Key Benefits

• Outstanding stability in reducing acid environments where Gr2 pure titanium wire suffers corrosion failure
• Palladium additive stabilizes passive film under low pH and chloride mixed corrosive conditions
• Good ductility for bending, forming and fabricating hangers, filter components and small fastener blanks
• Resists crevice corrosion in mixed acid and halogen ion service scenarios
• Consistent performance in continuous operation of wet metallurgy and fine chemical plants

Grade Description

Gr7 (Ti-0.15Pd) titanium palladium alloy wire is defined under ASTM B863. The palladium addition greatly improves corrosion resistance in reducing acid media. Different from Gr2 pure titanium wire only suitable for oxidizing chloride environment, Gr7 works reliably in harsher reducing corrosive conditions. Our Gr7 titanium wire is supplied to fine chemical and hydrometallurgy EPC projects in Portugal, Indonesia and Chile.

Product Features

Our cold drawn Gr7 titanium palladium wire is fully annealed and pickled to remove surface oxide scale. Every wire coil undergoes dimension inspection and precise chemical composition test to guarantee palladium content. Gr7 titanium wire is commonly manufactured into anti-corrosion hanging parts, filter mesh wire and small structural components for severe corrosive chemical reactors.

Industry Applications

• Fine chemical & hydrometallurgy: reducing acid equipment hangers, filter wire, corrosion resistant small parts
• Chloride containing wet metallurgy leaching system and corrosive solution handling facilities
• Chemical and mineral processing EPC projects in Portugal, Indonesia and Chile

Quality Assurance

Every batch undergoes strict inspection before shipment:

• Full dimension tolerance inspection
• Tensile & elongation mechanical property testing
• Precise chemical composition testing including palladium content
• Material Test Certificate (MTC) supplied for traceability

FAQ

Q: When should I select Gr7 titanium wire instead of Gr2?
A: Choose Gr7 Ti-0.15Pd wire if your working medium contains reducing acid with chloride ions. Gr2 pure titanium cannot maintain stable passivation under these harsh conditions.

Q: Can Gr7 titanium wire be cut into custom lengths?
A: Yes. Our engineering team can read customer drawings and cut Gr7 coil wire into custom straight segments for component fabrication.

Q: What specification governs Gr7 titanium wire?
A: Our Gr7 titanium wire fully complies with ASTM B863, accepted for international chemical and mining project bidding.
