Titanium Angle

Titanium angle steel, also known as titanium L-shaped profiles or titanium angle aluminum, is a structural profile with a 90-degree angle. It is widely used in load-bearing structures, connecting brackets, reinforcing frames, and various corrosion-resistant applications. Compared to aluminum or stainless steel, titanium offers a higher strength-to-weight ratio and superior corrosion resistance, making it suitable for extreme working environments, offering a longer lifespan, and a more cost-effective solution.

Popular grades of titanium angle

Titanium angle steel is a structural profile widely used for support, connection, reinforcement and other purposes. Different grades of titanium have differences in strength, corrosion resistance and weldability, which makes them have their own advantages in different structural scenarios. The following are several commonly used and popular titanium angle steel materials:

• 

  Gr2 Titanium Angle Moderate strength, excellent corrosion resistance, and good weldability. Suitable for structures with high corrosion resistance requirements but medium loads, such as offshore platform supports, chemical plant support structures, and medical clean room frames.

• 

  Gr5 Titanium Angle High strength and lightweight, suitable for load-bearing structures. Widely used in aviation equipment brackets, racing car frames, bicycle structural connectors and other parts with high requirements for both weight and strength.

• 

  Gr7 Titanium Angle Steel Based on Gr2, it has enhanced corrosion resistance in chlorine-containing environments. It is suitable for chlorine treatment equipment support frames, seawater desalination device frames, and coastal structure anti-corrosion reinforcement support parts.

• 

  Gr12 Titanium Angle It has both corrosion resistance and medium strength, and is particularly suitable for use in environments where thermal stress and corrosion coexist, such as heat exchanger pipe racks, steam system supports, and heat exchange station structural components.

Chalco also offers custom L-profiles in titanium alloys such as Gr9 and Gr23 for special load, temperature, or corrosion resistance requirements. Contact us for recommendations and samples. Get a quick quote .

What are the advantages of titanium angle steel?

Excellent corrosion resistance

Gr2 and Gr7 titanium angle steels can last for more than 10 years in seawater, chloride, high humidity, acid and alkali environments without replacement; compared to 304/316 stainless steel, the corrosion rate is one order of magnitude lower and is almost maintenance-free.

High strength to weight ratio, suitable for replacing steel structures to reduce weight

Gr5 titanium angle steel boasts approximately twice the strength of Q235 carbon steel, yet only 56% of its density. While maintaining the same load requirements, it can reduce structural weight by 40% to 50%. It is widely used in high-strength, lightweight applications such as aviation brackets and racing frames.

Weldable and machinable, easy to connect with other structures

Titanium angle steel can be structurally spliced using TIG welding and titanium-specific welding wire (such as ERTi-2/ERTi-5). Conventional sawing, water jet cutting, and CNC processing are also applicable, facilitating later assembly and customization.

Non-magnetic

The non-magnetic properties make titanium angle steel the first choice for frame supports of MRI medical equipment and radar electronic equipment. Replacing carbon steel can eliminate the risk of magnetic interference.

Low thermal expansion coefficient and more stable structure

The thermal expansion coefficient of titanium is approximately 60% of that of stainless steel. It can maintain better dimensional and connection stability in environments with drastic temperature changes (such as outdoors and steam system brackets), reducing deformation due to thermal expansion and contraction.

Strong fatigue resistance

The fatigue strength of titanium is higher than that of aluminum alloy and stainless steel, and it is particularly suitable for vibration and cyclic load conditions, such as ships, mechanical equipment frames, bridge nodes and other long-term operating structures.

Which process is right for your titanium angle steel project?

Titanium angles can be formed using a variety of manufacturing processes, each suited to different dimensional, tolerance, production volume, and budget requirements. Chalco Titanium offers a variety of production paths to help you balance performance, cost, and delivery schedules.

Die extrusion molding

Titanium ingots are extruded through specialized dies at high temperatures to form continuous, uniformly shaped L-shaped profiles. This process is highly efficient and produces sharp edges and corners. Subsequent straightening, cutting, and heat treatment ensure strong dimensional stability.

Selection suggestion: If you need large quantities of equal or unequal-sided titanium angle steel with consistent side length and good surface consistency, we recommend extrusion molding, which is suitable for standardized applications such as aviation, medical, and mechanical frames.

Hot rolling/hot bending

This process is performed by pressing or bending the heated titanium blank into a desired shape. It is suitable for structural parts with thicker sections or non-standard angles. This process is highly flexible and suitable for small batches and custom projects, but its surface and angle accuracy is slightly lower than that of extrusion.

Selection suggestion: If your project involves thick-walled structures, non-90° angles, or does not require high appearance consistency, hot rolling or hot bending processes can be used, which are more cost-effective and suitable for scenarios such as engineering brackets and heat exchange equipment structures.

Custom mold making

Titanium angles with special cross-sections, compound angles, holes, or beveled edges can be extruded using custom molds. Chalco can assist with rapid mold development and provide technical confirmation and prototyping services.

Selection suggestion: If your structural design is special and needs to match specific equipment or installation interfaces, it is recommended to provide drawings. We will develop a customized mold plan for you to ensure that the molded structure is highly compatible with the installation environment.

FAQ

What is the minimum bending radius of titanium angle steel?

It is generally recommended that the minimum bending radius be 3 times or more of the material thickness to avoid cracking or deformation. For thick-walled titanium angle steel or high-stress applications, hot bending or preheating is recommended to ensure structural integrity.

Can titanium angle steel be welded to stainless steel?

Yes, but you need to use titanium-compatible welding wire (such as the ERTi series) and use an inert gas (such as argon) to prevent oxidation during welding. After welding, the dissimilar metals should be electrochemically isolated to avoid galvanic corrosion.

What are the advantages of titanium angle steel over fiberglass reinforced plastic (FRP) or aluminum profiles?

Titanium has a higher strength-to-weight ratio, natural corrosion resistance, and excellent high-temperature resistance. Its lifespan under long-term loads, marine, or highly corrosive environments far exceeds that of FRP or aluminum, making it more suitable for use in critical structures.

Can titanium angle steel be used for outdoor long-term structures?

Absolutely. The self-passivating oxide film on the surface of titanium can resist erosion from rain, salt spray, acidic gases, etc., and requires no spraying or maintenance. It is often used in structural support components in coastal buildings, offshore platforms and chemical plants.

Can titanium angle steel be subjected to secondary processing, such as welding or drilling?

Supports conventional cutting, drilling, tapping, welding and other processes. It is recommended to use special tools and lubrication and cooling systems for machining, while controlling the heat-affected zone to ensure stable performance after welding.

Do you support small batch orders or sample trials?

Chalco Titanium offers a small order quantity service. Free samples of regular sizes in stock can be provided for size verification, process testing or trial installation, reducing the customer's early development risks.

What certifications can the titanium angle steels provided by Chalco pass?

We can provide EN 10204 3.1 / 3.2 material reports on demand, support RoHS, REACH, AS9100, ISO 9001, CE and other certifications, and assist customers with project reviews and international customs clearance.
