Ti sheet. Whats it worth | MIG Welding Forum

That’s grade 1 Ad.
The most workable grade and probably the most expensive in that thickness.
Most common grade is likely to be 2 but as they come out of BAE they could be anything.
@Brad93 knows his Ti really well.
He might be able to tell you the grade based on the number etched on the sheet because @Shox Dr you cannot get a value on Ti without knowing the grade. The difference in price is pretty huge between them.
A mate has 5 sheets of .9mm titanium. Unsure of the grade, has ‘ZSLH H’ ecthed on one side.
Came from BAE at Brough. x680 in size. There are some 6mm holes in the shhets, approx 25mm from the edge, here and there.

Any ideas as to its value?

0.9mm is a useful thickness. 6mm holes in it, i would say its been used as shielding or cowling.

The numbers provided don't jog anything I've ever seen. "H" i would say is a heat number (batch number) from the melt. ZSLH is probably an internal reference.

Easy way to tell is, can you bend it? If you can put a small offcut and bend it and produce a nice tight bend in a vice, its most likely Grade 1 or Grade 2.
If you get a radius'd bend and it has tonnes and tonnes of spring back its likely one of the alloyed grades.

Grade 1 and Grade 2 are useful because they can be formed using conventional methods - to a degree. The other grades are so bloody strong and some brittle they are useless except for making flat parts.


Expensive then

The prices from online suppliers are ridiculous. I can buy a 2m x 1m sheet of Grade 1 CP for about £450 in 0.9mm. Delivered.

Titanium Plates and Sheets in the Aerospace Industry

Titanium is a unique metal noted for its strength, lightweight, and corrosion resistance. It has become a go-to material in various industries, including aerospace, medical, and construction. The aerospace industry relies on this material as it offers an impressive strength-to-weight ratio, thermal stability, and chemical inertness. To understand the importance of titanium in this industry, the following key areas are discussed in this guide including properties, applications, and benefits of titanium plates and sheets.

History of Titanium

Titanium has a fascinating history that dates back to the 18th century when it was first discovered by William Gregor, a British mineralogist. It was not until that Matthew A. Hunter, an American metallurgist, produced pure titanium by reducing titanium tetrachloride with sodium. However, the high cost and difficulty in extracting and refining the metal limited its use until World War II when its unique properties were recognized by the military.

Its application expanded significantly over this period. The United States, in particular, employed this metal to build military aircraft. After the war, the use of titanium broadened as new production processes surfaced, which reduced costs. In the s, commercial production of titanium began, and by the s, it was widely used in aerospace and defence applications.

Over the years, titanium’s utility has extended beyond its original application and is seen in diverse fields such as medical implants, sports equipment, and high-performance automobiles. Today, titanium stands as a vital component of modern engineering, with its properties being constantly researched and fine-tuned for novel applications.

Properties of Titanium

Today, titanium is widely used in various industries due to its unique combination of properties. It has a low density of 4.5 g/cm3, which is about 60% of steel, and a high strength-to-weight ratio, making it strong enough to withstand high stresses and loads while remaining lightweight. Additionally, it is highly resistant to corrosion in most environments, including seawater, acids, and alkalis.

Titanium Production Process

Titanium is transformed from ore to a finished product by a series of operations, the number of which varies according to the intended purpose.

Extraction

Titanium is typically found in mineral sands which are mined and processed to extract the metal. This involves crushing and grinding the mineral sands, followed by a chemical process that separates the titanium from other minerals. The resulting titanium dioxide is then purified.

Purification

After the extraction of titanium from mineral sands, the next step in the production process is purification. During purification, the extracted titanium dioxide is further processed to produce a highly pure form of titanium. The purification process is critical because even small impurities can significantly affect the properties of the final product.

One common method of purification is the Chloride Process. In this process, the titanium dioxide is reacted with chlorine gas to produce titanium tetrachloride (TiCl4), a highly reactive compound. This compound is then purified through fractional distillation, which separates it from other impurities.

Once the purified TiCl4 has been obtained, it is reacted with magnesium or sodium in a high-temperature reaction to produce metallic titanium. The result of this reaction is a highly porous, sponge-like material that can be further processed to produce titanium alloys.

Sponge Production

This involves reducing the titanium dioxide using a high-temperature reduction process, typically in the presence of a reducing agent such as carbon. The result is a porous, metallic material known as a titanium sponge.

Alloy Production

The titanium sponge is then further processed to produce titanium alloys. It involves melting the sponge in a vacuum or inert gas atmosphere and then adding other metals to produce the desired alloy. The resulting alloy is then cast into ingots, which can be further processed into various forms, including sheets and plates.

Application of Titanium Plates and Sheets

The aerospace industry heavily relies on titanium plates and sheets, as their exceptional properties make them ideal for use in aircraft structures, engines, and other components. Most importantly, the metal’s high strength-to-weight ratio is useful in this industry, where weight reduction is a critical factor in improving fuel efficiency and performance. The applications include:

Aircraft Structural Components

Titanium is an excellent material for aircraft structural components such as wing spars, landing gear, and engine mounts. Its high strength-to-weight ratio makes it ideal for these applications, as it allows for the manufacture of lightweight yet strong components that can withstand the stresses and loads experienced during flight.

Engine Components

The engine is one of the most important parts of an aircraft, and it needs to be made from materials that can withstand high temperatures and pressures. Titanium is perfect for this job, thanks to its high melting point and thermal stability. It’s used to make components like blades, disks, and casings, which are essential for keeping the engine running smoothly while maintaining its shape and integrity.

Fasteners

In the aerospace industry, even the tiniest components need to be incredibly strong and reliable. That’s why titanium fasteners are so popular – they’re lightweight, corrosion-resistant, and tough. They’re used to secure everything from the wings to the fuselage, ensuring that every part of the aircraft stays in place during flight.

Heat Exchangers

Finally, titanium is used to manufacture heat exchangers that are used in aviation cooling systems. Its high thermal conductivity means that it can efficiently transfer heat away from critical parts, keeping the aircraft cool.

Benefits of Titanium Plates and Sheets

There are numerous benefits to using titanium plates and sheets in aerospace applications. These include:

  • Increased formability
  • Increased strength
  • Less material required unlike steel or aluminum
  • Lower density than other alloys
  • Higher temperature resistance
  • Corrosion resistance

Pricing Information for Titanium Plate and Sheets in the USA

The price of titanium plates and sheets in the United States varies, depending on the grade, thickness, and size of the material. Recent findings show that the price of titanium plates and sheets in the USA ranges from $15 to $85per kilogram, depending on the grade and thickness of the material. Higher-grade titanium alloys such as Ti-6Al-4V and Ti-6Al-4V ELI are more expensive than lower-grade alloys.
