Precision customization: Diameter 0.1–5.0 mm (typ. tolerance ±0.05 mm), annealed / cold drawn, multiple surface finishes; small-batch sampling supported.
Corrosion & biocompatibility: Excellent stability in hydrochloric, nitric acids and aqua regia, plus biocompatibility for medical use (final device approval by buyer).
High-temperature performance: High melting point and good strength retention for cyclic thermal loads.
Controlled purity: Strict tensile and chemical testing with low impurity levels for reliable performance in harsh and high-purity environments.
Electronics: Capacitor anodic leads, rectifier components, fine conductors.
Medical: Surgical sutures, markers and components requiring biocompatibility.
Chemical processing: Corrosion-resistant wire components for aggressive media.
Tensile testing
Chemical composition verification
Surface inspection (smoothness, defects)
Metallographic examination (microstructure uniformity)
Recrystallization temperature: approx. 900–1450°C
Use vacuum or dry inert gas atmospheres
All lubricants must be thoroughly removed prior to heat treatment to avoid embrittlement
