HTL Titanium

Titanium plate is a metal plate manufactured using titanium as the raw material. Titanium is a very special metal, known for its lightweight yet strong and corrosion-resistant properties. Unlike silver, it does not tarnish and maintains its original color at room temperature throughout its lifetime. Titanium has a melting point similar to that of platinum and is widely used in industries such as metallurgy, electronics, medical, chemical, petroleum, pharmaceuticals, and aerospace.

Standards:

Standards include but are not limited to: AMS4900, AMS4901, AMS4902, AMS4904, AMS4907, AMS4911, AMS4914, AMS4916, AMS4919, ISO5832-2/3, ASTM F136, ASTM F67, GJB2505, GB/T3621, ASTM B265.

Grades:

GR1、GR2、GR3、GR5、GR7、GR12,etc.

The allowed deviation of thickness for titanium plate is as follows:

For American standards, the deviation is 0.05% for GR1-GR7 and 0.1% for GR8-GR12.

Manufacturing Processes of Titanium Plate:

1. Hot Forging: A forging process carried out above the recrystallization temperature of the metal.
2. Hot Rolling: A rolling process conducted at a temperature higher than the recrystallization temperature.
3. Cold Rolling: A rolling process performed at a temperature lower than the recovery temperature, where plastic deformation occurs.
4. Annealing: A metal heat treatment process that involves slowly heating the metal to a specific temperature, holding it for a sufficient time, and then cooling it at an appropriate rate (usually slow cooling, sometimes controlled cooling).
5. Acid Pickling: Immersing the workpiece in a water solution containing sulfuric acid to remove oxide films and other contaminants from the metal surface. It is a pre-treatment or intermediate treatment for processes such as electroplating, enamel coating, and rolling.

Characteristics of Titanium Plate:

1. The oxide film on the surface of the titanium plate acts as a durable and effective anti-adhesive agent. The use of titanium plate eliminates the need for a separating agent, making it easy to peel off the electrodes and eliminating the need for pre-treatment. Titanium plates are also half the weight of copper plates.
2. The lifespan of titanium plate is more than three times that of copper plates and can reach 10 to 20 years depending on operating conditions.
3. Electrolytic copper produced using titanium plates has a dense and smooth crystal structure, resulting in superior quality.
4. Titanium plates do not require the application of separating agents, thus avoiding contamination of the copper electrolyte.
5. Improved productivity and reduced production costs of electrolytic copper, resulting in better economic benefits.

Surface Quality of Titanium Plate:

1. The surface of the plate should be smooth and exhibit the natural color of the metal. Supplying the plate with a sandblasted surface is acceptable.
2. Slight dullness, localized watermarks, and minor scratches, indentations, or pits that do not exceed half the thickness tolerance are allowed but should ensure the minimum thickness is maintained.
3. Macroscopic defects such as cracks, peeling, oxidation, folding, and metal/non-metal inclusions, as well as traces of excessive alkaline cleaning, are not permitted on the surface of the plate.
4. Localized defects along the rolling direction are allowed, but the thickness of the plate after removal of these defects should not be less than the minimum allowed thickness.
5. When there are special surface quality requirements for the plate, supply can be negotiated between the supplier and the buyer.
