View DetailsGrade 1 Titanium
The softest and most ductile commercially pure titanium grade, prioritized for maximum formability and corrosion resistance in demanding forming applications.
Product Overview
Bokang's Grade 1 Titanium is manufactured using advanced vacuum arc remelting technology, ensuring exceptional purity and consistent mechanical properties.
Grade 1 titanium is the purest and most ductile of the ASTM commercially pure (CP) titanium grades. It contains the lowest allowable levels of interstitial elements like oxygen, nitrogen, and iron, resulting in the lowest tensile strength but the highest elongation and formability among the titanium family. Its minimum titanium content is 99.5%.
This grade exhibits exceptional corrosion resistance, forming a tenacious, self-healing oxide layer in the presence of oxygen or moisture. Its primary advantage lies in its ability to undergo severe cold forming operations, such as deep drawing, spinning, and stretch forming, without intermediate annealing. While its mechanical strength is lower, it is often selected for applications where intricate shapes need to be formed from sheet or where corrosion resistance is paramount and load-bearing requirements are minimal. It is also known for excellent impact toughness at cryogenic temperatures.

Material Selection Guide
How to choose the right titanium wire for your application
1
Prioritize Forming Complexity
Select Grade 1 when the component design involves severe bending, deep drawing, or spinning where other grades might crack or require intermediate annealing.
2
Check Load-Bearing Requirements
Verify that the lower strength of Grade 1 (170 MPa min yield) is adequate for the structural or pressure requirements of the application. If not, consider Grade 2.
3
Consider Surface Treatment Plans
For applications requiring decorative or functional anodizing, Grade 1 provides a uniform base that yields consistent and high-quality oxide layer colors.
4
Assess Temperature of Service
For cryogenic applications down to -269°C, Grade 1 is an excellent choice due to its retention of toughness. For elevated temperatures, its low strength is a limiting factor.
Production Process & Quality Control
Our rigorous manufacturing process ensures consistent quality
High-Purity Sponge Selection
Titanium sponge with the lowest feasible oxygen and iron content is selected to meet Grade 1's stringent interstitial limits.
→
Consumable Electrode Assembly
The sponge is compacted into electrodes with minimal alloy additions, maintaining the high-purity target composition.
→
Single or Double VAR Melting
Electrodes are melted in a Vacuum Arc Remelting furnace to create a homogeneous ingot, with careful control to prevent contamination.
→
Hot Rolling to Intermediate Gauge
The ingot is hot-rolled into coil or sheet form at temperatures that avoid excessive oxygen pick-up.
→
Cold Rolling & Annealing
Material is cold-rolled to final thickness with intermediate vacuum anneals to recrystallize the grain structure and maintain softness.
→
Final Finishing & Slitting
Sheets are pickled, leveled, and slit to width. Surface inspection ensures freedom from defects critical for forming and anodizing.
Frequently Asked Questions
Common questions about pure titanium wire
Choose Grade 1 when the application demands the absolute maximum formability, such as for deep-drawn caps, complex expansion bellows, or intricate architectural features. Also select it when material purity is critical for subsequent anodizing or for cryogenic service where superior toughness is needed. If moderate strength is required alongside good formability, Grade 2 is often the more common and cost-effective choice.
Yes, Grade 1 titanium has excellent weldability, arguably the best among titanium grades due to its high purity. It is commonly welded using GTAW (TIG) with matching ERTi-1 filler wire. As with all titanium, successful welding requires meticulous cleaning and inert gas shielding to prevent contamination.
It can be used for pressure-containing applications, but its low yield strength limits the allowable design stresses according to codes like ASME Boiler and Pressure Vessel Code. This often results in thicker wall sections compared to higher-strength grades, which may offset cost benefits. Engineering review is essential.
Its high chemical purity and uniform microstructure lead to a consistent and smooth growth of the anodic oxide layer. This results in more uniform coloration (interference colors) with fewer streaks or spots compared to grades with higher alloy or interstitial content, which can cause localized variations in the oxide thickness and color.
Like most commercially pure titanium, Grade 1 has limited resistance to reducing acids like sulfuric and hydrochloric, especially in hot, concentrated, or unaerated conditions. It may corrode. For such environments, titanium alloys with palladium (e.g., Grade 7, 11) or nickel-molybdenum (e.g., Grade 12) additions are specifically designed.
