Nuclear Industry:
In the construction of nuclear reactors, the manufacturing of numerous components, pipes, and related parts relies heavily on the support of titanium metal and its alloys. Titanium alloy screws are an important application of these metallic materials.
Electronic Equipment:
In the past, electronic devices such as mobile phones and computers were often fastened with steel screws. However, steel is magnetic, and without proper demagnetization, steel screws can become magnetized under electromagnetic fields, interfering with network signals. In contrast, titanium alloy screws are non-magnetic, lightweight, and high-strength, making them ideal for use as fasteners in electronic devices.
Medical Industry:
Titanium alloy screws also play an important role in the medical field. Because titanium is a biocompatible metal, titanium alloy screws are widely used in the manufacture of medical devices. Especially in the fixation treatment of clinical fractures and dislocations, titanium alloy screws, with their strength and resistance to deformation, have become indispensable fasteners.
Aerospace:
The demand for titanium alloy screws in the aerospace industry remains strong. Their strength advantage makes titanium alloy screws a key fastener in aircraft manufacturing. Compared to steel screws of similar strength, titanium alloy screws offer significant weight reduction, helping to reduce the overall weight of aircraft. In addition, the excellent elasticity and non-magnetic properties of titanium alloys play a crucial role in preventing screws from loosening and resisting magnetic field interference.
Choosing titanium alloy screws is like choosing athletic shoes; you need to consider your "track" environment.
I. First, consider the material, then the operating conditions:
Pure titanium (ASTM Grade 1/ASTM Grade 2): Highly corrosion-resistant, but not suitable for high-temperature environments (≤300℃), ideal for normal-temperature environments like chemical pipelines.
ASTM Grade 7 (α type): With added palladium, it has even stronger corrosion resistance, able to withstand 300-400℃, the first choice for medium-to-high-temperature corrosive environments.
GR5 (α+β type): High strength and heat resistance (400-500℃), used in aircraft engines and new energy battery packs.
II. Don't forget the processing and protection:
Surface treatment: Polishing is suitable for chemical applications, while machining is more versatile.
Heat insulation coating: Ceramic coating for ≤400℃, organic coating for less corrosive environments.
Lubrication: Aluminum alloy structures are coated with 16-alcohol, titanium structures must use dry film lubrication (e.g., MoS₂). Countersunk Phillips head titanium screws, titanium 2 bolts, 6AL4V titanium alloy screws, complete specifications, Ruida brand
III. Price and Customization
Price: 1 RMB/piece is the common price, but customization may be more expensive.
Customization: Supports length, surface treatment, etc., select according to needs.
Summary in one sentence: Choose GR5 for high temperature, choose ASTM Grade 7 for strong corrosion, and use pure titanium for room temperature. Remember to use coating and lubrication!
