ingots
This specification covers unalloyed and alloyed tantalum ingots prepared by vacuum-arc melting, electron-beam melting, or powder-metallurgy consolidation to produce consolidated metal for processing to various mill shapes.
The materials covered by this specification are :
1. ASTM B 364 -96 UNS R05200, unalloyed tantalum, electron-beam furnace or vacuum-arc melt, or both.
2. ASTM B 364 -96 UNS R05400, unalloyed tantalum, powder-metallurgy consolidation.
3. ASTM B 364 -96 UNS R05255, tantalum alloy, 90% tantalum 10% tungsten, electron-beam furnace or vacuum-arc melt, or both.
4. ASTM B 364 -96 UNS R05252, tantalum alloy, 97.5% tantalum 2.5% tungsten, electron-beam furnace or vacuum-arc melt, or both.
5. ASTM B 364 -96 UNS R05240, tantalum alloy, 60% tantalum 40% columbium, electron-beam furnace or vacuum-arc melt, or both.
The ingot metal for Type R05200 (unalloyed tantalum), for Type R05255 (90% tantalum 10% tungsten alloy), Type R05252 (97.5% tantalum 2.5% tungsten alloy), and Type R05240 (60% tantalum 40% columbium) may be vacuum-arc melted, electron-beam furnace melted, or a combination of these two methods. The metal for Type R05400 is defined as powder-metallurgy consolidation unalloyed tantalum. |
