Titanium Fasteners

Titanium Fasteners M2–M25: Gr1, Gr2 and Gr5 Bolts, Screws, Nuts and Washers

Some joints have to stay light and hold up against chloride. Marine work is one case. Aerospace and racing are others. That is why engineers there often pick Titanium Fasteners in Gr1, Gr2 or Gr5. Shaanxi Chuanghui Daye Metal Material Co., Ltd. supplies titanium bolts and screws. Nuts and washers come from the same source. Sizes run from M2 to M25. Lengths get cut to your request. Baoji High-tech Development Zone is where the company sits, a place many people call China's "Titanium Capital." Its founder brings more than 30 years of rare metal industry experience. Goods follow GB, DIN and ISO standards. Cartons are one shipping option. Any packing method you specify also works.

What Are fasteners?

Titanium bolts, screws, nuts and washers are joining parts. Commercially pure Gr1 and Gr2 cover most of them. Gr5 (Ti-6Al-4V) alloy covers the rest. A high strength-to-weight ratio is what some designs need, and these parts suit them. Harsh environments are another fit.

Put titanium beside steel or stainless steel standard parts and two practical gains show up. Chloride pitting in marine and offshore service does not trouble it. Pair it with carbon fiber reinforced polymers (CFRP) and galvanic corrosion stays away. Ti-6Al-4V also has a typical density of about 4.43 g/cm³. Parts can therefore come out roughly 45% lighter than steel parts of the same size. These figures are typical alloy values. They are not guaranteed product specifications.

Frames, suspension parts, and rotating assemblies are the places where this product earn their keep. In those spots, both mass and corrosion matter.

Material Grades: Gr1, Gr2 and Gr5

Gr1 and Gr2 are commercially pure titanium. Loads are moderate in the uses they fit, and corrosion is what drives the choice. Chemical handling is a common example.

Need more strength in a structural joint? Gr5 (Ti-6Al-4V) is a good fit. Annealed, the alloy usually holds minimums of 895 MPa tensile strength and 828 MPa yield strength. Whether that beats a given steel property class comes down to the design. Run the numbers first. Steel bolts, Grade 12.9 in particular, should not be swapped out on a guess.

Galling is a common headache. Ask for a surface treatment, anodizing or DLC (Diamond-Like Carbon) coating, for example. When you send the request, put the base grade and the finish on the same line.

Key Properties of Titanium

Magnets have no pull on titanium, and a TiO2 oxide film forms on its surface and repairs itself. That film is this product hold up well in seawater, and in many chloride and oxidizing environments too. Temperature, concentration, and crevice conditions still decide whether a grade fits. Describe your service environment when you ask for a quotation.

Applications

Titanium Fasteners get picked when weight and corrosion resistance matter. Every sector has its own reason for that.

• Aerospace and defense: Airframe parts and engine structures, the places where low weight matters. Heat makes titanium grow less than steel does. Galvanic trouble with CFRP gets avoided as well.
• Marine and chemical processing: Gear that has to handle seawater or process fluids carrying chlorides. There, corrosion decides how often maintenance comes around.
• Automotive and racing: Suspension parts, plus rotating or reciprocating parts. Less mass there can sharpen handling and speed up acceleration.
• Medical and electronics: Parts placed close to powerful magnets or delicate circuits. In such places, non-magnetic parts do a better job.

Quality Checks to Specify

The data you sent has no inspection methods or certificates in it. So tell us in your inquiry which checks your project needs:

• Chemical composition: Gr5 balances aluminium and vanadium. Oxygen, nitrogen, and hydrogen show up too. Too much oxygen makes titanium brittle.
• Mechanical testing: Tensile and proof load tests are part of this step. They check strength against your design requirement.
• Microstructure: Metallographic checks look for alpha case. This is a brittle surface layer with extra oxygen. It can form during heat treatment. Later, it can lead to fatigue cracking.
• Thread inspection: We gauge the threads to check geometry. That cuts the chance of galling when the part goes in.

Please confirm with us which checks and documents can be supplied for your order.

Be used in a wide range of industries.

Purchasing Considerations for Titanium Fasteners

Match the grade to the load before you order this product. Gr1 and Gr2 suit corrosion-driven jobs with moderate loads. Gr5 is the one for structural joints.

Think about the mating material as well. Aluminum is less noble than titanium. Aluminum threads in saltwater therefore need insulating washers or isolating compounds.

Marine work calls for a look at what the part costs over its whole life. Longer gaps between servicing in seawater duty can cut downtime.

Put the quantity in your inquiry. Add the size range too, plus the length and the grade. Sizes made to your drawing are available on request.

FAQ

Q: Why do titanium bolts gall, and how do you stop it?

A: Titanium cold-welds easily when it slides against another surface under load. Make sure the setup fits your application first. Then put on a decent anti-seize compound. Molybdenum disulfide paste is one option. Anodizing and DLC coating are worth asking about too.

Q: Should I choose Gr2 or Gr5?

A: Gr2 fits corrosion-driven work at moderate loads. For structural joints that need more strength, go with Gr5.

Q: Can titanium bolts take the place of Grade 12.9 steel bolts?

A: Not automatically. Grade 12.9 has a higher ultimate tensile strength than Gr5. Steel also has a higher shear modulus than titanium. Someone has to check the engineering first.

Q: Are these bolts and screws magnetic?

A: No. Titanium is non-magnetic.

Q: What goes on when titanium and aluminum threads come together?

A: On the galvanic scale aluminum is the lower metal. Titanium sits above it. This makes titanium cathodic to aluminum. Drop the pair into saltwater and the aluminum threads can corrode galvanically. Insulating washers help. Isolating compounds do as well. Both are strongly recommended.

Q: What sizes, grades, and standards can I get?

A: Gr1, Gr2 and Gr5 in M2~M25 × L, or as your request, to GB, DIN and ISO standards.
