A Brief History of Ti Grade 1 Titanium

Ti Grade 1, also known as CP Titanium Grade 1, 3.7025 or UNS R50250, is a commercial pure titanium material.

Within the commercial pure titanium family, Ti Grade 1 is the grade with the lowest strength and the best ductility. It is not an alloyed titanium, nor is it a grade designed for high-strength load-bearing applications.

As titanium materials have gradually found their way into chemical, marine, industrial and medical applications, the market has required not only high-strength titanium alloys, but also a pure titanium material that is easier to form and weld, and offers stable corrosion resistance. The primary aim of Ti Grade 1 is to provide superior ductility and machinability within the commercial pure titanium system.

How was the Ti Grade 1 developed

The development of Ti Grade 1 stemmed from a practical need within the classification of commercial pure titanium grades: titanium materials must not only pursue higher strength but also retain superior ductility and formability.

The properties of commercial pure titanium are primarily influenced by the content of elements such as oxygen, iron, nitrogen, carbon and hydrogen, with oxygen content having a particularly significant impact on both strength and ductility. As oxygen content increases, strength typically rises, but ductility and formability decrease; impurity elements such as iron must also be kept within standard limits.

As capabilities in titanium refining and smelting control have improved, engineers are able to regulate these element contents more consistently. Commercially pure titanium is therefore classified into different grades to meet varying strength and processing requirements.

Grades 2, 3 and 4 offer higher strength and are suitable for components with more stringent strength requirements. However, in thin-sheet forming, deep drawing, bending, stretch forming and welding processes, excessive strength is not necessarily an advantage. If the material is too hard, it may actually increase the risk of cracking, springback and processing difficulties.

Ti Grade 1 is a low-strength, high-ductility grade of pure titanium developed to meet these requirements. Through the controlled use of lower levels of interstitial elements, it retains superior ductility, cold working properties and weldability, making the material more suitable for complex forming and thin-walled applications.

Early Applications of Ti Grade 1

Ti Grade 1 was initially used primarily for industrial components requiring corrosion resistance and good formability.

Common early applications included thin sheets for chemical processing equipment, heat exchanger components, corrosion-resistant liners, parts for electrolysis equipment, anode baskets, marine components and thin-walled welded structures.

These applications typically do not require high strength, but demand that the material remains stable in corrosive environments and can be bent, stamped, deep-drawn or welded.

Current Applications of Ti Grade 1

Ti Grade 1 is currently primarily used for titanium components requiring corrosion resistance, good ductility, cold workability and weldability.

Common applications include:

Medical applications: craniofacial repair plates, medical mesh plates, thin-sheet implants, dental membrane support components, medical device housings, and other medical titanium components with high formability requirements. Implant-related projects must be verified in accordance with ASTM F67, ISO 5832-2, drawing specifications, inspection documentation and the intended end use.

Aerospace applications: lightweight sheets, heat exchanger sheets, piping components, low-strength corrosion-resistant structural components and thin-walled titanium parts. Ti Grade 1 is not typically used as a high-strength load-bearing titanium alloy.

Industrial and chemical applications: Chemical heat exchangers, anode baskets, corrosion-resistant liners, electrolysis equipment components, marine environment components, corrosion-resistant vessel components and welded structural parts.

Mechanical engineering applications: Lightweight enclosures, corrosion-resistant protective plates, thin-walled structural components, sensor protective covers, formed parts and precision titanium components requiring good surface stability.

FAQs

Product FAQs

What types of components is Ti Grade 1 suitable for?

Ti Grade 1 is suitable for thin-gauge sheets, bent parts, stamped parts, deep-drawn parts, thin-walled structural components, and titanium parts requiring corrosion resistance and good formability.

Is the strength of Ti Grade 1 sufficient?

Ti Grade 1 is one of the lower-strength grades of commercial pure titanium. It is well-suited for parts where the primary requirements are corrosion resistance, light weight and ease of forming. If a part requires high load-bearing capacity or high strength, the choice of material should be reassessed.

Why is Ti Grade 1 suitable for forming processes?

Ti Grade 1 has a low oxygen content and good ductility and malleability, making it easier to cold work, bend, stamp and deep draw than other grades of commercial pure titanium.

How should one choose between Ti Grade 1 and Ti Grade 2?

Ti Grade 1 offers better ductility and formability, but has lower strength than Ti Grade 2. Ti Grade 2 has higher strength and a broader range of applications. The choice depends primarily on whether the part prioritises formability or strength.

Is Ti Grade 1 suitable for thin-sheet parts?

Yes. Ti Grade 1 is well-suited to thin sheets, thin-walled components and complex formed parts, and is particularly suitable for parts requiring bending, stamping and deep drawing.

Is Ti Grade 1 prone to deformation or scratching?

Yes. Ti Grade 1 has lower strength and hardness, making it a softer material. Care must be taken to protect the surface during machining, transport and clamping to avoid indentations, scratches and deformation.

Does Ti Grade 1 offer good corrosion resistance?

Yes. Ti Grade 1 offers good corrosion resistance and is suitable for many marine, chemical, medical and general industrial environments where corrosion resistance is required.

Specific suitability must still be confirmed based on the medium, temperature and operating conditions.

Is Ti Grade 1 suitable for welding?

Yes. Ti Grade 1 has good weldability, but gas shielding must be used during welding to prevent the weld area from being contaminated by oxygen, nitrogen or hydrogen, as this would otherwise affect the quality of the weld and the material’s properties.

Is Ti Grade 1 easy to machine?

Ti Grade 1 can be machined, but as titanium has low thermal conductivity, it is prone to heat build-up during cutting and tool sticking.

Appropriate cutting tools, machining parameters and cooling methods are required during machining.

Can the strength of Ti Grade 1 be improved through heat treatment?

No. Ti Grade 1 is commercial pure titanium and cannot be significantly strengthened through heat treatment. Its strength depends primarily on the material condition and cold working methods.

Is Ti Grade 1 suitable for medical applications?

Ti Grade 1 can be used in certain medical devices and implant-related applications; however, whether it is suitable for a specific medical product must be confirmed in accordance with ISO 5832-2, ASTM F67, drawings and regulatory requirements.

What key points should be confirmed when purchasing Ti Grade 1?

When purchasing Ti Grade 1, key points to confirm include material standards, product form, dimensions, tolerances, surface finish, delivery condition, quantity and end use. For thin sheet components, formed parts or medical projects, surface quality and inspection documentation requirements should also be confirmed in advance.

What forms of Ti Grade 1 products can Sunxin supply?

Sunxin can supply Ti Grade 1 titanium sheets, bars, wire and tubes. Specific dimensions, tolerances, surface conditions and delivery conditions can be confirmed according to application requirements.
