High purity: ≥99.95% tungsten for high-temperature strength and low thermal expansion.
Precision customization: diameter 0.02–2.0 mm; tolerance grades 0 / I / II; small-batch sampling.
Process control & QA: powder metallurgy with chemical/mechanical/surface/metallography checks; low impurities (single ≤0.01%, total ≤0.05%).
Stable conductivity: supports long life under cyclic heating for lighting and furnace elements.
Lighting: incandescent/halogen lamp filaments.
Electronics: gas-discharge electrodes for display devices.
High-temperature furnaces: heating elements for stable, uniform heat.
Chemical composition (purity/impurity control)
Mechanical properties (tensile strength, ductility)
Surface inspection (smoothness, defect-free)
Metallography (microstructure uniformity)
