High purity: ≥99.95% tungsten for high-temp resistance and low thermal expansion.
Precision customization: OD 6–200 mm, ID 3–180 mm, length ≤1500 mm; small-batch sampling.
Process control & QA: powder metallurgy with chemical/mechanical/surface checks; low impurities (single ≤0.01%, total ≤0.05%).
Thermocouple protection: shields sensors in extreme heat.
Sapphire furnaces: structural components for crystal growth.
High-temp sintering: furnace elements sustaining thermal stress.
Chemical composition (purity/impurity control)
Mechanical properties (strength, hardness)
Surface inspection (smoothness, defect-free)
Packaging: pearl-cotton protection + export wooden cases; anti-collision packing.
Shipping: global courier or sea freight; lead times aligned with your schedule.
LuminaTitanium provides high-purity (≥99.95%) tungsten tubes produced via powder metallurgy. With excellent high-temperature strength and low thermal expansion, our tubes are configured to exact OD/ID/length for thermocouple protection, sapphire furnaces, and high-temp industrial equipment.
