Titanium alloy screws are high-strength, lightweight screws that are widely used in aviation, aerospace, automobiles, ships, and other fields. It has high corrosion resistance, high-temperature stability, and excellent mechanical properties. It is a high-performance material. Let's follow our titanium aviation screw manufacturer today to learn about the knowledge of titanium alloy bolts and nuts.
1. Material selection standards for titanium screws:
In the customization of titanium screws, the selection of materials is the primary priority. Users need to choose titanium aviation screw manufacturers according to the extreme use environment (high temperature, high pressure, strong corrosion, strong force, etc.) that the screws will encounter. For example, TC4 (Ti-6Al-4V, widely used in the aerospace field) and TA2 (pure titanium, with excellent corrosion resistance and good formability) are the keys to ensuring the stability of screw performance and long life.
2. The production process of titanium screws The basic manufacturing methods of titanium alloy screws are cold heading and machining (turning, milling, etc.).
The definition of cold heading is to use the plasticity of metal and use cold mechanics to press or cold draw to achieve the purpose of solid metal forming. A forging method that thickens the top of a bar or wire at room temperature.
3. Classification of titanium screws
Titanium screws: round head screws, self-tapping screws, hexagonal screws, countersunk screws, slotted screws, square head screws, stud screws, non-standard screws, fastening screws, standard screws, flat head screws.
Titanium bolts: hexagonal bolts, square neck bolts, half-round head bolts, countersunk bolts, carriage bolts, sleeve combination bolts, various instrument lathe bolts, and special-shaped non-standard bolts. Applications: electroplating, aluminum oxidation (anodic decomposition), chemical industry, watch industry, medicine, breeding, electronic hardware, plastics and other industries.
Titanium nuts: hexagonal nuts, self-locking nuts, ring nuts, knurled nuts, slotted nuts, hexagonal nuts for precision machinery, special-shaped non-standard nuts.
4. Surface treatment of titanium screws
The surface treatment methods in the implementation standards of titanium bolts and nuts include natural surface, chemically matte (black) surface, electroplated surface, and anodized surface.
Among them, the natural surface is mainly used in occasions with good corrosion resistance, the chemically matte surface is used to prevent reflection and beautify the surface, the electroplated surface is used to improve the surface hardness and wear resistance, and the anodized surface is used to improve the corrosion resistance and fatigue resistance of the material.
In short, when purchasing titanium bolts and nuts, you need to choose according to the specific usage scenarios and needs. At the same time, you need to choose a titanium aviation screw manufacturer with quality assurance to ensure the quality and use effect of the product.
