规格
钽和钽合金的规格由ASTM制定，具体如下：ASTM B365 – 98(2004) Standard Specification for Tantalum and Tantalum Alloys – Rod and Wire
ASTM B521 – 98(2004) Standard Specification for Tantalum and Tantalum Alloys – Seamless and Welded Tubes
ASTM B708 – 05 Standard Specification for Tantalum and Tantalum Alloys – Plate, Sheet and Strip
In addition, specifications are also provided for Tantalum in the materials datasheets of the VdTUEV.
VdTUEV 382 – 9.96 Unalloyed Tantalum
VdTUEV 507 – 9.96 Tantalum 2.5% Tungsten
在今天的化学和制药行业，含有2.5%的钨合金使用最为广泛，因为它在20℃时实现接近240 Mpa的允许抗拉强度。对于这种合金材料的规格由ATSM规定，在R05252等级下和材料数据表VdTUEV 507中
