Titanium Alloys Products: Engineered for Extreme Conditions
As a Titanium alloys products manufacturer, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.
Zhejiang Donghe Machinery Technology Co., Ltd. is a high-tech enterprise and a leading Titanium alloys products manufacturer in China, specializing in the development and production of titanium fasteners for industries that demand exceptional strength-to-weight ratio, corrosion resistance, and biocompatibility. Our range includes titanium self-tapping screws, hex bolts, nuts, washers, and custom-machined components, all manufactured to international standards including GB, DIN, ANSI, and BS.
With over 100 sets of machines, a dedicated R&D team, and an annual production capacity of 8,000 tons, we supply titanium fasteners to aerospace, marine, chemical processing, medical, and high-performance automotive sectors across Europe, Australia, Africa, and the Americas. Our factory is ISO9001:2000 certified, and we operate our own testing laboratory to ensure every batch meets stringent quality requirements.

Material Grades and Specifications
Titanium alloys offer a unique combination of properties: density about 4.5 g/cm³ (roughly 60% of steel), tensile strength up to 1000 MPa in alloyed forms, and excellent resistance to seawater, chlorides, and many acids. We commonly work with commercially pure titanium (Grade 2) for general corrosion resistance and Ti-6Al-4V (Grade 5) for higher strength applications. For specialized needs, we can source other grades such as Ti-6Al-4V ELI for medical implants or Ti-3Al-2.5V for aerospace tubing.
Our manufacturing processes include cold heading, CNC machining, and heat treatment, allowing us to produce fasteners with precise tolerances and consistent mechanical properties. We also offer surface treatments like anodizing or passivation to enhance wear resistance and appearance.
Application Fit and Engineering Support
Selecting the right titanium fastener involves considering the operating environment, load requirements, and mating materials. Our engineering team assists in material grade selection, thread design, and coating choices to ensure optimal performance. For example, in marine applications, we recommend Grade 2 or Grade 5 with a smooth surface finish to minimize biofouling. In chemical processing, we evaluate resistance to specific media and temperature ranges.
We also provide guidance on installation torque values, preload specifications, and galvanic corrosion prevention when titanium is used with dissimilar metals. Our goal is to deliver fasteners that not only meet but exceed your performance expectations.
Quality Assurance and Testing
Quality is embedded in every step of our production. We operate an in-house laboratory equipped with advanced inspection tools, including optical sorting machines and hardness testers. Each batch undergoes dimensional verification, thread gauging, and mechanical testing (tensile, yield, hardness) to ensure compliance with ISO and customer specifications. Our quality management system is ISO9001:2000 certified, and we continuously invest in new testing equipment to maintain high standards.
For critical applications, we can provide material certificates, test reports, and traceability documentation. We also conduct salt spray testing for corrosion resistance and can perform ultrasonic or X-ray inspection upon request.
Customization and OEM/ODM Services
We understand that off-the-shelf fasteners may not always fit your design. As a flexible Titanium alloys products supplier, we offer full customization services: you can send us a drawing, a sample, or just a specification, and our R&D team will develop a solution. We can adjust dimensions, thread pitch, head style, and material grade to meet your exact requirements. We also support private labeling and packaging customization for distributors.
Our non-standard fastener capabilities are particularly strong, as we have experience with complex geometries and tight tolerances. Whether you need a small batch for prototyping or large-scale production, we can scale our processes accordingly.
Information We Use to Configure Your Solution
To prepare an accurate quotation and engineering proposal, we typically need the following information from you:
- Detailed drawings or samples with dimensions and tolerances
- Material grade preference (e.g., Grade 2, Grade 5) or performance requirements
- Quantity and packaging requirements
- Application environment (temperature, corrosive media, load conditions)
- Standards to be met (GB, DIN, ANSI, BS, or internal specs)
- Any surface treatment or coating needs
- Delivery timeline and destination
With this information, we can provide a tailored solution that balances performance and cost-effectiveness.
Maintenance, Service, and Global Delivery
Titanium fasteners require minimal maintenance due to their inherent corrosion resistance, but proper installation and periodic inspection are recommended for critical joints. We provide technical documentation, including installation guides and torque charts, with every shipment. Our after-sales team is available for troubleshooting and replacement support.
We export worldwide with reliable logistics partners, ensuring safe packaging and on-time delivery. For large orders, we can arrange sea freight or air freight based on your urgency. We also offer warehousing solutions for regular buyers.
Frequently Asked Questions
What titanium grades do you stock?
We primarily work with Grade 2 (commercially pure) and Grade 5 (Ti-6Al-4V), but we can source other grades like Grade 1, Grade 3, or Ti-6Al-4V ELI on request. Tell us your application, and we'll recommend the best grade.
Can you produce titanium fasteners to non-standard dimensions?
Yes, we specialize in custom fasteners. Send us your drawing or sample, and we'll manufacture to your exact specifications, including thread forms, head styles, and lengths.
What is the minimum order quantity for titanium fasteners?
MOQ varies by product type and size. For standard items, it can be as low as 500 pieces; for custom parts, we evaluate based on complexity and material availability. Contact us for a specific quote.
Do you provide material certificates and test reports?
Yes, we can supply mill certificates, mechanical test reports, and dimensional inspection reports with each batch. This documentation is available for both standard and custom products.
How do you ensure corrosion resistance in marine environments?
We recommend Grade 2 or Grade 5 titanium with a smooth surface finish. We can also perform anodizing to enhance oxide layer thickness. Our fasteners are tested in salt spray chambers to verify performance.
