The Classification of Tantalum Wire
Tantalum wire can be classified according to its chemical purity, performance, use, and status.
According to its purity, tantalum wire can be divided into 3 categories: metallurgical tantalum wire, purity 99.0% Ta; high purity tantalum wire, purity 99.0% -99.9% Ta; ultra-high purity tantalum wire, purity 99.9% -99.99% Ta.
According to performance, tantalum wire can be divided into 4 categories: chemical corrosion-resistant tantalum wire; high temperature resistant high-strength tantalum wire; oxygen-resistant brittle tantalum wire; capacitor tantalum wire.
The tantalum wire of the capacitor is divided into 3 categories according to its uses: tantalum wire for the lead of solid tantalum electrolytic capacitors; tantalum wire for liquid tantalum electrolytic capacitor leads; tantalum wire for capacitors with reliability indicators.
According to the status, the capacitor tantalum wire can be divided into three categories: soft state, tensile strength σb = 300 ~ 600MPa; semi-hard state, tensile strength σb = 600 ~ 1000MPa; hard state, tensile strength σb> 1000MPa.
Tantalum Wire Packaging
Tantalum Wire is tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage or transportation.
