Tungsten alloy rods can be divided into the following types according to the surface treatment process:
1. Light rod: the original tungsten alloy rod without any surface treatment, the surface is rough, usually used for general machining.
2. Grinding rod: The surface of the tungsten alloy rod has been ground or ground, the surface quality and smoothness have been improved, and it is mainly used for precision parts processing.
3. Galvanized rod: Tungsten alloy rod with electro-galvanized surface, used in occasions that require anti-corrosion requirements, the zinc layer can play a certain role in anti-corrosion protection.
4. Anodized rod: The surface of the tungsten alloy rod after anodic oxidation treatment forms a dense oxide film on the surface, which not only improves the surface quality, but also has certain anti-corrosion properties. Commonly used in precision mechanical parts.
5. Black tempered rod: The surface of the tungsten alloy rod after black tempering dipping treatment forms a black dense quenching layer on the surface, which has high hardness and wear resistance, and is often used in parts such as molds.
6. Silver tempered rod: The surface of the tungsten alloy rod after silver tempering and dipping treatment forms a silver dense quenching layer on the surface, which is both pre-hardened and non-magnetic, and is used for precision parts processing with special requirements.
7. Spinning rod: the surface of the tungsten alloy rod has been treated by high-pressure spinning, the surface quality and smoothness are greatly improved, and it has hydrophobic and anti-corrosion effects, which is used for high-end equipment manufacturing.
8. Electrophoretic rods: Tungsten alloy rods coated with electrophoretic paint on the surface, which are beautiful and anti-corrosion, and are usually used in non-mechanical structures such as architectural decorations.
Therefore, tungsten alloy rods can be divided into smooth rods, ground rods, various tempered rods, galvanized rods, anodized rods, spinner rods and electrophoresis rods according to different surface treatment processes. This provides a reference for the selection of tungsten alloy rods that meet different usage environments and requirements.
