Titanium Stamping: The Ultimate Guide for Engineers & Buyers

What is Titanium Stamping?

Titanium stamping refers to the simultaneous use of a pressure machine and die to apply pressure to a titanium sheet, at which point the titanium sheet will deform or separate, and finally acquire a specific shape, size and performance of the part.

The Process Flow of Titanium Stamping

Step 1: Blanking and Pretreatment:

The edges of the titanium material are polished by laser cutting or waterjet cutting. Cut the titanium sheet into the desired shape.

Step 2: Coating:

Apply lubricating materials or antioxidant coatings to the surface of the titanium material to be stamped.

Step 3: Stamping:

Utilize the die and stamping machine to quickly punch into the shape you want on the press.

Step 4: Follow-up:

The molded titanium surface is pickled or sandblasted. In addition, heat treatment is sometimes required to ensure precision; Finally, vacuum annealing is required to eliminate residual stresses inside the titanium material.

What Makes Titanium Metal Stamping Different From Steel/Aluminum?

Titanium’s unique physical and chemical properties make the stamping process more complex than that of traditional metals.

• High Rebound

Titanium has a low modulus of elasticity, so even after the part is stamped, once the pressure is canceled, the titanium material will tend to return to its original state, which will lead to low accuracy of the final machined part.

• Stick the Mold

Titanium is extremely chemically active, and during high-pressure stamping, titanium atoms and iron, chromium, nickel and other atoms in the mold are easily attracted to each other, resulting in adhesion between the material and the mold. In this case, a special coating can be used to lubricate it.

• It is Easy to Crack When Processed at Room Temperature

Industrial pure titanium (CP Titanium) is stamped at room temperature and plasticity is okay, usually using the cold stamping process; However, titanium alloys, especially TC4 (Ti-6AL-4V) titanium alloys, are very prone to cracking at room temperature, so they usually need to heat the material before processing. The hot stamping process is usually used.

• High Hardness

During the processing of titanium, the hardness will increase rapidly, so the difficulty of subsequent processing will also increase.

Titanium Grade Selection for Stamping

• Industrial Pure Titanium – Titanium Grade 1 Grade 2（CP Titanium）

Industrial-grade pure titanium offers excellent ductility and formability. Whether it involves deep drawing, bending, or machining complex shapes, it is relatively easy to work with.

• Titanium Alloy – Titanium Grade 5 (Ti-6Al-4V)

Gr5 titanium alloy has very high strength, usually using the titanium hot stamping process, which is carried out at high temperatures, and the titanium plate must be heated to about 500-700°C.

• Titanium Alloy – Titanium Grade 9 (Ti-3Al-2.5V)

Gr9 titanium alloy has very good plasticity and medium strength, making it suitable for deep drawing, bending and forming operations without any problems, and does not require heating, usually cold stamping.
